Command-line util elab

We developed and installed on all our test machines a helper program called elab. We use this program to reliably set specific system parameters, like C-states, P-states, SMT. It is also used in some of the scripts part of this repository. The particular setting reference in any call should be easily derivable. For instance:

• elab ht on|off|enable|disable respectively enables and disables SMT, which is done by disabling all but the first thread sibling for every core
• elab frequency nominal sets the scaling governor to userspace and the used P-state to the nominal frequency of the processor
• elab frequency turbo is like elab frequency nominal, but also enables turbo frequencies
• elab cstate ... allows configuring the available C-states
