libroot: Remove _SC_NPROCESSORS_MAX and _SC_CPUID_MAX
...
_SC_NPROCESSORS_MAX and _SC_CPUID_MAX appear to be supported only by
Solaris. There isn't much point in exposing such values to the userland
anyway.

scheduler_common.h is now meant for types, variables and functions used
by both core scheduler code and implementations of scheduler modes.
Functions like switch_thread() and update_thread_times() do not belong
there anymore.

preferences: Remove CPUFrequency
...
We can't reliably set contemporary processors to an arbitrary frequency.
There are dependencies between cores and thechnologies like Turbo Boost
which may make actual frequency significantly different than the requested.
Moreover, it is the scheduler job to decide how much CPU performance is
needed and user shouldn't interfere with that.

drivers: Remove Intel Enhanced SpeedStep driver
...
In current state this driver is useless anyway. It's not MP safe.
The P-state values stored in hardcoded tables are only for processors
on which we can't use SpeedStep, because of lack of invariant TSC.
Proper driver should get P-states from ACPI, ensure that the CPU offers
invariant TSC and obviouslt be MP safe.
