* Remove the 'opal_mca_base_param_use_amca_sets' global variable
* Harness the fact that you can (read should) call the cmd_line functions
before initializing opal_init_util(). This pushes the MCA/GMCA/AMCA
command line options into the environment before OPAL inits and starts
to use these values. By putting the cmd_line parse before opal_init_util
in orterun and orted we only parse the *MCA parameter files once, and
correctly (alleviating the need to 'recache' the files on init.)
* Small bits of cleanup.

Per suggestion, if we don't find a valid shell via getpwuid(), also
check the $SHELL environment variable. Also perform a few minor
cleanups along the way.

The following Trac tickets were found above:
Ticket 1060 --> https://svn.open-mpi.org/trac/ompi/ticket/1060
(and, due to lack of in code documentation, in r14661).
The {{{opal_mca_base_param_use_amca_sets}}} flag tells the orted that it should
not look at the parameter files just yet since it may have an AMCA parameter
file to look at first. So we need to set this to {{{false}}} before initializing
the MCA paras, then quickly turn around and re-init them when we have the full
information.

The SnapC Full local Coordinator used this argument to attach to the job the
daemon would be launching. So once this option was removed C/R support broke.
This commit has the local coordinator attach to the job just before it is
launched by the ODLS module. This is a much cleaner solution, and will
eventually allow the SnapC modules to attach to multiple jobs launched
on a single machine.
This commit fixes the C/R regression introduced in r15007.

the multiple threads accessing the OOB/registry asynchronously via the
callbacks. The quickest solution (but definitively not the cleanest) is
to serialize these callbacks in such a way that at any given time
only one thread can execute a callbacks.

through the win dll using multiple threads, we have to insure that
the oob callbacks happens only in a synchronous way or really bad
things happens with the current design (blocking messages from a receive
callback).
This commit was SVN r15069.
The warning was indicative of overly-complex code anyway. So I
removed the "first" bool and simply use a sentinel value in seq_min to
indicate that nothing has changed. Note that this is "correct enough"
for the moment -- more fixes will come in this area with tickets #1049
and/or #1051.

single threaded builds. In its default configuration, all this does
is ensure that there's at least a good chance of threads building
based on non-threaded development (since the variable names will be
checked). There is also code to make sure that a "mutex" is never
"double locked" when using the conditional macro mutex operations.
This is off by default because there are a number of places in both
ORTE and OMPI where this alarm spews mega bytes of errors on a
simple test. So we have some work to do on our path towards
thread support.
Also removed the macro versions of the non-conditional thread locks,
as the only places they were used, the author of the code intended
to use the conditional thread locks. So now you have upper-case
macros for conditional thread locks and lowercase functions for
non-conditional locks. Simple, right? :).

1. generalize orte_rml.xcast to become a general broadcast-like messaging system. Messages can now be sent to any tag on the daemons or processes. Note that any message sent via xcast will be delivered to ALL processes in the specified job - you don't get to pick and choose. At a later date, we will introduce an augmented capability that will use the daemons as relays, but will allow you to send to a specified array of process names.
2. extended orte_rml.xcast so it supports more scalable message routing methodologies. At the moment, we support three: (a) direct, which sends the message directly to all recipients; (b) linear, which sends the message to the local daemon on each node, which then relays it to its own local procs; and (b) binomial, which sends the message via a binomial algo across all the daemons, each of which then relays to its own local procs. The crossover points between the algos are adjustable via MCA param, or you can simply demand that a specific algo be used.
3. orteds no longer exhibit two types of behavior: bootproxy or VM. Orteds now always behave like they are part of a virtual machine - they simply launch a job if mpirun tells them to do so. This is another step towards creating an "orteboot" functionality, but also provided a clean system for supporting message relaying.
Note one major impact of this commit: multiple daemons on a node cannot be supported any longer! Only a single daemon/node is now allowed.
This commit is known to break support for the following environments: POE, Xgrid, Xcpu, Windows. It has been tested on rsh, SLURM, and Bproc. Modifications for TM support have been made but could not be verified due to machine problems at LANL. Modifications for SGE have been made but could not be verified. The developers for the non-verified environments will be separately notified along with suggestions on how to fix the problems.

structures in the system. Instead of using memcmp, use the ns function.
This won't cause a problem as long as all three elements of the name are
ints, but if they have different sizes, alignment and padding rules
can cause memcmp() to compare padding space, which rarely holds a sane
value.
