[patch/mips] Remove remote-mips output limit

[Andrew Cagney <ac131313 at cygnus dot com>]

FYI,

The attatched changes how remote-mips treates stray characters from
target.  Instead of assuming that stray characters are bad or indicate a
problem, it instead assumes that they are normal output.  Only when
unprintable characters start to be received does it take notice.

This, if nothing else, removes a somewhat arbitrary limit to the number
of characters that a remote pmon/mips/... target could print.

	enjoy,
		Andrew

	* remote-mips.c: Include <ctype.h>
 	(mips_receive_header): Write printable characters to gdb_stdtarg
 	instead of gdb_stdlog.  Only count non-printables as invalid.
	(mips_syn_garbage): Reduce to 10.
