it now handles more than just git, and i forsee
it handling even more in the future, e.g. rsync,
ftp, bittorrent.

Don't leave a broken cache laying around, which would
otherwise break lbmk for the user.

And this time it works.

I'm now calling xbmkget() which in turn calls tmpclone(),
instead of me calling tmpclone() directly.

The git-pull is done on both remotes, regardless of whether
the first succeeds. This way, if I forgot to update a mirror,
downloads would probably still work.

This also fixes an issue people were having, for example where
the gnulib repository of GRUB was always being downloaded
every time.

I'm using a new directory, XBMK_CACHE/clone, instead
of XBMK_CACHE/repo (which I used before), in case people
still have the old caches from before.

We don't need to call it from git.sh, because it's
only being done when building a release anyway,
and we already run rmgit when doing a release.

The function itself is only two simple fx_ calls,
so we can just do that from build_release().

in cbmk, it's only used from there.

in lbmk, it's also used from vendor.sh.

however, i plan to further expand git.sh at
some point, tidying it up so that git cloning
is also done from xbmkget, with dlop=git and
git.sh would then be renamed to get.sh

many places in lbmk used err, because older versions
of x_ did not handle globbing properly.

however, use of x_ is preferable on trivial commands.

the only time err() should be called is what it has
to be, when x_ can't work, or when a more useful error
message is needed, for context.

remove caching for now. it's buggy as hell.

will re-write the caching feature next.

similar to the last patch, we must ensure that the
inability to patch will cause a hard exit, regardless
of any redundancy we have for cloning.
