caught by clang's -fsanitize=shift. A small unsigned int was
promoted, according to C's regular promotion rules, to a signed
int, it was then left shifted. This sometimes pushed a 1 into
the sign bit, which is undefined behaviour. Fixed by using
unsigned temporaries.
Make changes equivalent to those originally made by commits
bd56626a (Fixes for the OSF operating system build, 2010-09-08)
92c082b1 (Add a fix for the inline keyword on the osf os, 2010-09-10)
but based on the updated libarchive snapshot.
This allows for a built in bzip and zip capability, so external tools
will not be needed for these packagers. The cmake -E tar xf should be
able to handle all compression types now as well.
