callbacks to be triggered when memory is about to leave the current
process. The system is designed to allow a variety of interfaces,
hopefully including whole-sale replacement of the memory manager,
ld preload tricks, and hooks into the system memory manager. Since
some of these may or may not be available at runtime and we won't know
until runtime, there is a query funtion to look for availability of
such a setup.
* Added ptmalloc2 memory manager replacement code. Not turned on by
default, can be enabled with --with-memory-manager=ptmalloc2.
Only tested on Linux, not even compiled elsewhere. Do not use
on OS X, or you will never see your process again.
* Added AM_CONDITIONAL for threads test to support ptmalloc2's build
system

I'll send out a general note about this in the morning, but for now I'll just notify people through this note that the new simplified "put" commands have been debugged and work just fine. I'll add documentation to the gpr.h file later - only think to really be aware of is that the tokens array must be NULL terminated. Other than that, things work pretty much as you'd expect.

- Update svn:ignore's to match new exectuable names
- Consolidate the unit test Makefile.am flags into a testing
Makefile.options
- Remove a bunch of SUBDIRS from test/mca/Makefile so that they don't
run by default, but can be invoked manually (they're still in
DIST_SUBDIRS)

unit tests without screwing up the nightly builds.
These changes fix the problem of not including the test/mca/gpr
directory in the nightly tarball, prevent the tests from being
compiled, but leave the door open for manual compilation when the time
comes to start the work to re-enable them (e.g., uncomment a few
lines in gpr/Makefile.am).
This commit was SVN r6175.
Also included is a fix to the attribute problem for singletons.
Short explanation:
The prior system placed triggers and subscriptions on the registry for each process - approximately eight/process. Each of these had to be checked every time there was a registry operation such as a "put" or "increment-value". For large numbers of processes, this repetitive checking consumed some significant time.
The new system allows processes to "attach" to existing triggers and subscriptions, without creating a new one. Thus, there are now only eight triggers and five subscriptions on a job - *regardless of how many processes are being run*. This means that the registry now takes the same amount of time (which is pretty darn short) to process an operation regardless of how many processes are in a job.
I'll provide some startup times from scalability tests shortly - need to complete the commit so I can move the system to an appropriate cluster.

the RDS selection logic, which is, unfortunately, not yet well
supported by the testing infrastructure (it causes false failures in
the nightly build).
This commit was SVN r6073.
For anyone interested, the problem stemmed from two things:
1. a bug in the ompi_bitmap utility (which I copied to orte_bitmap to avoid unintentionally disturbing something else) that causes the bitmap NOT to expand unless the caller asks for a bit that is more than one byte outside the current array size. The unit test didn't pick it up because it doesn't check that close to the boundary.
2. a "feature" in the ompi_bitmap utility that only expands the array if you try to SET a bit outside the current boundary, but NOT if you try to CLEAR a bit outside the array limit. This appears intentional as the unit test checks for this behavior, but I hadn't been expecting the asymmetry.
The orte_bitmap utility now appropriately expands in both circumstances. I also added a function to expand the array so it "covers" a bit location without setting or clearing it. The function allows you to ensure the array is big enough to handle the specified bit, but leave the bit alone if it already is there (the other functions would set/clear it if it was).
I've tested it with up to 100 processes without problem.

call the memory pool to do special memory allocations, and extended
the mpool so that it will do the allocations and keep tack of them in
a tree. Currently, if you pass MPI_INFO_NULL to MPI_Alloc_mem, we will
try to allocate the memory and register it with as many mpools as
possible. Alternatively, one can pass an info object with the names of
the mpools as keys, and from these we decide which mpools to register
the new memory with.
- fixed some comments in the allocator and fixed a minor bug
- extended the red black tree test and made a minor correction

Need to do some refining of the component, but it meets basic requirements right now. Nobody else should notice any change - system basically ignores it unless you tell it to do something.
This commit was SVN r5723.
- Change all uses of *printf'ing a size_t to use an explicit cast to
(unsigned long) and the %lu escape
- change ORTE_GPR_REPLICA_MAX_SIZE to INT_MAX until bug 1345 is fixed
(i.e., until we allow size_t in MCA params)
- ns_base_local_fns.c:orte_ns_base_get_proc_name_string(): changed
from %0X -> %lu
- ORTE_NAME_ARGS added explicit (unsigned long) casts, and changed all
usages of ORTE_NAME_ARGS to use %lu's

1. Added pid_t to the dps
2. Processes now "register" their local pid and update their location (i.e., nodename) on the registry during mpi_init
3. Added a new error code for values that exceed maximum for their data type (useful when transitioning a value from one variable to another of different size)
4. Fixed a few places where size_t was being incorrectly handled
5. Updated dps_test to cover pid_t types
This should now provide support for TotalView connection - which David is pursuing.

HEADS UP: string versions of names are now presented in DECIMAL format - not HEX as they previously were. If you used the name services functions (as you were supposed to do) to access these names, you will not have any problems. If you did it yourself, then you need to fix it - my suggestion would be that you fix your code by using the name service functions to avoid future problems.

1. *correctly* fix the printing of size_t variables. Need to do this through a #define, not just typecast things. Thanks to Jeff/Brian for suggesting a cleaner way to do it (as opposed to just doing the #define at the print location). Note that not ALL of the prints have been "fixed" yet - will continue to identify them.
2. Add int64 and size_t to the pack/unpack unit tests.
3. Fix a bug in the int64 pack/unpack system.
