Add debug tracing support during certain AML method execution.
Four more module parameters are created under /sys/module/acpi/parameters/:
trace_method_name: the AML method name that user wants to trace
trace_debug_layer: the temporary debug_layer used when tracing the method.
Using 0xffffffff by default if it is 0.
trace_debug_level: the temporary debug_level used when tracing the method.
Using 0x00ffffff by default if it is 0.
trace_state: The status of the tracing feature.
"enabled" means this feature is enabled
and the AML method is traced every time it's executed.
"1" means this feature is enabled and the AML method
will only be traced during the next execution.
"disabled" means this feature is disabled.
Users can enable/disable this debug tracing feature by
"echo string > /sys/module/acpi/parameters/trace_state".
"string" should be one of "enable", "disable" and "1".

cosmetic only
Make "module name" actually match the file name.
Invoke with ';' as leaving it off confuses Lindent and gcc doesn't care.
Fix indentation where Lindent did get confused.

Add ACPI debug attributes in sysfs.
/proc/acpi/debug_layer && debug_level are deprecated by
/sys/module/acpi/parameters/debug_layer && debug_level.
NOTE: The operations to them are quite the same.
E.g. if you want to enable ACPI_DB_INFO, ACPI_DB_WARN,
ACPI_DB_ERROR and disable the others,
#echo 0x13 >/sys/module/acpi/parameters/debug_level is OK,
and a boot option "acpi.debug_level = 0x13" also works.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
