[notmuch] [PATCH 3/3] notmuch-show.c: prototype tabular output format, with output control

From: David Bremner <bremner at unb.ca>
Currently this only outputs the information from the "message header";
i.e. the part before the rfc2822 header or body.
Adding this required adding an extra parameter, currently unused, to
format_message_text and format_message_json. Also the struct
definition is changed to match the new function prototypes.
An int (enum) is used as a mask, each bit corresponds to some part to
be shown or not shown. This enum will need to be extended as more
things are controllable via --show.
