Add the kernel-level tests developed by Lukasz Strzygowski as part of the
atfify GSoC 2008 project.

Test kernel/kqueue/t_timer, subtests abstime, basic_timer and timer_units
often fail when run on QEMU because QEMU misses clock interrupts.

Always check timespec against expected "tv_sec" and use an "4 * tv_sec"
upper bound when run under QEMU.

Now becomes part of PR kern/43997 "Kernel timer discrepancies".

Fix a regression introduced in kern_event.c,v 1.129 that would cause
"udata" to get clobbered on ONESHOT events, and add a unit test for it.
Reported by martin@ (manifested in his case as a KASSERT() firing when
running unit tests in COMPAT_NETBSD32).

Add support for the EVFILT_EMPTY filter, which is activated when the
write buffer associated with the file descriptor is empty. This is
currently implemented only for sockets, and is intended primarily to
provide visibility to applications that all previously written data
has been acknowledged by the TCP layer on the receiver. Compatible
with the same filter in FreeBSD.

Add support for the NOTE_SECONDS, NOTE_MSECONDS, NOTE_USECONDS,
NOTE_NSECONDS, and NOTE_ABSTIME filter flags to EVFILT_TIMER,
API-compatible with the same in FreeBSD.

Add a test case for the race condition in PR kern/50094, modeled after
the Go run-time scenario described in the PR.

tests: Fix false positives due to race b/w connect(2) and accept(2)

For kernel/kqueue/t_empty and net/net/t_tcp, there were no sync ops
b/w connect(2) and accept(2) for non-blocking socket pair on host
(rump is not used).

As a result, accept(2) can fail immediately with EAGAIN, when
kernel-side routines for connect(2) and accept(2) are processed in
different CPU cores.

1-sec sleep(3) between two syscalls seems to mitigate this problem
as far as I can see, although this should not be a perfect solution...

Thanks ozaki-r@ for discussion.

branches: 1.4.2; 1.4.4;
The knotes for EVFILT_SIGNAL and EVFILT_PROC are maintained on a single
per-process list, and kern_event.c,v 1.129 has several KASSERT()s in
various code paths that process this list related to the mixing of these
two knote types. This new unit test is designed specifically to exercise
those KASSERT()s and thus validate their assumptions.

Overhaul of the EVFILT_VNODE kevent(2) filter:

- Centralize vnode kevent handling in the VOP_*() wrappers, rather than
forcing each individual file system to deal with it (except VOP_RENAME(),
because VOP_RENAME() is a mess and we currently have 2 different ways
of handling it; at least it's reasonably well-centralized in the "new"
way).
- Add support for NOTE_OPEN, NOTE_CLOSE, NOTE_CLOSE_WRITE, and NOTE_READ,
compatible with the same events in FreeBSD.
- Track which kevent notifications clients are interested in receiving
to avoid doing work for events no one cares about (avoiding, e.g.
taking locks and traversing the klist to send a NOTE_WRITE when
someone is merely watching for a file to be deleted, for example).

In support of the above:

- Add support in vnode_if.sh for specifying PRE- and POST-op handlers,
to be invoked before and after vop_pre() and vop_post(), respectively.
Basic idea from FreeBSD, but implemented differently.
- Add support in vnode_if.sh for specifying CONTEXT fields in the
vop_*_args structures. These context fields are used to convey information
between the file system VOP function and the VOP wrapper, but do not
occupy an argument slot in the VOP_*() call itself. These context fields
are initialized and subsequently interpreted by PRE- and POST-op handlers.
- Version VOP_REMOVE(), uses the a context field for the file system to report
back the resulting link count of the target vnode. Return this in tmpfs,
udf, nfs, chfs, ext2fs, lfs, and ufs.

Adjusts tests after import of atf-0.12:

- The use.fs property is gone.
- Mark the tests/fs/t_create:attrs test as broken when using the default
unprivileged-user:_atf setting. This probably deserves a fix somehow
but I'm not sure at this point.

atf-0.9 introduces an use.fs test-case property to allow tests to write to
their work directory. The purpose is to be able to know which tests intend
to touch the file system and to allow a minor optimization in atf-run.

Define use.fs=true for all those tests requiring it. (This highlights that
some tests currently require modifying the file system but conceptually
they shouldn't be... which leaves room for further improvements/cleanups
later :-)
