[PATCH] build: extract library versions from notmuch.h

- Make lib/notmuch.h the canonical location for the library versioning
information.
- Since the release-check should never fail now, remove it to reduce
complexity.
- Make the version numbers in notmuch.h consistent with the (now
deleted) ones in lib/Makefile.local
---
Not counting turning 20 lines of lib/Makefile.local into a template in
configure, the main change here is replacing a test in
release-checks.sh with another piece of code in configure. This isn't
obviously a good idea, since everyone has to run configure and few run
release-checks. Personally, I think the test in config is a bit
cleaner, but the main point is that it is much nicer to have the
version information only in one place.
