Added a reader/writer locking mechanism to allow multiple
concurrent namespace walks (readers), but a dynamic table unload
will have exclusive access to the namespace. This fixes a problem
where a table unload could delete the portion of the namespace that
is currently being examined by a walk. Adds a new file, utlock.c
that implements the reader/writer lock mechanism. ACPICA BZ 749.

Added acpi_hw_write_pm1_control. This function writes both of the PM1
control registers (A/B). These registers are different than than
the PM1 A/B status and enable registers in that different values
can be written to the A/B registers. Most notably, the SLP_TYP
bits can be different, as per the values returned from the _Sx
predefined methods.

This type is the same as TYPE_A. Removed this and all related
instances. Renamed SLEEP_TYPE_A to simply SLEEP_TYPE.
