Lv Zheng 0bac429552 ACPICA: Dispatcher: Move stack traversal code to dispatcher 
ACPICA commit c8275e243b58fd4adfc0362bd704af41ed14bc75

This patch moves parts of acpi_dm_dump_method_info() to the dispatcher
component.

This patch also makes the new function dependent on ACPI_DEBUG_OUTPUT
compile-stage definition so that it can be used by the trace facility.

acpi_dm_dump_method_info() traverses method stack when an exception is
encountered. Such traversal is needed to support method tracing for the
exceptions. When an exception is encountered, the end indications of the
aborted methods should be logged in order not to break the user space
analysis tool. Lv Zheng.
