• fixed the last remaining cache corruption problems (I hope, no known ones left)
• internaldate was never read from cache, but it was always cached again. this grew cache file uselessly and triggered cache compression constantly
• buffer_set_used_size() assertfixes with mmap_no_write=yes (although it hasn't been much tested since the recent large index file changes, hopefully works..)
• POP3: Replaced timestamp in APOP challenge string with 128 bits of base64d randomness
• Added pop3_enable_last setting to enable LAST command
