  lib-storage: Don't stop vsize calculation on expunged mails.

I don't know why I added such logic there in the first place. If we just
skip the expunged mails, the end result should still be correct and
usable when cached.

  Log Message:
  -----------
  lib-storage: Add mail_vsize_bg_after_count setting.

If folder vsize calculation requires opening more than this many mails from
disk (i.e. mail sizes aren't in cache already), return failure and finish
the calculation via indexer process.

This should be used like:

protocol !indexer-worker {
  mail_vsize_bg_after_count = 10
}

  Log Message:
  -----------
  lib-storage: Update vsize header after sync only if sizes are cached.

The result isn't needed yet in that case, so if it's slow to get the sizes
it might as well be delayd until later. This is especially useful when
indexer-worker triggers FTS indexing. The vsizes can be added to index
after the mail is already read for FTS. Without this change the vsize
update would first open all the mails and then the FTS indexing would
open all the mails a second time.
