Here is a (very early version) of an async notmuch-pick based on the
above idea. This is on top of the previous patch series. There are two
attached patches: the first is a very small patch to notmuch-show.c to
print newlines between threads (since this is sufficient framing for
notmuch-pick; obviously it does not help notmuch-show at all).

The second patch implements the async handling in notmuch-pick.el. This
is probably very inefficient, and doubtless has significant bugs, but it
seems to mostly work and does display the first page of results almost
immediately even on very large queries so I think this is the right way
to go.

I am mostly posting it so people can play with the functionality but
cleanups, bugfixes, bug reports etc are gratefully received!

Best wishes

Mark
