xmh: update to 1.0.5.

This release adds -help & -version options, and has a number of
code cleanups.

For those building for 32-bit platforms, it also enables use of the
"large file" APIs - while files handled by xmh should rarely be more
than 2gb in size, they may be stored on filesystems with large inodes.

Since this release was generated using the new GNU autoconf 2.72, this
also adds a --enable-year2038 configure flag which may allow xmh to
work with files whose timestamps are later than January 19, 2038, but
this has not been tested.
