[PATCH] devel: add release-checks.sh

[Tomi Ollila]

Currently Makefile.local contains some machine executable release
checking functionality. This is unnecessarily complex way to do it:

Multiline script functionality is hard to embed -- from Makefile point
of view there is just one line split using backslashes and every line
ends with ';'. It is hard to maintain such "scripts" when it gets longer.

The script does not fail as robust as separate script; set -eu could
be added to get same level of robustness -- but the provided Bourne
Again Shell (bash) script exceeds this with 'set -o pipefail', making
script to fail when any of the commands in pipeline fails (i.e. not
just the last one).

Checking for release is done very seldom compared to all other use;
The whole Makefile.local gets simpler and easier to grasp when most
release checking targets are removed.

When release checking is done, the steps are executed sequentially;
nothing is allowed to be skipped due to some satisfied dependency.
---

I did not send patch to remove corresponding lines from Makefile.local
just yet. This allows David to run this script in parallel to the code
currently in Makefile.local -- and make sure 0.14 gets best release
engineering treatment so far. Then Makefile.local can be made to execute
this script in place of code it supersedes.
