MDLSITE-3252 check for third party library modifications

This check will try and find modification to third party libraries
and warn about them if the thirdpartylibs.xml or readme_moodle.txt has
not been updated.

MDLSITE-3252 check for third party library modifications
MDLSITE-2712 allow checks against integration
MDLSITE-2712 tidying, commenting and reorganizing a bit

This change contains basically cosmetic changes only to
comments, initial creation of integration.git remote and
tidying exit-on-error.

The only remarkable change is that, now, the ancestor to be
used is calculated (using the same way it was previously) and
only then all the checks begin (including the branch aging ones
that previously were executed always for the moodle.git ancestor).
