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.
