Modified Files:
	syssrc/sys/kern: tty_pty.c

Log Message:
change DEFAULT_MAXPTYS to 256
make all local variables static
use simplelocks - we really need only mutexes, full locks are not necessary
update couple of comments to be more accurate

add function pty_maxptys(), which provides a safe way to get&set maxptys - this
	also supports setting maxptys to lower than current value, if the
	value is lower or equal current number of ptys
