checkvintf: checks compatibility between files

checkvintf is a host binary that checks compatibility
between a manifest and a matrix.

Example usage:
$ checkvintf system/libhidl/manifest.xml \
  device/foo/bar/compatibility_matrix.xml

If compatible, write "true\n" to stdout and exit status = 0.
If incompatible, write "false\n" to stdout, write
   error message to stderr, and exit status = 1.
If I/O error or parse error, write error message to
   stderr and exit status = -1.
