This commit adds tests for the default_permissions and push_symlinks_in
mount options. It doesn't add tests for allow_other, because I'm not sure
how that will interact with Kyua (the test will need to drop privileges).
All of the other mount options are undocumented.

This required changing the way that all operations are mocked. Previously
MockFS::process had one input argument and one output argument. Now, it
returns a vector of zero or more responses. This allows tests to simulate
conditions where the filesystem daemon has a queue depth > 1.

The netipsec and pf tests have a number of common test functions. These
used to be duplicated, but it makes more sense for them to re-use the
common functions.

This is marginally faster than using an environment check in each test case.
Also, if the global check fails then all of the tests are skipped. Oddly,
it's not possible to skip a test in any other way.
Also, allow the test to run as a normal user if vfs.usermount=1 and
/dev/fuse is accessible.

It only tests the kernel portion of fuse, not the userspace portion (which
comes from sysutils/fusefs-libs). The kernel-userspace interface is
de-facto standardized, and this test suite seeks to validate FreeBSD's
implementation.
It uses GoogleMock to substitute for a userspace daemon and validate the
kernel's behavior in response to filesystem access. GoogleMock is
convenient because it can validate the order, number, and arguments of each
operation, and return canned responses.
But that also means that the test suite must use GoogleTest, since
GoogleMock is incompatible with atf-c++ and atf.test.mk does not allow C++
programs to use atf-c.
This commit adds the first 10 test cases out of an estimated 130 total.

Generate a fragmented packet with different header chains, to provoke

Without the fix this will trigger a panic.

pfctl has an issue with 'set skip on <group>', which causes inconsistent
behaviour: the set skip directive works initially, but does not take
effect when the same rules are re-applied.

When building with KCOV enabled the compiler will insert function calls
to probes allowing us to trace the execution of the kernel from userspace.
These probes are on function entry (trace-pc) and on comparison operations
(trace-cmp).
Userspace can enable the use of these probes on a single kernel thread with
an ioctl interface. It can allocate space for the probe with KIOSETBUFSIZE,
then mmap the allocated buffer and enable tracing with KIOENABLE, with the
trace mode being passed in as the int argument. When complete KIODISABLE
is used to disable tracing.
The first item in the buffer is the number of trace event that have
happened. Userspace can write 0 to this to reset the tracing, and is
expected to do so on first use.
The format of the buffer depends on the trace mode. When in PC tracing just
the return address of the probe is stored. Under comparison tracing the
comparison type, the two arguments, and the return address are traced. The
former method uses on entry per trace event, while the later uses 4. As
such they are incompatible so only a single mode may be enabled.
KCOV is expected to help fuzzing the kernel, and while in development has
already found a number of issues. It is required for the syzkaller system
call fuzzer [1]. Other kernel fuzzers could also make use of it, either
with the current interface, or by extending it with new modes.
A man page is currently being worked on and is expected to be committed
soon, however having the code in the kernel now is useful for other
developers to use.

There are currently 38 regression tests, which test the kernel control ABI
exposed by netmap to userspace applications:
1: test for port info get
2-5: tests for basic port registration
6-9: tests for VALE
10-11: tests for getting netmap allocator info
