check for possibility of heap2heap copy was incorrect
in case when shared heaps have different virtual
addresses on same host.
It seems that ibv_exp_reg_mr() on CIB cards may return
different VAs for heap on same node. On CX3 addresses are
the same.

top_ompi_srcdir -> OMPI_TOP_SRCDIR
top_ompi_builddir -> OMPI_TOP_BUILDDIR
We also split the srcdir/builddir flags according to their local tree (e.g., OPAL_TOP_SRCDIR), and tied them all together in configure.ac. Renamed ompi_ignore and ompi_unignore to be opal_<foo> as these are agnostic markers.
Only thing left is ompilibdir being treated similar to what we dif for srcdir/builddir. Coming soon.

Using MAP_ANONYMOUS brings different interpretation of fd, offset arguuments of mmap()
Linux:
The mapping is not backed by any file; the fd and offset arguments are ignored.
Mac:
Map anonymous memory not associated with any specific file. The offset argument is
ignored. Mac OS X specific: the file descriptor used for creating MAP_ANON regions
can be used to pass some Mach VM flags, and can be specified as -1 if no such flags
are associated with the region
FreeBSD:
Map anonymous memory not associated with any specific file. The file
descriptor used for creating MAP_ANON must be -1. The offset argument must be 0.
