This is preferable to open-coding "newsgroup // inboxdir" everywhere.

...and mostly wired up for WWW, but requires manual config
editing atm.  Needs docs and tests, and IMAP support.

This will also form the basis of a mairix workalike client.

Not sure about the usability aspects, but I think this can
replace the need for per-inbox Xapian DBs and save a truckload
of disk space (and more importantly: cache space).  Per-inbox
over.sqlite3 remains required for compatibility with NNTP/IMAP
and existing WWW code.

I don't know if the command-line tool is going to be called
public-inbox-eindex or public-inbox-extindex, but probably the
latter...

"xindex" could be confusing, and "eindex" rhymes with "reindex"
which could also be confusing.  But I'm even more easily
confused than usual these days :x

Performance isn't great, it took 30+ hours to index my mirror of
lore on a SATA SSD, but the entire index is <200GB due to
deduplication between cross posts.  -compact isn't working with
these indices, yet, but will sometime...

More changes on the way, still trying fix my brain and get
through this year...
