  lib-index: Add mail_cache_close_mail() to smartly drop cached data with INDEX=MEMORY

Instead of reseting the entire transaction buffer when 256 kB is reached,
just drop mails have have been marked closed with mail_cache_close_mail().
If that's not enough, continue deleting forcibly until the buffer is below
256 kB.

This is especially important when mail_prefetch_count>0 and INDEX=MEMORY.
In that case there can be multiple mails that are being added to cache
and used later on. If they were dropped from cache too early, the work
would have to be done all over again.
