Mainly tidy up long lines and rename dir/test variables to edgevec[2]
since these are the edge vectors we are testing the angles between.

Since 'w' is commonly used for a winding variable, this makes the code
harder to read. Use the name 'edge' instead for these tjunc local types.

Also do a quick sweep of the source and consistently use %d instead of
%i (no real difference, but just pick one).

Instead of just assuming that 9999 or similar is "big enough", use the
implementation defined type limits.

Fix numerous places where epsilons have been hard-coded, substituting one of
the defines from qbsp.h.
A couple of epsilons have actually been changed in this patch; the one used to
detect degenerate QuArK texture coordinates has been loosened (so the test is
actually a little more strict). The other is the test for flipped portals. If
my understanding is correct, then result would actually be < 0 if the portal
winding normal flipped, so this change _should_ be harmless.

Rather than using it's own type of winding, make face_t use the existing
winding_t struct to define it's edges. I tried dynamically allocating the
winding as needed, but it was a net performance loss (though much better for
memory usage). For now we'll just embed a winding_t struct inside face_t
instead.

Set the vec_t type to "double" using the DOUBLEVEC_T preproccessor define. Fix
up hard-coded usages of float in various places throughout the code. Note that
texinfo_t is an on-disk structure, so that needs to stay as float and we work
around incompatibilities with the vector functions using a temporary vec3_t.

Now that we're compiling as C code, the memory returned by AllocMem no longer
needs to be explicitly cast when assigning to our typed pointers.

More source mangling; run indent over the source files to make it more
consistent with the rest of my utils code. Remove any trailing whitespace
while we're at it.

Import QBSP sources from Greg Lewis' TreeQBSP version 1.62.

Thanks to Greg for allowing me to use his modified source code:

The files are unmodified from the originals, apart from lower-casing the
filenames and removing ASCII CR characters from end of lines.
