Hi,

The disassembler files should be updated to get newer instructions
supported. This is currently not easy because the *-dis.c files are
concatenated using several files from binutils. There are some Qemu
specific changes.

The first patch introduces a new directory "dis", moves sparc-dis.c
there, and splits it to three files as used in binutils: sparc-dis.c,
sparc-opc.c and sparc.h.

The second patch updates the files from binutils 2.18. The real
changes from 2002 binutils to current are not that large, but there is
some code movement and I changed tabs to spaces at one point. The
license changes from GPL v2 to v3.

I can introduce more staging patches if necessary. Comments?
