The original commit 242b2287cd "ACPICA:
expose OSI version" triggers build errors in ACPICA when it is back
ported. The patch removes the divergences between Linux and upstream
ACPICA resulting from that.

Add new API to allow OSPM to disable/enable specific types of _OSI
interface strings.
ACPICA does not have the knowledge about whether an _OSI interface
string is an OS vendor string or a feature group string and there
isn't any API interface to allow OSPM to install a new interface
string as a feature group string.
This patch simply adds all feature group strings defined by ACPI
specification into the acpi_default_supported_interfaces with
ACPI_OSI_FEATURE flag set to fix this gap. This patch also adds
codes to keep their default states as ACPI_OSI_INVALID before the
initialization and after the termination.

Conflicts:
include/acpi/actypes.h (with commit 242b228)
Expose acpi_gbl_osi_data so that code outside of ACPICA can check
the value of the last successfull _OSI call. The definitions for
OSI versions are moved to actypes.h so that other components can
access them too.
Based on a patch from Matthew Garrett which in turn was based on
an earlier patch from Seth Forshee.

ACPI_EVENT_FLAG_HANDLE is a flag for acpi_event_status.
When it is set, it indicates that the ACPI event,
either GPE or fixed event, is associated with a handler.

This patch reduces the source code diff between Linux and ACPICA by
cleaning the comments that already have been updated in ACPICA.
There is no extra indentation done in this patch. Even the empty line
deletions and insertions are also splitted into another cleanup patch so
that this patch can be easily reviewed, and the binary differences can be
held to a lowest level.

_GTS and _BFS were added to the suspend/resume flow
in the ACPI 2.0 specification.
Linux dutifully implemented _GTS and _BFS.
We discovered that it was rarely seen in systems
in the field. Further, some of those systems had
AML so bogus that it could never work -- proof that
no other operating system supports _GTS and _BFS.
So we made _GTS and _BFS optional via modparam,
and disabled them by default.
But we've had to complicate some code to keep
this support in the kernel, as these methods are defined
to be evaluated very close to sleep entry and exit.
Indeed, no other AML is ever evaluated with interrupts off.
We have submitted a proposal for _GTS and _BFS
to be officially removed from the ACPI specification
on the next revision. Here we remove it from Linux.
