the ptmalloc2 memory hooks component triggers callbacks for memory
allocation / deallocation. If enabled (the default) it is only when
memory is actually obtained from or released to the OS (so little
malloc calls only trigger callbacks if sbrk is called). If disabled,
callbacks are triggered every time malloc/free/etc. is called
* It turns out that syscall and mmap aren't good friends due to the return
type of mmap and some old legacy issues with syscall functions that
take more than 5 parameters. For now, default to either loading
the symbol from glibc using dlsym or using the __m{un,}map functions.
Thanks to George for finding this.

both mmap and munmap), adjusting the configure script so that the
component will only be activated on systems that use ptmalloc2 in the
first place -- ie, Linux
* Remove the malloc_hooks component - it became an unworkable solution
once threads and such were considered.
* Remove malloc_interpose component - it never worked quite right and
was not going to be able to intercept malloc, so it wasn't going to
be useful for OMPI's purposes.
* Update tests a little bit to match recent memory hooks api
issues - still needs a bit of work.

component/base Makefile.am files, reducing the time configure spends
stamping out Makefiles at the end
* Install base_impl.h file when devel-headers are being installed
This commit was SVN r8200.
When compiling C++ code that includes something that looks for the C++
header file "memory" (stupid C++ headers not having .h extensions), it
goes through the header file search path, which includes $(topsrcdir)/opal,
so it finds the directory $(topsrcdir)/opal/memory/ and tries to load
that as the memory header file and all goes downhill.

* allocator, rcache, and mpool were putting things in the wrong place
* timer wasn't installing the inline implementations at all

originally suggested by Ralf Wildenhues, to try to speed autogen, configure,
and make (and possibly even make install). Use automake's include directive
to drastically reduce the number of Makefile files (although the number of
Makefile.am files is the same - most are just included in a top-level
Makefile.am). Also use an Automake SUBDIRs feature to eliminate the
dynamic-mca tree, which was no longer really needed. This makes adding
a framework easier (since you don't have to remember the dynamic-mca
tree) and makes building faster (as make doesn't have to recurse through
the dynamic-mca tree)

OMPI_CHECK_PACKAGE macro instead of doing everything ourself.
The old code was causing problems - it wouldn't add anything to
WRAPPER_EXTRA_{LDFLAGS, LIBS} if libnuma was installed in /usr,
so it didn't work so well.
This should go to the 1.0 branch

set it to empty if it isn't. __malloc_attribute__ is set in sys/cdef.h, and
some versions set it unconditionally. If sys/cdef.h is included after malloc.h,
some compilers will complain loudly. So include malloc.h at the end so that
sys/cdef.h is already included if it's going to be.

in-place already (turns out that I was wrong in thinking that it
didn't work for static components), but the logic for excluding
components was not there. This commit does a few things:
- Adds "exclude" logic, so that you can do:
mpirun --mca btl ^mvapi,openib ...
(note the "^" character -- I tried "!" but then you have to escape
it in the shell, and that was icky) which will exclude both the
mvapi and openib btl components (excluding one component means that
you are excluding all components in the list; it doesn't make sense
to include some and exclude others -- you're entire entirely
including or entirely excluding)
- Simplifies the "include" logic, so the same old stuff like this
still works:
mpirun --mca btl tcp,self ...
will only use the tcp and self btl components.
- Added more verbosity statements to make this selection process
clear.

really can't. Test for munmap, since it's the most likely to cause problems,
since it's always an interposed symbol.
The condition that usually causes problems is if libmpi was brought in as
the result of a library dependency, rather than as a -l on the link line.
The linker in this case will find malloc/free/munmap/etc. in libc, rather
than in libmpi.

Makefile.options
- Sample in each of the three projects of how to link againt the
relevant libraries so that when components are loaded into a parent
process' space, we don't rely on the libopal/liborte/libmpi symbols
being in the parent's public symbol namespace -- instead,
dynamically link to the relevant libraries, allowing the dynamic
linker to pull those libraries in at run-time, if needed

AM_INIT_AUTOMAKE, instead of the deprecated version.
* Work around dumbness in modern AC_INIT that requires the version
number to be set at autoconf time (instead of at configure time, as
it was before). Set the version number, minus the subversion r number,
at autoconf time. Override the internal variables to include the r
number (if needed) at configure time. Basically, the right thing
should always happen. The only place it might not is the version
reported as part of configure --help will not have an r number.
* Since AM_INIT_AUTOMAKE taks a list of options, no need to specify
them in all the Makefile.am files.
* Addes support for subdir-objects, meaning that object files are put
in the directory containing source files, even if the Makefile.am is
in another directory. This should start making it feasible to
reduce the number of Makefile.am files we have in the tree, which
will greatly reduce the time to run autogen and configure.

it.
