ACPI: ACPICA 20060310 

Tagged all external interfaces to the subsystem with the
new ACPI_EXPORT_SYMBOL macro. This macro can be defined
as necessary to assist kernel integration. For Linux,
the macro resolves to the EXPORT_SYMBOL macro. The default
definition is NULL.

Added the ACPI_THREAD_ID type for the return value from
acpi_os_get_thread_id(). This allows the host to define this
as necessary to simplify kernel integration. The default
definition is ACPI_NATIVE_UINT.

Valery Podrezov fixed two interpreter problems related
to error processing, the deletion of objects, and placing
invalid pointers onto the internal operator result stack.

Increased the reference count threshold where a warning is
emitted for large reference counts in order to eliminate
unnecessary warnings on systems with large namespaces
(especially 64-bit.) Increased the value from 0x400
to 0x800.

Due to universal disagreement as to the meaning of the
'c' in the calloc() function, the ACPI_MEM_CALLOCATE
macro has been renamed to ACPI_ALLOCATE_ZEROED so that the
purpose of the interface is 'clear'. ACPI_MEM_ALLOCATE and
ACPI_MEM_FREE are renamed to ACPI_ALLOCATE and ACPI_FREE.
