05f86b5df7 osc-rdma: fix datatype lower bound errors in ompi_osc_rdma_master()
Instead of ompi_datatype_get_extent(), use ompi_datatype_get_true_extent()
to get the local and remote lower bound.  For derived types like
subarray, true_lb is the correct offset for RDMA operations.

cc863ff9fb osc-portals4: fix datatype errors in put()
Instead of ompi_datatype_get_extent(), use ompi_datatype_get_true_extent()
to get the origin and target lower bound.  For derived types like
subarray, true_lb is the correct offset for RDMA operations.  Also,
instead of the extent use the size of the datatype.

c536e11cf3 osc-portals4: fix offset bug in raccumulate()
This commit fixes a bug where the remote offset was used as both
the local and remote offset.

Thanks to @PDeveze for the patch.

f6f24a4f67 build: Custom libmpi(_FOO) name option in configure
* Add a configure time option to rename libmpi(_FOO).*
   - `--with-libmpi-name=STRING`
 * This commit only impacts the installed libraries.
   Internal, temporary libraries have not been renamed to limit the
   scope of the patch to only what is needed.

For example:
```shell
shell$ ./configure --with-libmpi-name=wookie
...
shell$ find . -name "libmpi*"
shell$ find . -name "libwookie*"
./lib/libwookie.so.0.0.0
./lib/libwookie.so.0
./lib/libwookie.so
./lib/libwookie.la
./lib/libwookie_mpifh.so.0.0.0
./lib/libwookie_mpifh.so.0
./lib/libwookie_mpifh.so

./lib/libwookie_usempi.so.0.0.0
./lib/libwookie_usempi.so.0

59bae1a330 osc/rdma: fix typo in compare-and-swap
This commit fixes a typo in compare-and-swap when retrieving the
memory region associated with a displacement. It was erroneously 8
bytes instead of the datatype size. This can cause an incorrect RMA
range error when the compare-and-swap is less than 4 bytes from the
end of the region.

Fixed open-mpi/ompi#2080

1ce5847e8b osc/rdma: add support for network AMOs
This commit adds support for using network AMOs for MPI_Accumulate,
MPI_Fetch_and_op, and MPI_Compare_and_swap. This support is only
enabled if the ompi_single_intrinsic info key is specified or the
acc_single_interinsic MCA variable is set. This configuration
indicates to this implementation that no long accumulates will be
performed since these do not currently mix with the AMO
implementation.

This commit also cleans up the code somwhat. This includes removing
unnecessary struct keywords where the type is also typedef'd.

cb1cb5ffed osc/pt2pt: do not use frag send to send lock request
This commit cleans up some code in the passive target path. The code
used the buffered frag control send path but it is more appropriate to
use the unbuffered one. This avoids checking structures that are
should not be in use in this path.

1ba03d38ec io/ompio: protect remaining functions in multi-threaded scenarios
protect the remaining functions where necessary by a mutex lock
to avoid problems in multi-threaded executions. Some functions
do not require that in my opinion, and I provided an explanation
in those cases.

e53de7ecbe osc/rdma: fix bug in dynamic memory window tracking code
This commit fixes an ordering bug in the code that keeps track of all
attached memory windows. The code is intended to keep the memory
regions sorted but was often inserting at the wrong index. Thanks to
Christoph Niethammer for reporting the issue. The reproducer will be
added to nightly MTT testing.

7af138f83b osc/pt2pt: fix possible race in peer locking
It is possible for another thread to process a lock ack before the
peer is set as locked. In this case either setting the locked or the
eager active flag might clobber the other thread. To address this the
flags have been made volatile and are set atomically. Since there is
no a opal_atomic_or or opal_atomic_and function just use cmpset for
now.

bc042259bc make initialization of the io framework thread safe.
Also, remove the lock/unlock in the file_open ompi-interface routines of romio314.
The global lock in the romio component does probably not work, it is easy to construct a testcase where two threads perform collective I/O operations on different file handles. With a global lock it is easy to deadlock. THe lock has to be at least on the file handle basis.

move the mutex to file/file.c to avoid duplicate symbol problem in file_open.c pfile_open.c
