Allow perfmon bundles to support more than one bundle type, either node
or thread. Only used for topdown bundle for the moment.

Added memory bandwidth boundedness bundle, closely related to cache-hierarchy.
This bundle works on ICX only, due to an ICX specific counter.

Adding support for Linux papi TMAM on Intel Snowridge. Adds the ability to
indicate that a bundle should be thread or node bundle type based on available
cpu features (rdpmc support).

Original set, start, stop, reset, show etc interface was somewhat cumbersome, we
can improve slightly by combining set and start.

Add perfmon plugin support to output raw counter and timestamps, both
are useful for debug.

Callbacks for monitoring and performance measurement:
- Add new callback list type, with context
- Add callbacks for API, CLI, and barrier sync
- Modify node dispatch callback to pass plugin-specific context
- Modify perfmon plugin to keep PMC samples local to the plugin
- Include process nodes in dispatch callback
- Pass dispatch function return value to callback

Add missing pre-input node runtime fork and refork code.
unix-epoll-input runs on all threads; each instance needs its own
runtime stats.

As a FUD reduction measure, this patch implements 2-way parallel
counter collection. Synthetic stat component counter pairs run at the
same time. Running two counters (of any kind) at the same time
naturally reduces the aggregate time required by an approximate
factor-of-2, depending on whether an even or odd number of stats have
been requested.
I don't completely buy the argument that computing synthetic stats
such as instructions-per-clock will be inaccurate if component counter
values are collected sequentially. Given uniform traffic pattern, it
must make no difference.
As the collection interval increases, the difference between serial
and parallel component counter collection will approach zero, see also
the Central Limit theorem.
