Normally we build a fast, unoptimized bsp tree for the world before
culling outside surfaces. This command line switch forces the use of
the more expensive algorithm for this processing stage. Seems to have
a positive effect on the final BSP in terms of reduced marksurfaces
and smaller file size, at the expense of longer processing time.
Marked experimental for now, as it may be removed later (either by
making this behaviour the default or removing it altogether).
Credit to Rebb from func_msgboard for implementing this tweak first in
his qbsp util.

Explicitly pass the face list around to be added to as needed instead
of implicit reference to the global 'newlist'.

Remove the global static buffer and allocate the superface when
processing tjuncs. Also check that we are not overflowing the buffer
before adding more vertices - probably something went wrong if this
ever overflows, so better to crash with a definite error than scribble
random memory.

The way wedge_t and wvert_t were hashed and compared was resulting in
FixFaceEdges being able to get stuck in a loop adding verticies to a face
if two consecutive verticies were very close to EQUAL_EPSILON apart.
Avoid these problems by tweaking T_EPSILON to be slightly wider than
EQUAL_EPSILON.

Took me some time to work out what this was all representing and that t
was the parameter to the parametric equations of the edge's line in 3-d
space. May as well make it easier for others and my future self.

No functional changes, just making the previous cleanup more consistent.
Pointer is non-const now, but no matter.

Mainly tidy up long lines and rename dir/test variables to edgevec[2]
since these are the edge vectors we are testing the angles between.

Since 'w' is commonly used for a winding variable, this makes the code
harder to read. Use the name 'edge' instead for these tjunc local types.

If brushes in the map are textured with alt-animations, and the second
character (i.e. the 'a' in +abutton) is lower case then we have the
lowercase texture name in the miptex list, but when we add alt textures we
use the uppercase, so it gets duplicated. Duplicated animating textures
cause most engines to exit with an error.
Since the map file could use uppercase texture names as well, really we
should either be normalizing texture names to upper or lower case, or we
need to do case-insensitive matching - so I just changed to
case-insensitive matching.

Also do a quick sweep of the source and consistently use %d instead of
%i (no real difference, but just pick one).

Not too intrusive, since the Message() layer still acts as a shim
here. Most of the changes are for the Makefile. Qbsp now links to
the threading code as a result, but no thread support... yet!

Carry over some correctness fixes from recent changes to vis into the
qbsp versions of ClipWinding and make the implementations more
consistent overall.
Most importantly:
* Ensure we always have allocated one extra dists/sides slot for wrap around
* Check we have space for a new vertex every time we try to add one

Factor out some of the processing involved with parsing a brush. When
checking for duplicate planes, use the same "PlaneEqual" functions as
used in brush.c.
Replace the enum style errors with the new Error_ function for all of
map.c so the error string is at the call site.

Call it Error_() for now while I work on transitioning away from the
arrays of global strings hidden away by error enums.

We don't want to terminate the recursion in ClusterContents when we reach
a non-detail separator because we need to know the contents of the leafs!
This was working okay for simple cases but fails when the detail clusters
become more complex.

Don't count skip surface verticies at all in CountData_r because this
count actually gets used as the surfedge count and we need that to be
precise.
Don't try to save memory be allocating less verticies than edges, even
though many will probably be shared. The saving is not that significant
anyway.
Signed-off-by: Kevin Shanahan <kmshanah@disenchant.net>
We still end up short if we just discard these counts - still don't
need faces for them, but every edge could be real unless it's shared
with another skip face.

The old assumption about unique verticies is sometimes untrue when
skip faces are included in the map. Be more generous with the vertex
memory allocation. This is not an area of peak memory usage anyway, so
shouldn't be a big deal.

Extend skip support to recognise the liquid skip texturenames the same as
metlslime's "newskip" utility. Add documentation and describe hint
surfaces (briefly) as well.

The old logic did not deal properly with the case where the source entity
did not add any brushes.
