Interpreter: Add additional debug info for an error case.

Emit the name of the namespace node for the error case when
there is no subobject attached to the node.
Linuxize: Cleanup format conversions.

As AcpiSrc supports the case that the input/output files are the same file,
ACPICA_TMP is not useful for divergence.sh any more.
This patch cleans up ACPICA_TMP by invoking new linuxize_format() function
provided by libacpica.sh.  A similar cleanup is also done in gen-repo.sh in
this patch. Lv Zheng.
AcpiSrc: Cleanup spaces after special macro invocations.

There are still spaces in the linuxized ACPICA files after special macro invocations.
This patch refines the cleanup code for "acpisrc -i" mode.  Note that indent treats
comments and pre-processor directives as spaces, thus we need to skip them.

Before applying this patch, cleanup code will search from keyword back to end of line and
wipe spaces between them.
After applying this patch, cleanup code will search to the end of the macro invocations,
then skip "empty lines", "comments" and "pre-processor directives", then wipe the spaces
between the new line and the first non-spaces characters.  Lv Zheng.
ASLTS: Fixes for slack mode failures.

This patch fixes the failure reported for the following ASLTS test:
 exceptions:exc_result2:m692-Inc-Exc (32/64 bit slack mode)
 exceptions:exc_result2:m692-Dec-Exc (32/64 bit slack mode)

The test cases expect exceptions generated for mismatched types during
implicit conversions happened to Increment/Decrement opcodes.  And the
[Unitialized] object could never be converted into object with any other
types.  But the "FAIL" is emitted due to the slack mode which converts
[Uninitialized] operand into 0-valued Integer, thus no type mismatch can be
examined for these test cases.

The command to confirm this test:
 aslts.sh -m s32 -m s64 -c exc_result2 -t
The result in __STATUS_OF_TESTS before applying this fix:
 ":STST:exceptions:exc_result2:m692-Inc-Exc:FAIL:Errors # 02 00 00 00:"
 ":STST:exceptions:exc_result2:m692-Dec-Exc:FAIL:Errors # 02 00 00 00:"
The result in __STATUS_OF_TESTS after applying this fix:
 ":STST:exceptions:exc_result2:m692-Inc-Exc:PASS:"
 ":STST:exceptions:exc_result2:m692-Dec-Exc:PASS:"

Update .gitignore file for new project.

Added unix generation for the acpiexamples project.
Utilities: Cleanup declarations of the AcpiGbl_DebugFile global.

This global is acting as an OSL global variable, implemented in the
oswinxf.c and osunixxf.c.
This patch cleans up the definition of this variable so that new utilities
do not need to define it in order to link. Lv Zheng.
