[mms] Fix EOL filter when multi-character EOL is split between incoming buckets (Bug #12673).
Make more methods abstract.

The implementation in the base method was PDO-specific anyway.
Already defined in base class.
[jan] Always return a Horde_Db_Adapter_Base_Result sub-class from the select() method.
AVoid strict error.
execute() won't go completely, just don't use it.
Fix incorrect usage of Horde_Db API.

The code was assuming select() would return a PDOStatement, but it will only
guarantee to return a Traversable (or Horde_Db_Adapter_Base_Result after my
refactoring).
Fix message actions in minimal view
Improved error notification messages
[mms] Fixed regression in enforcing max_recipients and max_timelimit permissions (Bug #12674).
Cast these values to integers
Don't wrap ngettext strings in an additional gettext call
