Redirect program's stdout and stderr to /dev/null

2003-02-20  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-filter-search.c (run_command): Redirect program's stdout
	and stderr to /dev/null

	* camel-filter-driver.c (pipe_to_system): Redirect the program's
	stderr to /dev/null
	(pipe_to_system): Write the pipe to a mem stream and use the mem
	stream in the parser. Also, when setting an exception get the
	errno from the parser so we can give more info about the error to
	the user.
