Roland Kaufmann 6e2084cf15 Safe-guard against version mismatch
The version declared for the build system (in dune.module) is checked
against what is in the source (e.g. opm/core/version.h) and if these
don't match, then issue an author warning.

This will help us keep the two version numbers in sync., since it
becomes very obvious when we don't. The benefit for this is to not have
the build system start mucking with the code just to dump some static
information in there.

# - Write version information into the source code

# Add an unconditional target to the Makefile which checks the current
# SHA of the source directory and write to a header file if and *only*
# if this has changed (thus we avoid unnecessary rebuilds). By having
# this in the Makefile, we get updated version information even though
# we haven't done any reconfiguring.
#
# The time it takes to probe the VCS for this information and write it
# to the miniature file in negligable.
#
# If the build type is Debug, then we only write a static version
# information as it gets tiresome to rebuild the project everytime one
# makes changes to any of the unit tests.
