lib-mail: Make sure mail_user_hash() won't return 0 as the hash. It doesn't seem to actually happen, but this makes sure of it.

lib: API change - var_expand*() now returns error string. This allows callers to fail properly if the format string is invalid.

global: Try to initialize var_expand_tab[] directly. This avoids accidents with the array numbering being wrong.

global: Use i_strchr_to_next() wherever useful.

Remove t_malloc in favour of t_malloc_no0 Using either t_malloc_no0 or t_malloc0 makes it clear whether the allocated memory is zeroed or not.

lib-mail: mail_user_hash() has now a faster code path for format=%Lu

Added director_username_hash setting to specify what part of the username is hashed. The default is "%u" meaning the full username. Another potentially useful value is "%d" for hashing only the domain (i.e. redirect users from the same domain always to same server so they can safely access each others' shared mailboxes).
