1. tectonic: clean up xeq_level …

   This macro was being used in a gross way to hide an offset in the array
   indexing. Make it a bit clearer what's going on, and importantly change some
   magic hardcoded numbers into symbolic constants. Also fix an off-by-one in the
   size that was exposed in the port to Winows.

2. tectonic: avoid Unix-specific headers for the Windows build …

   Could probably remove some of these #includes outright, but at the moment it's
   easier just to #ifdef them.

3. build.rs: adapt so that we can build on Windows (!) …

   In particular, on Windows we force static linking, since the DLL loading story
   is *gross*.

5. src/io/local_cache.rs: fix this on Windows …

   First, there's a quirk about file locking that we need to work around. Second,
   we need to add a racy check to the code that saves files under their MD5sum
   names, since on Windows we can't rename one file onto another file that's
   read-only.

6. tectonic/dpx-pdffont.c: getenv() doesn't do the job on Windows …

   Windows provides a getenv() call but it seems that it only looks at
   libc-internal data structures, such that we don't see the values of
   environment variables changed at runtime through Rust. This breaks the test
   suite. So, use GetEnvironmentVariable instead.

7. tectonic/dpx-dpxfile.c: make tempfile creation work on Windows …

   Of course, all file I/O should be going through Rust, so *really* we should be
   ripping this code out. But I want to get us working on Windows and this seems
   like the fastest path forward.

8. tectonic/dpx-dpxfile.c: rip out some cache code for Windows …

   This is more code that should probably disappear anyway -- I think it only
   exists for shelling out to Ghostscript and other stuff along those lines that
   we definitely don't want to do in Tectonic. It used <dirent.h> and so was
   going to be annoying to compile on Windows, so, sayonara.

9. tectonic/dpx-spc_dvips.c: rip out calculate_PS for Windows …

   This shelled out to Ghostscript to calculate bounding boxes or something.
   There's no way we wanted to do that anyway, so kill the code. It wouldn't
   build on Windows due to the use of popen().
