[PATCH] libosmocore[master]: Add release target to Makefile

[Max]

Hello Jenkins Builder,

I'd like you to reexamine a change.  Please visit

    https://gerrit.osmocom.org/3130

to look at the new patch set (#2).

Add release target to Makefile

Add simple helper target to automate following release steps:
* cleanup TODO-RELEASE
* update debian/changelog
* git commit and tag
* git tag sign

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/
