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.

Few components had wrong mca variables registration procedure
List of them:
- atomic basic and mxm
- spml yoda and ikrit
Two mca variables as runtime_api_verbose and runtime_lock_recursive change
names to oshmem_api_verbose and oshmem_lock_recursive otherwise they
were not shown by oshmem_info tool.

Deadlock when using the shmem_collect32()/shmem_collect64() routines and any of the non-root PEs pass 0 as the number of elements.
Algorithm in _algorithm_central_collector() does use 0 as a special value, and thus does not break out of the loop.

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.
