c573e654b7 Add OS layer ACPI mutex and threading support. 
- Temporary fix a bug of Intel ACPI CA core code.
 - Add OS layer ACPI mutex support.  This can be disabled by
   specifying option ACPI_NO_SEMAPHORES.
 - Add ACPI threading support.  Now that we have a dedicate taskqueue for
   ACPI tasks and more ACPI task threads can be created by specifying option
   ACPI_MAX_THREADS.
 - Change acpi_EvaluateIntoBuffer() behavior slightly to reuse given
   caller's buffer unless AE_BUFFER_OVERFLOW occurs.  Also CM battery's
   evaluations were changed to use acpi_EvaluateIntoBuffer().
 - Add new utility function acpi_ConvertBufferToInteger().
 - Add simple locking for CM battery and temperature updating.
 - Fix a minor problem on EC locking.
 - Make the thermal zone polling rate to be changeable.
 - Change minor things on AcpiOsSignal(); in ACPI_SIGNAL_FATAL case,
   entering Debugger is easier to investigate the problem rather than panic.

eb5b463449 Fix error checking about device state transition from D0 to D3. 
Turn off the resources listed in _PR0 to go to D3 if we don't have _PR3/_PS3.

dfcd35dd08 Whoops; we get an ACPI_OBJECT back from evaluating a method, not 
an ACPI_OPERAND_OBJECT.  Fix this so that the power resource type
can be properly checked, and we can get the system level and
resource order.

2b80a316c3 This was only half-implemented when I committed it, and certainly didn't 
work.  Now it's implemented and seems to work.

import.

c5ba0be495 Sync to my work in progress: 
- Reorder the acpi_* functions in a sensible fashion
 - Add acpi_ForeachPackageObject and acpi_GetHandleInScope
 - Use the new debugging layer/level names
 - Implement most of the guts of the acpi_thermal module; passive cooling
   isn't there yet, but active cooling should work.
 - Implement power resource handling (acpi_powerres.c)

This compiles and mostly works, but my test coverage is small, so feedback
is welcome.
