Various changes.
Separate a few reusable components from XZ Utils specific code. The reusable code is now in "tuklib" modules. A few more could be separated still, e.g. bswap.h. Fix some bugs in lzmainfo. Fix physmem and cpucores code on OS/2. Thanks to Elbert Pol for help. Add OpenVMS support into physmem. Add a few #ifdefs to ease building XZ Utils on OpenVMS. Thanks to Jouk Jansen for the original patch.
