1. Copy a NULL-terminated string into a fixed-length buffer, and
2. copyout that buffer to userland,
we really ought to
0. Zero the entire buffer

Add new solaris slice type
Don't prefix /dev if it is already an absolute path.
Use correct open mode (possibly r/w) if we resort to opening a slice.

Some changes to intr_execute_handlers():
- Fix NULL pointer dereferences caused when an ithread or a handler is
NULL which happens when a stray interrupt triggers after the respective
device interrupt was torn down.
- Remove the critical section around INTR_FAST handlers which actually
was a nested critical section. Both tl0_intr() and tl1_intr() already
enter a critical section for calling intr_execute_handlers().

- Add a workaround for a bug in BlackBird CPUs (said to be part of the
SpitFire erratum #54) which can cause writes to the TICK_CMPR register
to fail. This seems to fix the dying clocks problem reported by jhb@
and kris@.
- In tick_init() just use tick_stop() for stopping the tick interrupts
until a proper handler is set up later. This also stops the system
tick interrupt on USIII systems earlier.
- Some minor changes, e.g. use FBSDID, remove unused headers, etc.

Add the vm.exec_map_entries tunable and read-only sysctl, which controls
the number of entries in exec_map (maximum number of simultaneous execs
that can be handled by the kernel). The default value of 16 is
insufficient on heavily loaded machines (particularly SMP machines), and
if it is exceeded then executing further processes will generate a SIGABRT.
This is a workaround until a better solution can be implemented.

Fix panics with misconfigured routing:
- Backout previous revision, the check is useless.
- Turn node to queue mode, since it is edge node.

UCS_RXSTOP flag so that it always tracks whether or not the receive
pipe is stopped. This ensures that we do not attempt to start the
same transfer twice, and it allows ucomstop() to skip the restarting
of the read pipe if it was not originally running, such as when
called indirectly from ucomreadcb().
Approved by: re (kensmith)
Add rudimentary man pages for kernel options sched_4bsd and sched_ule,
which document some of the sysctls available for configuring 4bsd, some
of the bullet features of ule, and that ule is considered experimental
still.
Fix small spelling error.

When a packet has been reinjected into ipfw(4) after dummynet(4) processing
we have a non-NULL args.rule. If the same packet later is subject to "tee"
rule, its original is sent again into ipfw_chk() and it reenters at the same
rule. This leads to infinite loop and frozen router.
Assign args.rule to NULL, any time we are going to send packet back to
ipfw_chk() after a tee rule. This is a temporary workaround, which we
will leave for RELENG_5. In HEAD we are going to make divert(4) save
next rule the same way as dummynet(4) does.
