searchidx: make v1 indexing closer to v2

We'll switch to using IdxStack here to ensure we get repeatable
results and ascending THREADIDs according to git chronology.
This means we'll need a two-pass reindex to index existing
messages before indexing new messages.

Since we no longer have a long-lived git-log process, we don't
have to worry about old Xapian referencing the git-log pipe
w/o FD_CLOEXEC, either.
