(and there was much rejoycing)

This patch eliminates the last remenants of the global variables:

	deprecated_tm_print_insn
	deprecated_tm_print_insn_info

Everything now goes through disasm.c.  Note that all architectures 
currently need to supply TARGET_PRINT_INSN.

There's one "future work" item - eliminate TARGET_PRINT_INSN.  GDB's 
multi-arch needs to be a way to map an address onto an arch/mach.  Once 
there opcodes/ (with some interface fudging) can be called directly and 
it can select the disassembler (well in theory).

Anyway, I'll look to commit this in a few days.
