From: David Bremner <bremner at unb.ca>
This commit adds argument handling from and callbacks to
notmuch-output.c to determine what headers to show in json output.
This requires passing a pointer to a struct containing the output
parameters into several functions, and in particular changes the type of
the function pointers in the show_format structure.
