Convert compression_skip from taking a size_t skip length request and
returning the length skipped in a ssize_t to using off_t for both.  This
does not break any A[BP]Is, since compression_skip is entirely internal
to libarchive.

If a skip request is > SSIZE_MAX, don't pass it down to the client layer
skip function, since those still uses size_t / ssize_t.  Instead, just
read the data and throw it away.

With this commit, libarchive/bsdtar should now successfully skip archive
entries of >2GB on 32-bit systems, but does so slower than necessary.
The performance will improve with a future A[BP]I breaking commit which
makes client layer skip functions use off_t.

Discussed with:	kientzle
MFC after:	1 week
