[ACPI] ACPICA 20050125 from Bob Moore

Fixed a recently introduced problem with the Global
Lock where the underlying semaphore was not created.
This problem was introduced in version 20050114, and
caused an AE_AML_NO_OPERAND exception during an Acquire()
operation on _GL.

The local object cache is now optional, and is disabled
by default.  #define ACPI_ENABLE_OBJECT_CACHE to enable
the local cache.

Fixed an issue in the internal function
acpi_ut_evaluate_object() concerning the optional "implicit
return" support where an error was returned if no return
object was expected, but one was implicitly returned. AE_OK
is now returned in this case and the implicitly returned
object is deleted.  acpi_ut_evaluate_object() is only
occasionally used, and only to execute reserved methods
such as _STA and _INI where the return type is known
up front.

Fixed a few issues with the internal convert-to-integer
code. It now returns an error if an attempt is made to
convert a null string, a string of only blanks/tabs, or a
zero-length buffer. This affects both implicit conversion
and explicit conversion via the ToInteger() operator.

The internal debug code in acpi_ut_acquire_mutex()
has been commented out. It is not needed for normal
operation and should increase the performance of the entire
subsystem. The code remains in case it is needed for debug
purposes again.
