Makefile: complicate version detection script

Browse source 
We've declared that we are using semantic versioning. We also want to use `git
describe` to make version strings for us because it's very convenient for
development builds (tagged versions are way simpler). The problem is that the
default `git describe` behavior is not semver compliant. If the most recent
tag is v0.99.2 then it'll generate something like '0.99.2-131-g8dc5b385',
which according to semver is a development version _before_ 0.99.2. While it's
obviously a version _after_ 0.99.2.

That's the one and only reason we have vX.Y.Z-pre tags in our repo. We set
them right after the release according to the release process and that gives
us some '0.99.3-pre-131-g8dc5b385' versions we're all used to. But these tags
are ugly as hell and they clutter up our repo over time.

So there is this idea that we can do patch version increment dynamically.
Making '0.99.2-131-g8dc5b385' be '0.99.3-pre-131-g8dc5b385' without any *-pre
tags. This patch implements this. It's ugly as hell as well, but at least
that's an ugliness somewhere inside our Makefile and not directly visible in
our tags. If we're to do this we can then greatly simplify our release process
(and even allow for CHANGELOG patches to be merged normally).

I know this can be done with awk in somewhat easier way, but no, I'm not into
awk, sorry.
