compute the hetero flag a little bit different. The hetero flag is now
attached to a convertor if and only if we can use the optimized conversion
functions. It's a little bit broader than before (the 2 architectures
has to be identical).
This commit was SVN r11962.
First, move the OPAL_THREAD_LOCK out to the same level as its corresponding UNLOCK. It was possible to hit the UNLOCK without ever acquiring the lock.
Since the OPAL_THREAD_ADD64() is now protected by this lock, we can just do the decrement non-atomically.
This commit was SVN r11958.
Don't try to acquire ompi_request_lock here, which in all cases is already held. Avoids deadlock that occurs even when threads are enabled and we're running a THREAD_SINGLE app.

conversion function are more complex and costly than a simple memcpy. Therefore,
we want to decrease as much as possible the usage of these functions.
We now check not only th HOMOGENEOUS flag on the datatype or convertor, but the
bits indicating a type is in use. If a communication transfert a type having the
same representation on both peers we can use the optimized version of the conversion.
In same time we build a more accurate conversion table for each master convertor,
based on the minimum differences between the 2 architectures.

I have added a new MCA param (hey, you can't have too many!) called OMPI_MCA_orte_timing. If set to anything other than zero, the system will report out critical timing loops. At the moment, this includes three measurements:
1. Time spent going through the RDS->RAS->RMAPS, setting up triggers, etc. prior to calling the actual PLS launch function. This is reported out as time to setup job.
2. Time spent in MPI_Init from start of that function (well, right after opal_init) to the place where we send all of our info the registry. Reported out as time from start to exec_compound_cmd
3. Time actually spent executing the compound cmd. Reported out as time to exec_compound_cmd.
A few additional timing points will be added shortly.
These may eventually be removed or (better) setup with a conditional compile flag.
