Here's another little tyrutils patch: in qbsp, I believe the
calculation of the "disksize" field of the miptex lumps when using
WAD3 textures is missing the size of the dmiptex_t struct (40 bytes),
causing the resulting bsp file to be slightly truncated.
I noticed this because one of Tronyn's levels (jam2_tronyn.bsp) was
crashing Quakespasm for me; it turned out the engine was trying to
read 40 bytes past the end of the file when loading the last texture
in the bsp. I got him to send over his map source, wads, and compiler;
he was using tyrutils 0.15 and wad3 format textures, and I confirmed
that this patch fixes the engine crash.

This bug is a counterpart to this bug in quakespasm:
https://sourceforge.net/p/quakespasm/patches/15/
If the precision of the calculation in WorldToTexCoord done by ‘light’
is significantly different than the precision of the same calculation
in the engine, you can get corrupted lightmaps. The problem affects
light when it’s built as something other than vanilla 32-bit
x86. (e.g. x86_64 on a mac).

The error message was actually displaying the edge vector, which is
always going to be ~(0,0,0). Pass in the edge end points and then we
can display both the length of the edge and the location of one end
point.

We need to skip over the textures with missing data lumps in the BSP,
i.e. having data offset -1.

Colours need to be scaled correctly by the light intensity.
Thanks to Mechtech for reporting this issue.

To improve debug messages, save the line number of the faces as we
generate them and in the case of hull generation, save a pointer back
to the source brush.

Enables us to check if there is extra data on the same line, without
advancing the parser past the end of line.

Search the WADs for extra frames on any animated textures used and add
them to the bsp. This restores the old behaviour which was mistakenly
removed, but now we have the assurance that textures are added in
order and all lower numbered animation frames are added a warning is
printed if it is missing from the wad.

Turns out there are two types of "BSP2" format - one that I think was
created by MH and implemented in the RMQ project (this is the one I
implemented previously) and one by LordHavoc which exteneded the
coordinate limits beyond 32k, implemented in Darkplaces. The
Darkplaces version of BSP2 will get the name BSP2 and the RMQ version,
which is more limited, will get the name BSP2rmq.
qbsp will only create the BSP29 or BSP2 formats, but will cope with a
BSP2rmq format file for an -onlyents compile. The rest of the tools
can use any of the three formats.

Add BSP2 support to the remaining utils. Since these share the common
bspfile.[ch] files, it was more effort than is justifiable to break this
into multiple staged patches - so you just get this disgustingly big
commit instead. Here is basically what was done:
* Modify the bspdata_t struct with a union of the two bsp formats
* Modify the tools to use bsp2_t for all internal processing
* Split out the byte swapping routines for the different bsp data types
* Add simple (although verbose) code to convert bsp29 <-> bsp2
Hundreds of lines added to bspfile.c, but mostly trivial stuff. The tools
internally had little modification except to substitute the bsp2 type
names.

Transition all tools to access the BSP data via the bspdata struct instead
of the shared globals. Remove the compatibility code from bspfile which
copied the global values to/from the instanced bspdata struct.
Mostly the changes just involved passing along the bspdata struct to the
various functions which needed to reference the data. TraceLine and
MakeTNodes in light got some extra changes so that we cache the node
dplane pointer and remove the need to pass the bspdata struct to every
trace operation!

Avoids reference to global LightDataSize. Need to move writing the lit
file above the call to WriteBSPFile, since that will do the byte swapping.
