This is a change from taking a vector containing the mapping to
deck-consistent logical cartesian indices. The mapping is contained
in the UnstructuredGrid::global_cell member, and may be null. The
change therefore saves the overhead of constructing a vector as a
copy of the data in the grid or (if null) as an identity mapping.
Now we may have a grid generated from deck input using the
keywords DXV, DYV, DZV, which will have a null pointer for
the global_cell mapping. We check if this pointer is null,
and create an identity mapping in this case. The mapping is
needed by the *PropertiesFromDeck classes (and helpers).
Apparently, Automakes prior to 1.10 do not automatically substitute
the absolute path directory variables
abs_srcdir abs_top_srcdir
abs_builddir abs_top_builddir
that Autoconf computes (since ca. 2003) into the Makefiles. This
leads to a subtle error when OPM-Core is used in conjunction with
dune-common's DUNE_CHECK_MODULES (or, more appropriately, our own
OPM_CORE_CHECK_MODULES) macro that gets invoked through dunecontrol.
The *_CHECK_MOUDLES macro contains an unconditional statement that
uses 'abs_top_srcdir' to compute the absolute path to the current
module's top source directory. When abs_top_srcdir is unset, the
root becomes unset too, whence the subsequent existence and validity
checks fail due to incorrect CPPFLAGS and/or LDFLAGS. It will also
fail to locate the 'dune.module' dependency file.
By explicitly substituting the above variables into the Makefiles,
as was also done in revisions 5819 and 5845 of dune-common's
Subversion repository, we're guarding against this particular
failure mode.
Tested on: CentOS 5.8 (Autoconf 2.59, Automake 1.9.6)
