This allows a single cat-file-like process to handle multiple
inboxes; instead of having a "git cat-file --batch" process for
every inbox; saving pipes and process table space.

The preliminary code was done months ago, but I struggled to put
all the pieces together in a coherent way.  My brain has been
scattered :x

I finally decided to make the gcf2 process a global singleton
(per-worker) to avoid complexity elsewhere in the config...

It doesn't detect or release unlinked packs + indices, yet,
so "git gc" may not free disk space until restarted.

Otherwise it does detect new epochs and seems mostly working
otherwise...

  gcf2: libgit2-based git cat-file alternative
  t/gcf2: test changes to alternates
  add gcf2 client and executable script
  gcf2: transparently retry on missing OID
  gcf2*: more descriptive package descriptions
  gcf2: require git dir with OID
  gcf2: wire up read-only daemons and rm -gcf2 script
