I have no machine which allows me to do external binding, so I will have to ask others to test the new logic. However, I did verify that these changes don't break the existing logic when no external bindings were present.

lower the default priority of PML/cm to allow _defined_ behaviour
for systems, where both MTLs and BTLs are available (Portals and MX).
Keep the previous behaviour of favoring in case of PSM.
Still, the user may select --mca pml cm for apps where applicable.

now are able to use the dynamic rules. Moreover, these rules are loaded only once,
and stored at the component level. All communicators are able to use these rules
(not only MPI_COMM_WORLD as until now).
A lot of minor corrections, memory management issues and reduction in the amount
of memory used by the tuned collectives.

Add a capability to parse the rankfile to extract node information in place of requiring both hostfile and rankfile for non-RM managed environments. The rankfile is -only- parsed for this IF the hostfile and -host options are not given. Otherwise, those are used to establish allocation info as we did before this commit.

BTL/sm. This static variable needlessly ends up in the so.-file.
init_maffinity is called once from sm_btl_first_time_init.
Checked with lennyve, static here is not necessary.

- 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.

support for _Complex is disabled until we figure out the correct
black magic. So instead of using this nice C99 feature, we use the
a strcture with a double type, the same approach that worked pretty
well for the last couple of years.
Switching from one mode to the other is done using the
OPAL_USE_[FLOAT|DOUBLE|LONG_DOUBLE]__COMPLEX macros defined in
opal_datatype_internal.h at line 442.

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.
