Cleanup a typo, and remove no longer needed MCA params for hetero nodes and hetero apps. Hetero nodes will always be automatically detected. We don't support a mix of 32 and 64 bit apps
Modify the orte_node_t to use orte_topology_t instead of hwloc_topology_t, updating all the places that use it. Ensure that we properly update topology when we see a different one on a compute node.

Due to the conversion from ssize_t to int we were losing bytes, and
ended up writing outside the receiver buffer. Similarly on the send,
due to the conversion to a lesser type, we could missinterpret the
end of the fragment.
Do not call component's init function until the component has been
selected.
Use mca_base_select() instead of the custom component selection code.

* ess/hnp: add support for forwarding additional signals
This commit adds support to the hnp ess module to forward additional
signals beyond the default SIGUSR1, SIGUSR2, SIGSTP, and SIGCONT.

* Generalize this a bit to allow a broader range of signals to be forwarded. Turns out that SIGURG is now a "standard" signal, though the value differs across systems. So setup to forward it (and some friends) if they are defined. Allow users to provide the signal name (instead of the integer value) as the value of even the more common signals does vary across systems. Don't limit the number that can be supported.

* ess/hnp: fix some bugs in the signal forwarding code
This commit fixes two bugs:
- signals_set needs to be set even if no signals are being
forwarded. If it is not set we will SEGV in libevent if
ess_hnp_forward_signals == none.
- SIGTERM and SIGHUP are handled with a different type of handler. Do
not allow the user to specify these to be forwarded.

state machine tells it to do so. This plugs leaked file descriptors as
we were losing track prior to destructing the resources.

The linux timer code was multiplying the result of the x86 time stamp
counter by 1000000 before dividing by the cpu frequency. This can
cause us to overflow 64 bits if the time stamp counter grows larger
than ~ 1.8e13 (about 8400 seconds after boot). To fix the issue the
units of opal_timer_linux_freq have been changed to MHz.

the hwloc topology might not contain a NUMA object with hwloc < v2
if the node is not NUMA, so force the NUMA object count to one
in order to correctly allocate mca_btl_sm_component.sm_mpools.

This commit fixes a deadlock that can occur when the libc version
holds a lock when calling munmap. In this case we could end up calling
free() from vma_tree_delete which would in turn try to obtain the lock
in libc. To avoid the issue put any deleted vma's in a new list on the
vma module and release them on the next call to vma_tree_insert. This
should be safe as this function is not called from the memory hooks.
