ACPICA: Fix unmerged debugger divergences.

Debugger improvements in ACPICA are always ignored by ACPICA Linux
release.  This will lead to divergences between Linux and ACPICA.
This patch fixes such unmerged debugger updates.

Following patches are included:
1. Fixed a couple compiler warnings for extra extern

2. Cleanup for internal Reference Object.
   Wed, 27 Aug 2008 10:11:30 -0700
3. Debugger: Lock method args for multithread command.
   Fri, 24 Apr 2009 12:28:49 -0700
4. Debugger: Add max count argument for Batch command.
   Tue, 29 Sep 2009 12:31:58 -0700
5. Add new host interfaces for _OSI support.

6. Increase debugger buffer size for method return objects.
   Wed, 17 Nov 2010 13:48:30 -0800
7. Debugger: Add command to display status of global handlers.
   Tue, 25 Jan 2011 13:47:58 -0800
8. Debugger: Split large dbcmds.c file.
