With this commit we finally have a way to read and manipulate basic resctrl
settings. Locking is done only on exposed functions that read/write from/to
resctrlfs. Not in functions that are exposed in virresctrlpriv.h as those are
only supposed to be used from tests.

This way later patches can add another structures with virResctrl
prefix without the meaning being even more confusing than it needs to
be.

values differ in meaning, but are all successful.

It doesn't access anything from conf/ and ti will be needed to use
from other util/ places. This split makes the separation clearer.
