Subject: database: Abstract _filename_to_direntry from _add_message
X-Git-Tag: 0.1~190

database: Abstract _filename_to_direntry from _add_message

The code to map a filename to a direntry is something that we're going
to want in a future _remove_message function, so put it in a new
function _notmuch_database_filename_to_direntry .
