This commit does a bunch of things:
* Address all remaining code review items from CMR #2023:
* Defer mmap setup to be lazy; only set it up the first time we
invoke a collective. In this way, we don't penalize apps that
make lots of communicators but don't invoke collectives on them
(per #2027).
* Remove the extra assignments of mca_coll_sm_one (fixing a
convertor count setup that was the real problem).
* Remove another extra/unnecessary assignment.
* Increase libevent polling frequency when using the RML to
bootstrap mmap'ed memory.
* Fix a minor procs-related memory leak in btl_sm.
* Commit a datatype fix that George and I discovered along the way to
fixing the coll sm.
* Improve error messages when mmap fails, potentially trying to
de-alloc any allocated memory when that happens.
* Fix a previously-unnoticed confusion between extent and true_extent
in coll sm reduce.

NOTE: the IPv6 support is currently marginally working and has problems when IPv6 headers are present but the interfaces are not configured to use that protocol, per several reports from users. It is unclear that anyone is willing/able to support this capability. Should that situation change, this change can be reconsidered.

(yay cisco webex!). Make sure we only go up to OPAL max datatype, not
OMPI max datatype.

- add an orte ftb notifier help file for more verbose error messages
- check if we can connect to the FTB during component->query and close
the component, if we cannot.
- make the ftb component interface methods static.
- add mca parameters to set override the default subscription style and
priority.

1. ensure that orte_rmaps_base_schedule_policy does not override cmd line settings
2. when you try to bind to more cores than we have, generate a not-enough-processors error message
3. allow npersocket -bind-to-core combination - because, yes, somebody actually wants to do it.

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.
