Handles beveled walkways in telefragged.bsp which touch a wall along one edge, but don't split the wall.
Previously, the walkways were blocking most of the traces for the wall, messing up all of the wall sample points.
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.

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.

Simplify the code by removing the if (colored) conditionals from the
code path. CPU cost is insignificant compared to tracing the rays.
As before, only write the lit file if colored lights are detected or
the use explicity requests it.

The only thing used by log.c was the qboolean definition, so just use
stdbool internally instead.

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.

I'd like to be able to control visibility of the global bsp data as well
as having the ability to load two bsp files and do comparisons, etc. Set
up a structure to hold all the bsp data and a couple of helper functions
to enable a smooth transition for the utils.

Copylump now doesn't need the size passed in, just the type. Also, pass
the file header into CopyLump while we're at it.

Removes the MAX_MAP_ENTITIES and MAX_MAP_ENTSTRING limitations by
counting how much space we will need before parsing/writing.
Now that I look at it, I'm not sure why we should even be re-writing
the entity string in the new bsp file, but I'll leave that behaviour
alone... for now.

Makes minlight additive rather than just bringing low levels up to the
minimum. Not entirely identical to the bjp implementation as it seems to
treat local minlights in some strange ways, but in most cases the
behaviour should be identical.
Added missing help text for -anglescale|-anglesense parameters too.

Add the -soft command line option which implements post-processing on
the lightmap surface to blend adjacent samples together to smooth out
hard shadow lines.
