* Remove the ptmalloc memory component; replace it with a new "linux"
memory component.
* The linux memory component will conditionally compile in support
for ummunotify. At run-time, if it has ummunotify support and
finds run-time support for ummunotify (i.e., /dev/ummunotify), it
uses it. If not, it tries to use ptmalloc via the glibc memory
hooks.
* Add some more API functions to the memory framework to accomodate
the ummunotify model (i.e., poll to see if memory has "changed").
* Add appropriate calls in the rcache to the new memory APIs to see
if memory has changed, and to react accordingly.
* Add a few comments in the openib BTL to indicate why we don't need
to notify the OPAL memory framework about specific instances of
registered memory.
* Add dummy API calls in the solaris malloc component (since it
doesn't have polling/"did memory change" support).

MPI_WIN_SET_ERRHANDLER had their MPI handle parameters marked as INOUT
instead of IN, thereby disallowing passing pre-defined handles through
because they are constants (e.g., MPI_COMM_WORLD). This wasn't really
a problem for MPI_WIN_SET_ERRHANDLER since there are no predefined
windows, but it wasn't right.
This commit was SVN r23098.
- fixed bug in MPI-I/O tracing: tracking MPI file handles even if MPI_File_open isn't recorded
- fixed compiler warnings in the PAPI component
- incremented version number to 5.8.2

1. file activity - can monitor file size, access and modification times. If these fail to change over a specified number of sampling iterations (rate is an mca param), then the errmgr is notified.
2. memory usage - checks amount of memory used by a process. Limit and sampling rate can be set.
This support must be enabled by configuring --enable-sensors.
ompi_info and orte-info have been updated to include the new framework.
Also includes some initial steps toward restoring the recovery capability. Most notably, the ODLS API has been extended to include a "restart_proc" entry for restarting a local process, and organizes the various ERRMGR framework globals into a single struct as we do in the other ORTE frameworks. Fix an oversight in the ERRMGR framework where a pointer array was constructed, but not initialized.
Implementation continues.

ompi_ptr_t by translating into void*. Instead keep it as an ompi_ptr_t all
the way. Thanks to Timur Magomedov for helping to track down this issue and
test the patch.

--enable-mpi-ext configure switch in the top-level README file).
See Josh's excellent wiki page about OMPI extensions:
https://svn.open-mpi.org/trac/ompi/wiki/MPIExtensions
This extension exposes a new API to MPI applications:
{{{
int OMPI_Affinity_str(char ompi_bound[OMPI_AFFINITY_STRING_MAX],
char current_binding[OMPI_AFFINITY_STRING_MAX],
char exists[OMPI_AFFINITY_STRING_MAX]);
}}}
It returns 3 things. Each are a prettyprint string describing sets of
processors in terms of sockets and cores:
1. What Open MPI bound this process to. If Open MPI didn't bind this
process, the prettyprint string says so.
1. What this process is currently bound to. If the process is
unbound, the prettyprint string says so. This string is a
separate OUT parameter to detect the case where some other entity
bound the process (potentially after Open MPI bound it).
1. What processors are availabile in the system, mainly for reference.

- extendet support for BlueGene/P:
- building shared VT libraries
- tracing 3rd-party libraries (e.g. libc I/O)
- tracing multi-threaded applications
VT configure fixes:
- fixed detection on CTool for 3rd-party library tracing
VT fixes:
- reduced memory overhead by using the trace buffer for string/array elements of some records
- do not shutdown call-stack if max. number of buffer flushes reached, because the additional function leaves suggest a wrong application flow
- vtunify-mpi:
- fixed conversion of VTUnify_MPI_Aint arrays
- vtwrapper:
- if an OPARI modified object file (*.mod.o) cannot be renamed, abort only if the compiler wrapper runs in "only-compile" mode (-c)
OTF fixes:
- otfinfo:
- fixed and enhanced calculation of trace file size
- changed unit of timer resolution (s -> Hz)
- otfprofile:
- fixed progress
- kill '_' and '\' in process names to make LaTex happier

1. fix a bug that caused an infinite loop in configure when specifying want-ft but not want-ft-thread by removing a stale reference to the opal-progress-thread option
2. add want-ft=orcm so we can build the orcm errmgr component
3. cleanup the use of "ompi_want_ft_xxx" and replace it with "opal_want_ft_xxx" so that naming conventions are preserved

Adds memory barriers which are definitely needed on powerpc

Update ompi_info and orte-info to include the new framework.
Fix some selection logic and a typo'd variable name
Still remains ompi_ignored until we complete testing
This commit was SVN r22848.
Remove the --enable-progress-threads option as this is no longer functional, and hardcode OPAL_ENABLE_PROGRESS_THREADS to 0.
Replace the --enable-mpi-threads option with --enable-mpi-thread-multiple as this is clearer as to meaning. This option automatically turns "on" opal thread support if it wasn't already so specified. If the user specifies --disable-opal-multi-threads --enable-mpi-thread-multiple, we will error out with a message
Add a new --enable-opal-multi-threads option that turns "on" opal thread support without doing anything wrt mpi-thread-multiple

After talking to both Brian and George, the conensus was to just
remove the flag and the test function. Begone, evil spirits, BEGONE!

Dont use bash or bashism in shell scripts
We should use Posix' setpgid(0,0), which is equivalent to setpgrp().
This commit was SVN r22829.
Many of the OPAL_ENABLE_FT should be OPAL_ENABLE_FT_CR, so fix those.
The OPAL Layer INC should call opal_output on restart so that it can refresh the string it prints to reflect the current pid/hostname which may have changed.
This commit was SVN r22824.
- skip test for libdl on BlueGene? and CrayXT platforms (particularly on CrayXT this library can be linked but it isn't suitable)
- set cache variables for functions 'PMPI_Win_test', 'PMPI_Win_lock', 'PMPI_Win_unlock', and 'MPI_Register_datarep', if VT is configuring for Open MPI
- added test for pthread functions 'pthread_condattr_<set|get>pshared' and 'pthread_mutexattr_<set|get>pshared', because they are not available on some platforms
VT fixes:
- cut 'nm' collected symbol names at '??'
- vtunify:
- fixed unsafe usage of some strncpy's
- fixed potential segmentation fault in vtunify-mpi which might occur on 32bit platforms using MPICH2
OTF general:
- updated date in copyright header of each source file
OTF fixes:
- minor code cleanups (indentation, nicer error messages, more correct free's)
- otfaux:
- fix to place final statistics after the very last record instead of right before
- changed fatal error to a warning when a file is closed twice (or unexpectedly)
