Lv Zheng 2cf9f5bcc8 ACPICA: Add acpi_update_interfaces() public interface
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.

Bob Moore ba494beeaa ACPICA: AcpiSrc: Fix some translation issues for Linux conversion
Fixes issues like this:

i_aSL -> iASL
00-7_f -> 00-7F
local_fADT -> local_FADT
execute_oSI -> execute_OSI

Also, in function headers, the parameters are now translated to
lower case (with underscores if necessary.)

Lin Ming b0ed7a915a ACPICA/ACPI: Add new host interfaces for _OSI support
Adds install/remove interfaces so that the host can dynamically
alter the global _OSI table. Also adds support for _OSI handlers.
Additional support: new debugger command (osi), and test support in
the acpiexec utility. Adds new file, utilities/utosi.c.
ACPICA bugzilla 836.

The Linux OSL _OSI code is also changed.
acpi_osi_setup can't call acpi_install/remove_interface because ACPICA
is not initialized yet at this early time.
So we just save the osi string in acpi_osi_setup and will handle it
later in a new function acpi_osi_setup_late.
