The patch that was previously fetched from GitHub is now part of the
4.5.1 release, and is no longer needed. Furthermore, 4.5.1 introduces
some new scripts to build manpages, and some new build inputs are
required to make that work.
This also rebases the Darwin patch. I don't have a Mac so I can't test
this personally. There was one conflict:

Resolved by updating the signature from int to long long.
I pretty much manually applied all the changes in the patch to the new codebase and then generated a new diff because the pull request mentioned at the top of the patch was not accepted and will probably never be updated again.
This new patch is the patch between 4.4, and commit [1], a pull request
at [2] to upsteam Mac and BSD compatibility. That pull request is
itself a rebase of an older pull request for an earlier version of
squashfs-tools. I squashed all commits between 4.4 and [1], apart from
the BSD-specific ones, and exported the new patch from that. Attached
below is the git diff --ignore-space-change between squashfs-tools 4.4
with the previous patch applied, and with the new patch applied.

I took the patch, and applied it on top of the previous squashfs-tools
commit that we packaged. It applied cleanly. Then I rebased that on top
of master, and resolved the conflicts. I'm not sure I resolved them
correctly though, I don't have access to Darwin. Somebody needs to
review this.
