Since we clip the world properly even with skyboxes active, and the
'skybox' serverinfo doesn't do anything in any other engine I know of,
nuke the 'skybox' serverinfo entirely and use a nice short semi-standard
name ("sky") for the serverinfo containing the map's preferred skybox
(as potentially modified by the .ent file on the server).
This ensures that the map's sky is always used unless the client itself has
set its r_skyname cvar. The server's r_skyname cvar is now the default
name for the skybox for when the map does not specify one. The map's sky
worldspawn field overrides this. The r_skyname cvar is no longer a
serverinfo cvar.
add qwe builtin extensions to qw-server. provide sv_progs_ext to control
the builtin mapping. valid values are "id", "qf" (our old static builtins),
"qwe"/"ktpro" (either works. for ktpro mod support) and "none" (no
mapping). any other value is equivalent to "none".
ranges can be used efficiently. move the auto-allocated builtins to
0x10000000-0x7fffffff. should be more than enough :)
use static builtin tables ("nul" terminated) instead of a series of
function calls to add builtins to a vm. should be more memory efficient.
all (or most, there are limits still) of the maps on a server with many
maps.
move the optional progs funcs into sv_funcs_t and add UserInfoChanged,
ChatMessage and LocalinfoChanged callback support.
clean up PF_setinfo (and SV_SetInfo_f and SV_Localinfo_f) using shared code
where possible und to use the UserInfoChanged and LocalinfoChanged
callbacks.
add chat message callback to SV_Say. if it returns zero, normal chat
handling is done, otherwise it's assumed to have been handled by the progs.
provide a hook for unkown user commands. non-zero return means it's been
handled.
All the details of game directories will be fully configurable (search
paths and gamecode file name currently supported). Downloading of skins to
qw/skins only currently broken (will download to $gamedir/skins for now).
the SDL target files for Despair since he's working on the currently). Also
make progs segfault handling much more robust (and general: sigill etc too:)
This required changes to the api (info_t instead of char *) but should be
a net gain in speed (not a lot, admittedly: it was pretty fast to begin
with, but this paves the way for some other changes I have in mind).
