if posix_memalign() fails, it's not always going to be due to
out-of-memory -- just return ERR_IN_ERRNO.

This commit looks larger than it really is since it includes a fair amount of code cleanup.
The SIGSTOP/SIGCONT+checkpointing work uses some of the functionality in r20391. Basic use case below (note that the checkpoint generated is useable as usual if the stopped application is terminated).

Other items in this commit are mostly cleanup that has been sitting off-trunk for too long:
* Add a new {{{opal_crs_base_ckpt_options_t}}} type that encapsulates the various options that could be passed to the CRS. Currently only TERM and STOP, but this makes adding others ''much'' easier.
* Eliminate ORTE_SNAPC_CKPT_STATE_PENDING_TERM, since it served a redundant purpose with the new options type.
* Lay some basic ground work for some future features.

masks between the mask argument and a local PLPA mask. There were three
problems:
1) The "get" function computed the number of bits as sizeof(mask),
which is the size of the pointer to the mask rather than the mask
itself. So, only 4 bits were copied with m32 and 8 bits with m64.
There are actually 1024 bits.
2) The "get" and "set" functions both copied a number of bits computed
from the sizeof() mask, but sizeof() reports the number of bytes.
We have to multiply by 8 to get the number of bits.
3) These two functions check to make sure tha the mask argument is not
bigger than the PLPA mask. But, the set function copies a number
of bits in the PLPA mask, which is conceivably greater than the
number of bits in the mask argument. So, accesses to the mask
argument may overrun that argument.
Problems 1 and 2 meant that one would encounter errors when the number of
cores exceeded 4 (with -m32) or 8 (with -m64). Problem 3 probably caused
no errors.
This commit was SVN r21993.
The new options work by adding an ":if-avail" qualifier to the "bind-to-socket" and "bind-to-core" MCA params. If the system does not support this capability, the job will launch anyway. Without the qualifier, the job will abort with an error message indicating that the required functionality is not supported on this system.
This commit was SVN r21975.
Due to a typo (probably cut/paste error) the CFLAGS/CPPFLAGS/LDFLAGS/LIBS arguments were not propogated to the BLCR component.
This changes a few {{{crs_blcr_check_}}} to {{{crs_blcr_save}}}, which they should have been all along.
This needs to be applied to v1.3 as well :/

- add a cmake module for searching libltdl libraries and headers
- a configure option to enable DSO build, default OFF.
- update a few source files for including correct header
and loading correct mca libraries path/suffix.
This commit was SVN r21804.
Adds several new mpirun options:
* -bysocket - assign ranks on a node by socket. Effectively load balances the procs assigned to a node across the available sockets. Note that ranks can still be bound to a specific core within the socket, or to the entire socket - the mapping is independent of the binding.
* -bind-to-socket - bind each rank to all the cores on the socket to which they are assigned.
* -bind-to-core - currently the default behavior (maintained from prior default)
* -npersocket N - launch N procs for every socket on a node. Note that this implies we know how many sockets are on a node. Mpirun will determine its local values. These can be overridden by provided values, either via MCA param or in a hostfile
Similar features/options are provided at the board level for multi-board nodes.

Refs trac:1987
The patch for v1.3 attached to Ticket #1987 already includes this change.
I did not have a chance to commit this last night, so sorry for the delay.
This commit was SVN r21777.
The following Trac tickets were found above:
Ticket 1987 --> https://svn.open-mpi.org/trac/ompi/ticket/1987
* Check for {{{dlfcn.h}}} in the self component's configure.m4 (also clean up the .m4 a bit.
* Adjust the priority of the BLCR component so that the self component has a higher priority (if the application went to the trouble of writing the routines, why not use them.) The 'self' component checks for the appropriate functions during query, so it know if it -can- be used during component selection.
* Adjust some copyrights that I missed before
* Fix a warning when casing the result of dlsym() into a function pointer. There is a bit of pointer magic to make this happen (thanks to the following website, and RedHat EL 4 man pages for illustrating it:
http://www.opengroup.org/onlinepubs/009695399/functions/dlsym.html
Passing to Jeff for a final review of the patch before moving to v1.3.
This commit was SVN r21768.
The following SVN revision numbers were found above:
r21766 --> open-mpi/ompi@91e52d062b
Due to the visibility patch to libltdl in r21731, this module can no longer access or use the libltdl interfaces directly. Instead just use the dlopen/dlsym/dlclose functions directly. This is a portability implication here, but for the moment it does not seem to bite us.
Also in this patch, cleanup some of the 'self' specific code paths.
* opal-restart need not special case the 'self' component since it can now interact with it as if it were a normal component.
* Cleanup the initialization of the cmd line arguments in opal-restart.
* Make sure to mark opal-restart as a 'tool', but do so by setting the global variable directly instead of setting the environment variable, which could be inherited by the application.
* Most of the functions in the 'self' component should not be used by a command line tool (exception being 'restart'), so make sure that if we accidently call them then errors are returned.
* Increase the priority of the 'none' component to be above that of 'self' when being selected in a command line tool. This allows for both mpirun and opal-restart to work correctly with the 'self' module.

* Installation directories will be inferred from the actual location
of the shared library that contains the component.
* OPAL_PREFIX and other environment variables allow users to override
the inferred directories. They should no longer be necessary in
most cases, though.
* Any directories that cannot be inferred will fall back to whatever
is provided by the config installdirs component.

Revamp the affinity detection/set procedure in mpi_init to correctly detect when we have already been bound to processors, given the revised understanding of paffinity_get. Add a new paffinity macro to make checking for already bound a little nicer.
This commit was SVN r21402.
Libltdl erroneously returns an error string of "file not found" for
lots of reasons, even if the file really *is* there, but just failed
to dlopen() for some reason. So if lt_dlerror() returns "file not
found", do some simple hueristics and if we *do* find a file, print a
slightly better error message.
