gcf2: transparently retry on missing OID
Since we only get OIDs from trusted local data sources
(over.sqlite3), we can safely retry within the -gcf2 process

invalid OIDs and triggering reopens.

Calling ->add_alternate won't pick up new additions to

gcf2: libgit2-based git cat-file alternative
Having tens of thousands of inboxes and associated git processes
won't work well, so we'll use libgit2 to access the object DB
directly. We only care about OID lookups and won't need to rely
on per-repo revision names or paths.
The Git::Raw XS package won't be used since its manpages don't
promise a stable API. Since we already use Inline::C and have
experience with I::C when it comes to compatibility, this only
introduces libgit2 itself as a source of new incompatibilities.
This also provides an excuse for me to writev(2) to reduce
syscalls, but liburing is on the horizon for next year.

doc: txt2pre: more manpage URLs
We host our own -imapd manpage, and we started using a few more
