Moving these functions to libnotmuch_util will allow re-user from
either multiple CLI compilation units or from the library. To avoid
future surprises, replace printing to stderr with the usual status
string mechanism.

To: notmuch
This is closely based on git-remote-nm (in ruby) by Felipe Contreras.
Initially just implement the commands 'capabilites' and 'list'. This
isn't enough to do anything useful so start some unit tests. Testing
of URL passing will be done after clone (import command) support is
added.

Apologies for the lack of subject. Still caffeine deficient this

The other thing it makes me think is that GLib is arguably badly
re-inventing C++, so that's something to ponder. I don't know if argues
for just using C++, or for going the extra mile and using talloc.

9) I replaced the shelling out to "git var" with interrogating the
notmuch configuration database. The behaviour is slightly different, in
particular GIT_COMMITTER_* environment variables are currently
ignored. Obeying those could be added fairly simply, I think. There are
probably other subtlties to how git constructs GIT_COMMITTER_IDENT; I'm
not sure if those are important.
10) I observed there are still a few relics of the "git-remote-nm" name
in the code.
11) I think this should eventually save and restore configuration
information and properties like dump / restore do. I don't see any
conceptual barrier to doing so, just more code.
