Add support for reading Windows PDB debug info (symbols and line
numbers) when Valgrind is running Wine. Modified version of a
patch by John Reiser (vgsvn+wine-load-pdb-debuginfo.patch) with
extensions to read a second format of line number tables.
Wine uses a new client request, VG_USERREQ__LOAD_PDB_DEBUGINFO,
to tell Valgrind when to read PDB info. Wine's implementation
of module loading is vastly different from that used by
ld-linux.so, and it is too difficult to recognize what is going
on just by observing the calls to mmap and mprotect.
