Attached is a patch against GDB-6.4 that enables demangling of symbols
generated by DMD[1] and GDC[2].

The infrastructure part (c-lang.c, defs.h, d-lang.h, dwarf2read.c,
language.c, Makefile.in, symfile, syntab.c, dwarf2.h) is based on John
Demme's work[3][4].

The pluggable demangler (gdb/demangle_d/*) was written completely form
scratch and isn't based on John's work and supports templates and - to a
certain extend - nested functions and types.
