* Add malloc_interpose memory manager intercept functions that should work on all glibc systems (tested with x86 and x86_64 with a couple of C++ compilers). While not as ideal as the malloc_hooks method, it does have the advantage of working with threads. * Modified malloc_hooks component to properly follow prefix rule. No functionality changes * Make the memory framework only chose one component, and modify all components to set priority to 20, except malloc-interpose, which is at 10. This means that on Linux, malloc_hooks will be used unless threads are enabled, since I think malloc_hooks is a better design choice when we can use it This commit was SVN r6949.

Add ummunotify support to Open MPI. See http://marc.info/?l=linux-mm-commits&m=127352503417787&w=2 for more details. * 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). This commit was SVN r23113.

WARNING: Work on the temp branch being merged here encountered problems with bugs in subversion. Considerable effort has gone into validating the branch. However, not all conditions can be checked, so users are cautioned that it may be advisable to not update from the trunk for a few days to allow MTT to identify platform-specific issues. This merges the branch containing the revamped build system based around converting autogen from a bash script to a Perl program. Jeff has provided emails explaining the features contained in the change. Please note that configure requirements on components HAVE CHANGED. For example. a configure.params file is no longer required in each component directory. See Jeff's emails for an explanation. This commit was SVN r23764.

Fixes trac:2844: ensure to take the value of --with(out)-memory-manager into account when configuring the components of the faramework. If --without-memory-manager was given, then we really don't want any memory managers to be used. This commit was SVN r25807.
