Merged in changes from Orange-Branch. There were a number of bugs fixed there since this branch was created.

merging Orange Branch changes in

initial merge with Orange-Branch. much will be broken

merge of B2O-Blue-Sync,HEAD,and latest of Orange.

merging bmi-experimental-branch to trunk

commiting changes from merge of Orange and Blue into test branch.

unexpected msg class support in bmi_mx; untested.  Uses 8 remaining bits in
match info.

merge from HEAD: http://www.pvfs.org/fisheye/changelog/PVFS/?cs=MAIN:atchley:20090727142649

* Replaces unex_txs queue & lock with a done_q & lock for each context
  These queues hold completed expected msgs (rx and tx) as well
  as completed unexpected sends per context. This is what was missing
  and caused the errors. Reported by Kazuki Ohta.

* Adds the completion lock and reference count to serialize accesses
  to MX completion functions to prevent races between BMI_test(),
  BMI_cancel(), BMI_testcontext() and BMI_testunexpected(). These
  now call get_completion_token() and release_completion_token().

* Add bmi_error_code_t to msg context (struct bmx_ctx) to store the
  BMI error code rather than rely on the MX status code which is not
  set in BMI_cancel(), for example.

* Added deq_unex_rx() to return a completed unexpected recv if available.

* Added q_completed() to queue completed messages on the appropriate
  done_q or unexpected rx queue. It stores the MX status and BMI
  error.

* Added deq_completed() to return a completed expected msg or completed
  unexpected send.

* Added complete_ctx() which assigns the out variables and does cleanup.
  This reduces code duplication in BMI_test() and BMI_testcontext().

* Remove unused functions: deq_ctx(), q_unex_ctx(), q_canceled_ctx()

* Combined put_idle_[rx|tx]() into put_idle_ctx()

* Eliminate bmi_mx specific logging (keeps PINT_EVENT_*)

Added.

Updated branch with code from HEAD

Replace enter and exit debug with macros. Add to more functions

Revert default debug output to ERR and WARN only

syncing small-file-branch back up with trunk at small-file-branch-point2 tag
(reverse merge)

merge a bunch of fixes made to HEAD since 2.7.0.

Enable server-to-server communications. This patch replaces some magic numbers
with macros, uses the MX session number returned from mx_decompose_endpoint_addr2
to determine is a CONN_REQ requires canceling pending rxs, etc., eliminates
checks to prevent servers from acting as clients, and adds completion queues
for unexpected txs and rxs reaped in the wrong functions (txs in testunexpected
and rxs in testcontext).

Modified Files:
	mx.c mx.h
	Add static before each function
	change struct method_addr to struct bmi_method_addr where used

Modified Files:
	mx.c mx.h
	Handle bmi_method_addr_forget_callback() properly

Modified Files:
	mx.c mx.h
	Define BMX_MASK as ~0ULL and replace -1ULL with it

Modified Files:
	mx.h

	Reapply Pete's last change

Modified Files:
	mx.c mx.h

	Sync with Myricom's svn HEAD

	Increase unexpected messages size from 4KB to 8KB to handle small IO
	Increase large IO buffer size from 1MB to 4MB
	Add buffer handling for unexpected messages to remove malloc for
	    unexpected messages
	Improve error reporting and use BMI errnos
	Move completion of unexpected sends after expected sends/recvs

Always define gossip_backtrace(), just as a noop if it cannot be built.  This
simplifies some ifdef nests in a few spots.  No behavior change.

Merge HEAD changes to TAS-branch.

walt3 reverse merge from head includes merges of pw's sm changes (no state declarations), cleanup of state machine code, and other general merging/fixes.

Update migration branch to current CVS version

add COPYING bits to mx header.

Initial commit of BMI MX implementation provided by Scott and Myricom.  Thanks Scott!
