Granger for bringing this to our attention.
This needs to be modified slightly to go to the v1.0 branch. Will
submit patch via e-mail.

the code to use the new PML send flags.

* Implement fortran handle -> c handle tracking
* Remove some unneeded locking around free lists (the free list
macros do their own locking)
* Try to be a bit more memory friendly with the w_mode setting /
checking

a subset of win's group, so this should never happen. But users have
been known to screw up before, so return a reasonable error.

some point, I realized having a variable name "new" might cause some
problems for those people using a C++ compiler to compile C code ;).

complete, but stable enough that it will have no impact on general development,
so into the trunk it goes. Changes in this commit include:
- Remove the --with option for disabling MPI-2 onesided support. It
complicated code, and has no real reason for existing
- add a framework osc (OneSided Communication) for encapsulating
all the MPI-2 onesided functionality
- Modify the MPI interface functions for the MPI-2 onesided chapter
to properly call the underlying framework and do the required
error checking
- Created an osc component pt2pt, which is layered over the BML/BTL
for communication (although it also uses the PML for long message
transfers). Currently, all support functions, all communication
functions (Put, Get, Accumulate), and the Fence synchronization
function are implemented. The PWSC active synchronization
functions and Lock/Unlock passive synchronization functions are
still not implemented

It's still not very clean as we still lock the mvapi_btl mutex inside a critical section
protected by the endpoint mutex ...

- Remove printing of CFLAGS in configure.m4
- Set MCA_BTL_FLAGS_SEND flag
- Improved error handling during module initialization
- Extract the address of each interface with dat_ia_query
- Start playing around with fragment stuff - probably wrong
- Misc code cleanup (removal of GM-specific code)

at all for anyone (other than running autogen, of course)

know that the request is inactive we don't have to call fini). Remove if's from
the critical path. Change a do in while to make sure we do the minimum in all cases.
All in all it decrease the latency for mvapi by something between 0.15 and 0.20
micro-seconds. But it's just a first step ...

increased the datatype ref count, and there is no way to have a convertor without a valid
request, so there is no need for the convertor to increase the reference count of the datatype
again. Therefore, if one want to use the datatype for something else than MPI request, one
has to manage the reference counts outside the datatype layer.

thread finish a request between the moment when we check the request status and the moment
when we acquire the lock, and if there are no more pending request on the pipe we will be
stuck foreverr as nobody have any reason to broadcast the request condition. I check the
req_any and it doesn't contain the same bug.

the descriptors to vanish. The PML was thinking that they are in the btl_cache when they
weren't ... It lead to memory consumption on most environments when compiled with
thread enabled. After modification the latency went down by nearly 0.5 microseconds.
Simple way to trigger the bug: limit the number of maximum items in the free list and run
any communication intensive application (like Netpipe).
