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

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!

Rename the default bsp29 data types and add the bsp2 data types to
the common bspfile.h. Propogate the bsp29 names into the other tools as
simple renames for now.

First pass, checks most of the data structures actually reference within
the valid ranges. Will add more soon...

No longer update the globals in this function - make the callers do it
instead.
bspinfo no longer refers to the globals at all.

Just having one base pointer was kind of annoying because you have to cast
to get to the lump offsets, then cast to byte * to find the miptex, etc.
Now we can access the same pointer using the correct types in each case.

Add the ability to extract texture information from a BSP file and write it
out as a WAD file. Not very robust in the face of errors or corrupt BSP files,
but it does the job for now.
