Merge r1061,r1062,r1063 from libarchive.googlecode.com:

Fix reading big-endian binary cpio archives, and add a test.
While I'm here, add a note about Solaris ACL extension for cpio,
which should be relatively straightforward to support.

Thanks to: Edward Napierala, who sent me a big-endian cpio archive
from a Solaris system he's been playing with.
Pointy hat: me
