Add support functions for running hooks configurable in the notmuch config
file. The hooks will be run using system(1).
TODO:
* Move notmuch_run_hook() out of notmuch-new.c. It's there and static only
because the first user will be there.
* Consider merging this with the following patch, as this is slightly
artificial as it is.
