* core.c (dis_asm_read_memory), defs.h, gdbtk.c (gdb_disassemble),

	* core.c (dis_asm_read_memory), defs.h, gdbtk.c (gdb_disassemble),
	top.c :  Get rid of dis_asm_read_memory_hook.  We can now call the
	disassemblers directly and have no need for this hook anymore.
	* defs.h, printcmd.c:  Make print_insn be static.

	* ser-go32.c (dos_comisr):  Make this 8 bit clean.
	* (dos_open dos_close):  Allow multiple opens to the same device.
	Use a ref count to prevent unwanted deallocations.
	* sparcl-tdep.c:  Put #ifdefs around all socket stuff to make GO32
	happy.
	* (sparclite_ops):  Switch to download_stratum.
	* target.h (enum strata):  Move download_stratum before
	process_stratum so that executable targets get pushed on top of
	download targets.
