88f39e8e95 Introduce no-op nosup fifo kqueue filter and detach routine, which are
used when a read filter is requested on a write-only fifo descriptor, or
a write filter is requested on a read-only fifo descriptor.  This
permits the filters to be registered, but never raises the event, which
causes kqueue behavior for fifos to more closely match similar semantics
for poll and select, which permit testing for the condition even though
the condition will never be raised, and is consistent with POSIX's notion
that a fifo has identical semantics to a one-way IPC channel created
using pipe() on most operating systems.

The fifo regression test suite can now run to completion on HEAD without
errors.

456068c703 Comment test_lseek().
Add test_kqueue(), which registers and unregisters various kqueue filter
types on a fifo in order to make sure that EVFILT_READ, EVFILT_WRITE can
be registered, and that EVFILT_NETDEV can't be registered.  For now, we
don't test that EVFILT_VNODE can be registered on fifos, as that has been
broken at some point.

831a62e7e5 - Fix the locking in dsp.c to prevent a LOR (AFAIK not on the LOR page).
- Remove an assertion in sound.c, it's not needed (and causes a panic now).
  From the conversation via mail between glebius and Ariff:
  ---snip---
  > Well, but which mutex protects now? Do we own anything else
  > in pcm_chnalloc()? I see some queue(4) macros in pcm_chnalloc(),
  > they should be protected, shouldn't they?
  Queue insertion/removal occur during
     1) driver loading (which is pretty much single thread /
        sequential) or unloading (mutex protected, bail out if there is
        any channel with refcount > 0 or busy).
     2) vchan_create()/destroy(), (which is *sigh* quite complicated), but
        somehow protected by 'master'/parent channel mutex. Other
        thread cannot add/remove vchan (or even continue traversing
        that queue) unless it can acquire parent channel mutex.

48afebb83d When a request is made to register a filter on a fifo that doesn't
apply to the fifo (i.e., not EVFILT_READ or EVFILT_WRITE), reject
it as EINVAL, not by returning 1 (EPERM).

1423f2f54c Further updates to fifo_io regression test:
- Teach fifo_io about kqueue monitoring of fifo file descriptor status,
  and add test cases for kqueue to match existing case for poll and
  select.  Add a new cleanup routine, cleanfifokq(), for use in tests that
  use kqueues.  kqueue_setup() sets up kqueue sessions, and kqueue_status()
  returns file descriptor status.

- Correct a bug in select handling relating to the nfds argument, which
  was incorrect so resulted in select occuring on the wrong file descriptor,
  and possible false positive/negative results.

- Clarify error reporting in one byte write+read tests to distinguish
  errors in the after case from the before case.

114538d85b Remove DFLAG_SEEKABLE from fifo file descriptors: fifos are not seekable
according to POSIX, not to mention the fact that it doesn't make sense
(and hence isn't really implemented).  This causes the fifo_misc
regression test to succeed.

doesn't).

6dd84b0bdc Only poll the fifo for read events if the fifo is attached to a readable
file descriptor.  Otherwise, the read end of a fifo might return that it
is writable (which it isn't).

Only poll the fifo for write events if the fifo attached to a writable
file descriptor.  Otherwise, the write end of a fifo might return that
it is readable (which it isn't).

In the event that a file is FREAD|FWRITE (which is allowed by POSIX, but
has undefined behavior), we poll for both.

845e8e827b After going to some trouble to identify only the write-related events
to poll the write socket for, the fifo polling code proceeded to poll
for the complete set of events.  Use 'levents' instead of 'events' as
the argument to poll, and only poll the write socket if there is
interest in write events.
