	syssrc/sys/kern: kern_sysctl.c tty_pty.c
	syssrc/sys/sys: sysctl.h

Log Message:
allocate pty kernel structures on demand at run-time - this allows
to support arbitrary number of ptys without need of kernel recompile
(the extra device special files in /dev/ still need to be created, of course)

upper limit of supported ptys is controlled via new sysctl variable
kern.maxptys (KERN_MAXPTYS), which is raise-only and defaults to 512.
