This ensures we start from the actual call site, not the return address.
The latter may actually be in the next consecutive function if the current
function has the __noreturn__ attribute and the alignment is Just Right.
buffer that is smaller in size than the source buffer.
also, there is no guarantee that any of the string components of
the request packet are null terminated.
in some cases, not all elements of the response buffer are
explicitly set. specifically pad and addr. a talk client can spy to
see which host is talking to which host by sending out regular
packets, to which talkd responds without clearing the addr element.

ugly to add -I.../usr.bin to do this. instead, add appropriate
comments in the source to where the files are actually coming from.
- use NETBSDSRCDIR as appropriate
- some minor makefile delint
pointer, in case the caller grew its stack dynamically.
Also beef up the checks to catch cases where the call stack passes
through the exception handling code in locore. In this case, the
frame pointer and program counter are in the trapframe/intrframe.
This eliminates problems where the underlying interrupt handler isn't the
specific layer calling scsipi_complete() for a given scsi transaction.
This avoids deadlocks where the kthread that called the autoconf routines
to configure a scsibus shouldn't be the one put to sleep waiting on a
scsipi_complete (only the scsibus's kthread should be doing that).
To avoid jitter this will force the scsibus's to probe in the order they
run through autoconf (so machines with multiple bus's don't move sd* devices
around on every reboot).
Also, remove a call to path_create() that causes the `prepend' path held by
pkg_perform() to be deleted, causing a core dump later when pkg_perform()
tries to remove it itself.
