[ACPI] ACPICA 20051216

Implemented optional support to allow unresolved names
within ASL Package objects. A null object is inserted in
the package when a named reference cannot be located in
the current namespace. Enabled via the interpreter slack
flag which Linux has enabled by default (acpi=strict
to disable slack).  This should eliminate AE_NOT_FOUND
exceptions seen on machines that contain such code.

Implemented an optimization to the initialization
sequence that can improve boot time. During ACPI device
initialization, the _STA method is now run if and only
if the _INI method exists. The _STA method is used to
determine if the device is present; An _INI can only be
run if _STA returns present, but it is a waste of time to
run the _STA method if the _INI does not exist. (Prototype
and assistance from Dong Wei)

Implemented use of the C99 uintptr_t for the pointer
casting macros if it is available in the current
compiler. Otherwise, the default (void *) cast is used
as before.

Fixed some possible memory leaks found within the
execution path of the Break, Continue, If, and CreateField
operators. (Valery Podrezov)

Fixed a problem introduced in the 20051202 release where
an exception is generated during method execution if a
control method attempts to declare another method.
