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.

Make CheckStack return an error code if we have recursed and print
some information about the offending leaf/portals before continuing.

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

Just in case unsigned long isn't big enough to capture the pointer
offsets. Also, cast STACK_WINDINGS to the correct type before doing the
comparison.

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.

First pass at detail support as implemented in tyr-qbsp, using the PRT2
file format (hopefully nobody else already decided to use that?)
Because the "leaf" terminology is pervasive across the source, I've left
it there for now (so "leaf" usually now means "cluster") and added a few
variables with the "_real" suffix when they actually mean the real leafs
and not the clusters which vis still calls leafs. A bit disgusting, but it
actually works so I'll go through and clean up naming, etc. later.

Inspired by the implementation of Benjt Jardrup, save the current state of
the vis job to disc at regular intervals so that we can resume from that
point in case the computer needs to be rebooted/shutdown or crash/power
issues occur.
