The V2Writable object may be long-lived, so it makes more
sense to put the {autime} and {cotime} fields into the
shorter-lived index_sync state.

--rethread and --no-sync options are now supported in
public-inbox-index.  --no-sync should be nice for users
of FSes with poor fsync(2) performance.

Now: I also wonder if --no-sync is a bad name since we
also use it for to mean synchronising indices.  Perhaps
--no-fsync would be a better name, though technically
SQLite and Xapian use fdatasync(2), nowadays.

Some of this is prep work for exposing THREADID via IMAP (and
JMAP) to aid in searching.

Since THREADID (`over.tid') will be exposed in a user-visible
way, I'm finally giving up on using the default (reverse
chronological) log order for indexing to ensure THREADID
ascends for newer threads.

This also simplifies the indexing code significantly.
To avoid pinning huge amounts of RAM, the working space is held
in a IdxStack temporary file.  This further simplifies our code
since we no longer have to worry about old that did not use
Xapian w/o FD_CLOEXEC.

There's still more work on the horizon, here...

Eric Wong (20):
  index: support --rethread switch to fix old indices
  v2: index forwards (via `git log --reverse')
  v2writable: introduce idx_stack
  v2writable: index_sync: reduce fill_alternates calls
  v2writable: move {autime} and {cotime} into $sync state
  v2writable: allow >= 40 byte git object IDs
  v2writable: drop "EPOCH.git indexing $RANGE" progress message
  use consistent {ibx} field for writable code paths
  search: avoid copying {inboxdir}
  v2writable: use read-only PublicInbox::Git for cat_file
  v2writable: get rid of {reindex_pipe} field
  v2writable: clarify "epoch" for {last_commits}
  xapcmd: set {from} properly for v1 inboxes
  searchidx: rename _xdb_{acquire,release} => idx_
  searchidx: make v1 indexing closer to v2
  index+xcpdb: support --no-sync flag
  v2writable: share log2stack code with v1
  searchidx: support async git check
  searchidx: $batch_cb => v1_checkpoint
  v2writable: {unindexed} belongs in $sync state
