Fixed a bug in kstrncpy() that caused mayhem whenever the buffer to be copied into was the same size as the source string - it will keep on filling with zeroes forever. This was a signed/unsigned bug, fixed by making the kstrncpy argument ssize_t instead of size_t. This bug was triggered by Chris Young <teddga@earthlink.net>, by dazzling coincedence - changing OS_VERSION into something with one more character (exactly the same size as the buffer in the kinfo struct). Also noticed that the kstrncpy() call didn't null-terminate the strings if necessary, also fixed.

Improved NOTIFY system: fixed a minor error, ignore pending notifications on SENDREC system calls. To be done: resource (buffer pool) management; make it structurally impossible to run out of buffers.

New NOTIFY system call! Queued at kernel. Duplicate messages (with same source and type) are overwritten with newer flags/ arguments. The interface from within the kernel is lock_notify(). User processes can make a system call with notify(). NOTIFY fully replaces the old notification mechanism.

. added rm_irq_handler which un-links an irq handler from the linked list of handlers, callable by irqctl system call . workaround for hanging keyboard bug after shutdown.. if key is pressed during or after shutdown procedure, keyboard stops working. It looks like irq 1 gets stuck high if no keyboard reading is done (e.g. because the irq is masked or tty driver has exited). Workaround is to leave irqs enabled until the last second, and call shutdown() immediately after the last driver has stopped (tty task). This way the chance of an unserviced interrupt occuring is negligible.

Added args to lock() and unlock() to tell them apart, for use when lock timing is enabled in minix/config.h. Added phys_zero() routine to klib386.s that zeroes a range of memory, and added corresponding system call.

_PROTOTYPE( void read_tsc, (unsigned long *high, unsigned long *low) );
Added function read_cpu_flags() that returns current cpu flags as a long. This is used to check for interrupts being disabled at the time of a lock() call, if enabled in config.h. The number of times this happens is then counted in the kinfo structure. These events (recursive lockings) lead to nasty race conditions.
