This commit adds an owner file in each of the component directories
for each framework. This allows for a simple script to parse
the contents of the files and generate, among other things, tables
to be used on the project's wiki page. Currently there are two
"fields" in the file, an owner and a status. A tool to parse
the files and generate tables for the wiki page will be added
in a subsequent commit.
@ggouaillardet identified that HAVE_ALIAS_ATTRIBUTE was not properly
being defined in the embedded libfabric. This is because the
embedded configury missed the test for it (i.e., the real configure.ac
for libfabric always defines HAVE_ALIAS_ATTRIBUTE to 0 or 1 -- we
didn't emulate that properly here in libfabric's configure.m4).
Also, fix some grammar and properly escape another AC_MSG_CHECKING
message in libfabric's configure.m4.
When configured --with-devel-headers, there's now 2 "osd.h" header
files in libfabric (in different dirs). Automake's "install" target
didn't like this, and errored out.
Since embedding libfabric is a temporary measure, just avoid the
problem by not installing any libfabric headers.
Add the functions that changed between BTL 2.0 and 3.0 into compat.h
and compat.c:
* module.btl_prepare_src: the signature and body of this method
changed between 2.0 and 3.0. However, the functions that this
method calls did *not* need to change, so they are copied over
wholesale (with the exception that they no longer accept the unused
`registration` parameter).
* module.btl_prepare_dst: this method does not exist in BTL 3.0.
* module.btl_put: the signature and body of this method changed
between 2.0 and 3.0.
The send inline optimization uses the btl_sendi function to achieve lower
latency and higher message rates. Before this commit BTLs were allowed to
assume the descriptor was non-NULL and were expected to return a valid
descriptor if the send could not be completed using btl_sendi. This
behavior was fine until the usage of btl_sendi was changed in ob1. This
commit allows the caller to specify NULL for the descriptor. The affected
btls have been updated to handle this case.

This commit adds an interface for btl's to export support for 64-bit atomic
operations on integers. BTL's that can support atomic operations should
implement these functions and set the appropriate btl_flags and btl_atomic_flags.
