lib-index: Avoid writing tail offset update to transaction log if it's not necessary.
This should avoid extra writes that do nothing but update the tail offset.
mdbox's map requires this behavior, so disable it for it. For others it
might cause the next sync to read more data unnecessarily, but it should be
worth the extra cost of write most of the times.

indexer: Improved handling multiple indexing requests to the same mailbox.
If a request arrives for a mailbox that we were already indexes, the
previous code simply sent the indexing request to the existing worker
process. This could have caused a lot of requests to be buffered to the same
mailbox if the indexing took a long time, which could have taken a while to
process even though they weren't really doing anything indexing work.
The new code instead just keeps track in memory that when the earlier
indexing is finished, it's done again once to finish any pending changes.

lib: API change - have uni_utf8_get_char*() return _char_bytes
Often the two functions are called in close proximity (both ways round). As
_get_char*() calls _char_bytes() early on the success path, we may as well
return that value to the caller for immediate use.
The callers which call _char_bytes() first are simply rejecting the truncated
case quickly - all other invalid cases still call both functions, and all
other valid cases (which should be the fast path) likewise call both.

If the token is truncated, we don't want to remove the trailing character
