the infrastructure put in place to manage cuda buffers is actually
a lot more generic than just for cuda buffers. Specifically, we ca
reuse much of the code to implement the external32 data representation.
This commit converts the code from common_ompio_cuda* to
common_ompio_buffer*. There are just very few places where we actually need to keep the OPAL_CUDA_SUPPORT ifdef in place.

use an allocator to manage temporary buffers when copying
unmanaged data from GPU buffer to host. This is necessary,
since the buffers have to be pinned for better performance,
which is an expensive operation.

this commit adds the initial support for cuda buffers in ompio, for blocking
and non-blocking individual read and write operations.

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.
