* add "register" function to mca_base_component_t
* converted coll:basic and paffinity:linux and paffinity:solaris to
use this function
* we'll convert the rest over time (I'll file a ticket once all
this is committed)
* add 32 bytes of "reserved" space to the end of mca_base_component_t
and mca_base_component_data_2_0_0_t to make future upgrades
[slightly] easier
* new mca_base_component_t size: 196 bytes
* new mca_base_component_data_2_0_0_t size: 36 bytes
* MCA base version bumped to v2.0
* '''We now refuse to load components that are not MCA v2.0.x'''
* all MCA frameworks versions bumped to v2.0
* be a little more explicit about version numbers in the MCA base
* add big comment in mca.h about versioning philosophy

ibv_dereg_mr() for instance) from ptmalloc callback. Call to free() from the
callback causes deadlock. Notice what should be unregistered inside the callback
and do actual cleanup at the next call to mpool->register().

(sometimes after the merge with the ORTE branch), the opal_pointer_array
will became the only pointer_array implementation (the orte_pointer_array
will be removed).
This commit was SVN r17007.
This merge adds Checkpoint/Restart support to Open MPI. The initial
frameworks and components support a LAM/MPI-like implementation.
This commit follows the risk assessment presented to the Open MPI core
development group on Feb. 22, 2007.
This commit closes trac:158

udapl/openib/vapi/gm mpools a deprecated. rdma mpool has parameter that allows
to limit its size mpool_rdma_rcache_size_limit (default is 0 - unlimited).

- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

searching the tree. Modified the memory callback to search the tree at each
page boundary for registrations. This is necessary as an application may
malloc memory and send out of any portion of that memory, even discontiguous
regions.

be used in MPI_Alloc_mem operations. Note that we found an interesting bug in
which if memory was allocated by the sm mpool (via mmap) and then registered
via the mvapi mpool, the registration would fail on certain systems.
Added mca param mpool_base_use_mem_hooks, set to 1 to enable the memory hooks
so that memory is deregistered if the user frees it behind our back. This is
only useful if the mca param mpi_leave_pinned is also set to 1. Otherwise all
registrations are deregistered within the MPI library or via
MPI_Free_buf. After testing we should probably set both mpi_leave_pinned and
mpool_base_use_mem_hooks to default to 1.

corrected free and realloc in mpool. Added alloc_base to
mca_mpool_base_registration_t to be used as the actual alloc'd base address,
which may be different from the reported base address due to page allignment.

- move mpool and allocator frameworks back to ompi (from opal)
- specialize the ompi_free_list class to use an mpool instance
- un-specialize opal_free_list to *not* use mpool; just use malloc/free
