Subject: ACPICA: Delete recursive feature of ACPI Global Lock

Completed a new design and implementation for
the ACPI Global Lock support. On the OS side, the global
lock is now treated as a standard AML mutex. Previously,
multiple OS threads could acquire the global lock
simultaneously, but this could cause the BIOS to be starved
by the lock in cases such as the Embedded Controller driver,
where there is a tight coupling between the OS and the BIOS.

Subject: ACPICA: Implement simplified Table Manager

The Table Manager component has been completely
redesigned and reimplemented. The new design is much
simpler, and reduces the overall code and data size of
the kernel-resident ACPICA by approximately 5%. Also,
it is now possible to obtain the ACPI tables very early
during kernel initialization, even before dynamic memory
management is initialized.

Subject: ACPICA: Re-implement interpreters' "serialized mode"

Enhanced the implementation of the interpreters'
serialized mode (boot with "acpi_serialize" to set
acpi_glb_all_methods_serialized flag.)
When this mode is specified, instead of creating a serialization
semaphore per control method, the interpreter lock is
simply no longer released before a blocking operation
during control method execution. This effectively makes
the AML Interpreter single-threaded. The overhead of a
semaphore per-method is eliminated.

Subject: ACPICA: Fix for Global Lock semaphore.

Fixed a problem with the Global Lock where the lock could appear to be obtained before it is actually obtained, semaphore created with one unit.

Subject: ACPICA: Fix race condition with AcpiWalkNamespace.

Fixed a problem with a possible race condition between threads executing
AcpiWalkNamespace and the AML interpreter. This condition was removed by
modifying AcpiWalkNamespace to (by default) ignore all temporary
namespace entries created during any concurrent control method execution
