JDK: Full Debug Symbols

This is a placeholder bug for the Full Debug Symbols project.
Full Debug Symbols needs to be added to the 'jdk' repo with
the same features that were added to the 'hotspot' repo.

The feature is enabled with FULL_DEBUG_SYMBOLS build flag.
The default value will be FULL_DEBUG_SYMBOLS=1 and the
feature can be disabled by FULL_DEBUG_SYMBOLS=0 for OPT
builds.

The ZIPing of debug info files is enabled with the
ZIP_DEBUGINFO_FILES flag. The default value will be
ZIP_DEBUGINFO_FILES=1 and the sub feature can be
disabled by ZIP_DEBUGINFO_FILES=0 for all builds.

Because the 'jdk' contains technologies that are managed
and developed by different teams, FDS on Linux and Solaris
will only initially be supported by a subset of libraries
and programs. The LIBRARY_SUPPORTS_FULL_DEBUG_SYMBOLS and
PROGRAM_SUPPORTS_FULL_DEBUG_SYMBOLS make flags are used
in Makefiles to indicate which libraries and programs
support FDS on Linux and Solaris.

Windows has supported Full Debug Symbols since JDK1.4.1
so the LIBRARY_SUPPORTS_FULL_DEBUG_SYMBOLS and
PROGRAM_SUPPORTS_FULL_DEBUG_SYMBOLS build flags have
no effect on a Windows build.
