We should update $GIT_DIR/info/refs for dumb HTTP clients
whenever we make changes to the repository. The best place
to update is immediately after making commits.
This fixes a bug where public-inbox-learn did not properly
update $GIT_DIR/info/refs after inserting or removing
messages.

This is used all over the place, but may not be in the future,

remove GIT_DIR env usage in favor of --git-dir
No need to maintain per-block environment state when we can
localize it to per-command. We've had --git-dir= in git
since 1.4.2 (2006-08-12) and already use it all over the
place.

remove ssoma dependency
By converting to using ourt git-fast-import-based Import

nntp: reduce timers for weakening
Danga::Socket timers are not cheap, so avoid creating up
to 3 timers per-newsgroup by batching resource weakening.
This lets us reduce resource consumption for scheduing
additional resource consumption reduction :)

split out NNTPD and HTTPD* modules
Hopefully this modularizes things a little and allows us

view: show flat thread view in chronological order
Allowing readers new to a topic to follow in chronological order
probably makes the most sense. Reverse chronological order may
reduce scrolling (e.g. log view); but nearly all non-threaded
conversation displays seem to be chronological so perhaps
there's a good reason for that.
