When script(1) reads EOF from input it starts spinning on zero-byte
reads eating 100% CPU. Fix this by skipping select on STDIN after
reading EOF -- permanently if STDIN is not terminal and for one second
if it is.
Also after reading EOF from STDIN we have to pass it to the program
being scripted. The previous approach was to write zero bytes into the
pseudo-terminal. This does not work because zero-byte write does not
have any effect on read. Fix this by sending VEOF instead.

When a status pointer is passed in mfi_dcmd_command does not return an

Cache failing and opened catalogs in catopen() and related functions.
Continuous catopen() calls cause 4 failig stat(2) each, which means a lot
of overhead. It is also a good idea to keep the opened catalogs in the memory
to speed up further catopen() calls to the same catalog since these catalogs
are not big at all. In this case, we count references and only free() the
allocated space when the reference count reaches 0. The reads and writes to
the cache are syncronized with an rwlock when these functions are called from

vge(4) hardwares poll media status and generates an interrupt
whenever the link state is changed. Using software based polling
for media status tracking is known to cause MII access failure
under certain conditions once link is established so vge(4) used to
rely on link status change interrupt.
However DEVICE_POLLING completely disables generation of all kind
of interrupts on vge(4) such that this resulted in not detecting
link state change event. This means vge(4) does not correctly
detect established/lost link with DEVICE_POLLING. Losing the
interrupt made vge(4) not to send any packets to peer since vge(4)
does not try to send any packets when there is no established link.
Work around the issue by generating link state change interrupt
with DEVICE_POLLING.
Addendum to the original commit message:
This is mostly useful to protect kdb_trap() from concurrent entry as it
doesn't have any protection like e.g. panic(9) has. Even if kdb_trap()
had that protection there would still be a need for protection
between concurrect panic() and kdb_trap() entries. That protection
could be implemented externally, but doing it in generic_stop_cpus()
seems to be OK as well (stopping CPUs on panic is in the works).
