The Open MPI code base assumed that asprintf always behaved like
the FreeBSD variant, where ptr is set to NULL on error. However,
the C standard (and Linux) only guarantee that the return code will
be -1 on error and leave ptr undefined. Rather than fix all the
usage in the code, we use opal_asprintf() wrapper instead, which
guarantees the BSD-like behavior of ptr always being set to NULL.
In addition to being correct, this will fix many, many warnings
in the Open MPI code base.

Compiler warning that ret was used before it was assigned. Since this
part of the code is not performance-critical, just throw in an extra
assignment and be done with it.
OpenSHMEMspec 1.1 introduces a set of environment variables that allows users to configure the Open-SHMEM implementation, and receive information about the implementation.
- Add SMA_SYMMETRIC_SIZE - number of bytes to allocate for symmetric heap
- SHMEM_SYMMETRIC_HEAP_SIZE (Mellanox extension) is used by a user to provide a size of symmetric area. This change sets this env variable in case a user does not set this variable
directly.
