Modify logic used to get socket/core/thread information from
a common function in slurmd. This common function supports
board count and some additional processors that the task/cgroup

There is more possible this was just low hanging fruit.

This is needed to figure out the unused wall clock time on them.

Bug 4246

No other options use underscores, so make these consistent with
the rest. Both old and new syntax is supported for now.

the testsuite to match.

Fix a few related documentation errors while here.

Turns out what was there before was completely incorrect.
