this commit syncs ompio related directories in v4.1.x to master. The efforts to bring the lustre performance fixes and support for external32 data representation over were too overwhelming when dealing with every single pr individually.
There are a very few minor modification that had to be done for syncing:
- v4.1.x does not have opal/mutex.h
- v4.1.x does not have opal_atomic_int32_t datatype
- the io module structure has two fewer function pointers (related to info_set/get) compared to the version on master.
Tested so far with the ompio testsuite as well as hdf5-1.10.5 testsuite (testphdf5, t_shapesame, t_bigio) on an XFS file system.
More tests on Lustre and BeeGFS to follow.

since the request code is now being accessed also from the vulcan fcoll
component, the request code was relocated into the common/ompio
directory to avoid ld load problems.

Rewrite the ompi_request_complete function to take in account the
with_signal argument. Change the comment to explain the expected
behavior.
Alter all the ompi_request_complete uses to make sure the status of the
request is set before calling ompi_request_complete.
