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!

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.

Importing parts of this from TyrQuake - means that the base type used for
managing the bit vectors is unsigned long. Not really a performance win or
anything here, just a bit nicer to not have to cast from (byte *) to
(long *) - just adds a little extra work before writing out the compressed
data.
