SHA512 was adapted from a few public domain sources and pseudocode from
wikipedia. The entropy collector gathers entropy from keyboard events and
mouse movement - and, just for fun, from screenshots.
The entropy pool is saved at program exit and reloaded at program start.
Entropy is used to re-seed the pseudorandom generator (not that it would
make a difference).
* do not use std::abs() because math.h includes one, that converts ints
to double. Use own iabs(), which directly uses labs() instead.

According to SDL documentation, the SDL implementation of timedwait may
suck on some platforms, so it should only be used, where high CPU usage
during the wait is no issue.
getpckserver() will now only wait for one second for access to the
package server list and return an error instead of waiting indefinitely.
getmod modname
Try to download mods/modname.zip from all configured package servers.
Does not automatically activate the mod. The zip files are limited to
one megabyte total.
DOCREF getmod
* own source file for autodownload
* use cleaned up zip functions
* use new http get function (no more curl)
* enforce strict file naming rules and file size limits
* ping all package servers on every game start to determine ping times
* support media file update lists (also kept on package servers)
* allow users to manually prioritise package servers
* automatically select server with newest media file revision
new or changed commands:
addpckserver hostname [priority]
Adds a host name to the list of package servers. If a priority is given,
it influences the sorting of servers. Servers with higher priority are
queried first. If servers have the same priority, they are sorted by
ping. Default priority is zero.
getpackageserver
Returns a table with four columns of all configured package servers. The
columns are: host name, priority, ping and resolved.
"resolved" is a flag, indicating, if the server answered the ping during
game start.

Check printf-like functions like conoutf, if format strings and argument
lists match.
This commit also fixes a lot of code parts that actually had mismatching
argument lists - or did things, that this check does not like.
numtime() was rewritten in an ugly but very portable fashion (it's
recommended to stay away from "long long" format entries, because errors
usually only come up at runtime).

"findfilelocation" contains the location, where the file was found.
Not a nice solution, but nice enough :)
Note: if the location is FFL_WORKDIR, the existence of the file has not
actually been checked yet.
This adds a means to store additional attributes for mapmodels, including
a caching mechanism, so the mapmodels don't have to be loaded to access
the information. The goal is, to provide fully automatic mapmodel menus
for map editing who also add information about downloaded mapmodels.
Model attributes are extracted everytime, when a model is loaded. At game
end, all available data is written to config/mapmodelattributes.cfg and
restored at next startup. On release, a file with all (but only) official
models should be included. Since autodownloaded models are usually "loaded"
after download, those are automatically added to the database. If someone
adds models manually to the directories (media pack, w/e), the command
"loadallmapmodels" can be used to try to find all available models. The
only way to delete something from the database, is to delete the file
config/mapmodelattributes.cfg when the game is closed.
The current list of attributes is:
keywords
List of one or more menu topics to list the model under. Check
config/menus_edit.cfg for available keywords. Unknown keywords will
be listed separately.
desc
Short name or description of the model. Will be used as menu entry.
usage
Important information for how to use that specific model.
author
Who created the mapmodel. If it's a derivative of another model, state
the author of the mod (refer to the original author under "license", if
you like). Always use the exact same spelling for the same author, to
allow menus to automatically group models by author.
license
Free-text attribute for license info or info about additional
contributors (or original authors for derivated works).
distribution
One of "official", "autodownload" or "manual". Other values default to
"manual". This is used to determine, if a map contains only original
media or media that can be download automatically.
version
Single numerical value to separate older from newer versions. Defaults
to zero. Higher numbers mean "newer". Maybe someone manages to implement
a versioning system for custom media in the future...
New commands:
mdlattribute <attr> <value>
To be used in model config files. Adds a value for a specified
attribute to the model.
mapmodelregister <modelpath> <attr1> <attr2> ...
Adds values for all attributes to a specific mapmodel. This is used to
restore the cached values from config/mapmodelattributes.cfg during
game start. Does not actually verify of load the model.
mapmodelattributes <modelpath> <attr>
Returns the value of a specific attribute of a mapmodel. If modelpath
is a number, it is interpreted as index for the list of models in the
current map config. If no attribute name is specified, all attributes
are printed to the console instead.
getmapmodelattributes <list of attribute names>
Returns a table of all known mapmodels. Each model is listed with the
modelpath and the values for the requested attributes. To be used
instead of a fixed table in menu_edit.cfg. In addition to attribute
names, the function also allows the keywords "explodekeywords" and
"sortby:" as arguments. If "explodekeywords" is given, all mapmodels
with more than one keyword are listed multiple times, once for each
keyword. If an attribute name is preceeded by "sortby:" the list will
be sorted by this table column. If "sortby:" is used several times,
this first sort will have highest priority. The list is always sorted
by path by default.
example:
getmapmodelattributes sortby: author sortby: desc explodekeywords
loadallmapmodels
Tries to load mapmodels from /all/ paths below packages/models/mapmodels.
Will throw a lot of error messages, because not all directories contain
models to load. This command can be used to build or rebuild the
complete list of all available mapmodels. It is only necessary, if models
are added manually to the directories, since every mapmodel gets added
to the list when it is loaded - which takes care of all automatically
downloaded models.

