to increase it broke the ability to write large chunks of memory
with m68k-stub and i386-stub. Now we only use more than 400 on
machines where we need that much to write the registers.
* remote.c (remote_write_bytes): Eliminate possible abort(). The

it is handled by MAXBUFBYTES, which the caller uses.
* m68k-stub.c: Add comments about trap #1 and trap #8 instructions.
