Subject: Add release target to Makefile

Add simple helper target to automate basic release steps:
* version bump
* prepare release commit
* git commit, tag and sign

For library projects:
* update debian/changelog from TODO-RELEASE
* cleanup TODO-RELEASE

For non-library projects:
* update debian/changelog from git log

Note: it requires bumpversion package to be installed, debian/control is
adjusted accordingly. The helper itself is installed to facilitate reuse
by other libraries.

N. B: you still have to manually adjust LIBVERSION in previous commit -
see TODO-RELEASE header for details.

Use it as follows:
make REL=minor release

The REL parameter defines which component of the version [1] to bump and
can be any of { major, minor, patch }.

[1] http://semver.org/