The light calculation requires the random generator to be seeded with a
constant - otherwise repeated light recalculations would make the lights
change.
This patch allows the random generator to go back to the state before the
static seed().
Renames the existing saved.cfg to saved-old-1.cfg (and an existing -1 to
-2, and so on) before the new saved.cfg is written.
This should help in cases where players mess up their config, because the
config is deleted with a five-game-starts delay.
The logfile can't be created before the commandline arguments are parsed,
because before that, the home directory is unknown. This patch logs
into a memory buffer which is then copied to the logfile as soon as
the logfile is created after processing the commandline arguments.
The memory buffer is created during the initialisation of global variables,
and destroyed after the logfile is created.
An xmap holds everything related to map editing at a certain moment: it is
a map editing snapshot. It contains the name, the header, the geometry,
the entities, the extra headers, the undo/redo data and the cameraposition
from the moment, the snapshot was taken.
Xmaps are held in memory and, if persistentxmaps is set to "1", are saved
at game end and restored at game start.
xmap_list
lists all xmaps currently in memory
xmap_store <nickname>
create a snapshot and store it under the given nickname
(nicknames have to qualify as valid filenames)
xmap_restore <nickname>
restores the named snapshot. Also creates a backup snapshot of the
current editing data.
xmap_restore
restores the last automatic backup snapshot. Automatic snapshots are
taken, a) before a snapshot is restored, b) before a new map is loaded
(if there were unsaved edits on the map) and c) when the game ends (if
there were unsaved edits).
xmap_delete <nickname>
deletes the named snapshot.
Unsaved edits are flagged in the HUD with an "U" in the lower right
corner of the screen.
The files with the persistent xmaps are stored in mapediting/xmaps. After
they were restored at game start, the files are moved to
mapediting/xmaps/backups. Xmap files are cubescript files.
This commit establishes an extensible way of storing additional data in
map file headers. Those header extras can be permanent, like the embedded
config file or be used only once after map load like the undo/redo data.
Additional extra data can be easily added and will not break backward
compatibility, so this map format should hold up for quite some time.
To make things easier for mappers, maps can now be saved without invoking
the various optimisations. That, in combination with the stored undo data,
means, that editing a map can be picked up at exactly the same state, as
the map was saved in.
Maps will automatically be written in the appropriate fashion, depending
on the situation:
1) for sendmap: no optimisation, no undo data
2) savemap during editing: no optimisation, with undo data
3) savemap when not editing: optimised, no undo data
4) savemapoptimised: optimised, no undo data
(For savemap to save different maps during editing, the variable
preserveundosonsave has to be "1". It is "0" by default.)
All of the above map files can be played without problems - they only
differ in file size. (However, maps with undo data may be too big to send)
The new command "embedconfigfile" will load the config file, include it in
the map header and rename the original text file.
"extractconfigfile" will write an embedded config file to a separate file
and remove it from the map header.
Embedded config files take precedence over regular config files and
therefore make it harder for cheaters to play with modified config files.
further changes: cleaned up some debugging code; more ASSERTs
"mapmrproper" tries to optimize hidden attributes of maps in a way, that
the map can be handled in bigger chunks by the renderer.
The mipmapping routine does not take into account, if certain textures
of a cube are visible at all, when it collects otherwise identical cubes
to be handled en-bloc. "mapmrproper" changes invisible textures in a way,
that the cubes are in fact identical - so, that the mipmapper is satisfied.
This optimization is a bit too huge for now, to be used by savemap by
default (instead of toptimize()) - even though mapmrproper is far superior
to toptimize(). Since mapmrproper potentially changes a lot of textures,
it may be too annoying during the creation of a map anyway. It is a tool
to optimize the map, as soon as the geometry (and texturing) is done.
The optimizer does not change any map properties that are visible in any
way. The optical effect of slightly changing lighting of the map is caused
by the (light-) recalc() function at the end of the optimization run.
Every run of recalc() seems to have that effect (check for yourself, by
typing /recalc several times).
Before any changes are made, mapmrproper creates a backup, which can be
restored by "undo" (press "U"). Enable mipstats (F6), to see, what has
been done.
The command "calcmipstats" just counts all the mips in the current map,
and prints their numbers as 1x1/2x2/4x4/8x8/16x16/32x32/64x64.
Keep in mind, that map geometry /and/ lighting affects the mipmapping.
(To get a better idea of this, try changing the "lighterror" parameter)
Older versions of ac did not obey the map header field "headersize".
When a map was written, only the "version" field was updated, even if
the new written header had a different size. Thanks to bigger headers
in map versions 7 & 8 (and now smaller headers again in 9), the headersize
of basically all official maps is bogus. This fix makes sure, only proper
headersizes are written. It also makes the game tolerate different (bigger)
headers - and keeps their content untouched. Future map format extensions
can use this to add header information without breaking existing map parsers.
This patch establishes a new map format 10, which is identical to format 9,
with the exception that the headersize field is guaranteed to be correct.
Format 10 also allows any amount of additional header data.
This patch also cleans up the transformation routines for old map entities.
