Subject: [PATCH] create notmuch_show_params_t structure for holding parameters
 passed to show functions.

This simplifies the passing of arguments to the show functions.  This
will be very useful as we accumulate more parameters that will need to
be passed.  Currently only the entire_thread parameter is passed this
way.
