Overhaul of RCOMP/GCCE error parsing to fix 8901:
-RCOMP error parser will defer C preprocessor errors to GCCECompiler error parser.
-GCCE error parser is splited into compiler/assembler/linker, calling their counterpart in CDT respectively before handling special cases.
-Updated error messages RCOMP error parser according to latest copy of RCOMP source.
-WINSCW build configuration is using CDT GCC error parser instead of GCCE(for RCOMP C preprocessor error)
Updated test case for error parsing
-Added Bugzilla regression for GCC and make error parser
-Converted test case from hardcoded SDK_ID to picking up the first SDK from device.xml with the build config specified by the test.
-Fixed bug in test harness for input file ends on the last line so it was processed in the same run.
-Fixed bug in test harness for not clearing problem view before each run(for visual cross check).
-Rewritten test harness to use JDOM XML handling(from JAXP), to solve deployment issue in newer JRE.
