Replace hard tabs with four-character indentations, per PEP8.
This is being done to separate stylistic changes from the tests from functional

1. Not all kernels have netmap(4) support. Check for netmap(4) support before
attempting to run the tests via the `PLAIN_REQUIRE_KERNEL_MODULE(..)` macro.
2. Libraries shouldn't be added to LDFLAGS; they should be added to LIBADD
instead. This allows the build system to evaluate dependencies for sanity.
3. Sort some of the Makefile variables per bsd.README.
1., in particular, will resolve failures when running this testcase on kernels
lacking netmap(4) support, e.g., the i386 GENERIC kernels on ^/stable/11 and
^/stable/12.

Final cleanup routines shouldn't be called from testcases; it should be called
from the testcase cleanup routine.
Furthermore, `geli_test_cleanup` should take care of cleaning up geli providers
and the memory disks used for the geli providers. `geli_test_cleanup` will always
be executed whereas the equivalent logic in `geli_test_body`, may not have been
executed if the test failed prior to the logic being run.
Prior to this change, the test case was trying to clean up `$md` twice: once in
at the end of the test case body function, and the other in the cleanup function.
The cleanup function logic was failing because there wasn't anything to clean up
in the cleanup function and the errors weren't being ignored.
This fixes FreeBSD test suite runs after r345864.

This change takes capsicum-test from upstream and applies some local changes to make the
tests work on FreeBSD when executed via Kyua.
The local modifications are as follows:
1. Make `OpenatTest.WithFlag` pass with the new dot-dot lookup behavior in FreeBSD 12.x+.
2. capsicum-test references a set of helper binaries: `mini-me`, `mini-me.noexec`, and
`mini-me.setuid`, as part of the execve/fexecve tests, via execve, fexecve, and open.
It achieves this upstream by assuming `mini-me*` is in the current directory, however,
in order for Kyua to execute `capsicum-test`, it needs to provide a full path to
`mini-me*`. In order to achieve this, I made `capsicum-test` cache the executable's
path from argv[0] in main(..) and use the cached value to compute the path to
`mini-me*` as part of the execve/fexecve testcases.
3. The capsicum-test test suite assumes that it's always being run on CAPABILITIES enabled
kernels. However, there's a chance that the test will be run on a host without a
CAPABILITIES enabled kernel, so we must check for the support before running the tests.
The way to achieve this is to add the relevant `feature_present("security_capabilities")`
check to SetupEnvironment::SetUp() and skip the tests when the support is not available.
While here, add a check for `kern.trap_enotcap` being enabled. As noted by markj@ in
https://github.com/google/capsicum-test/issues/23, this sysctl being enabled can trigger
non-deterministic failures. Therefore, the tests should be skipped if this sysctl is
enabled.
All local changes have been submitted to the capsicum-test project
(https://github.com/google/capsicum-test) and are in various stages of review.

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.

It's been reported that pf doesn't handle running out of available ports
for NAT correctly. It freezes until a state expires and it can find a
free port.
Test for this, by setting up a situation where only two ports are
available for NAT and then attempting to create three connections.
If successful the third connection will fail immediately. In an
incorrect case the connection attempt will freeze, also freezing all
interaction with pf through pfctl and trigger timeout.

Once a signal's siginfo was copied to 'td_si' as part of the signal
exchange in issignal(), it was never cleared. This caused future
thread events that are reported as SIGTRAP events without signal
information to report the stale siginfo in 'td_si'. For example, if a
debugger created a new process and used SIGSTOP to stop it after
PT_ATTACH, future system call entry / exit events would set PL_FLAG_SI
with the SIGSTOP siginfo in pl_siginfo. This broke 'catch syscall' in
current versions of gdb as it assumed PL_FLAG_SI with SIGTRAP
indicates a breakpoint or single step trap.

Re-apply r341665 with format strings fixed.
If we happen to taste a stale mirror component first, don't reject valid,
newer components that have differing metadata from the stale component
(during STARTING). Instead, update our view of the most recent metadata as
we taste components.
Like mediasize beforehand, remove some checks from g_mirror_check_metadata
which would evict valid components due to metadata that can change over a
mirror's lifetime. g_mirror_check_metadata is invoked long before we check
genid/syncid and decide which component(s) are newest and whether or not we
have quorum.
Before checking if we can enter RUNNING (i.e., we have quorum) after a NEW
component is added, first remove any known stale or inconsistent disks from
the mirrorset, rather than removing them *after* deciding we have quorum.
Check if we have quorum after removing these components.
Additionally, add a knob, kern.geom.mirror.launch_mirror_before_timeout, to
force gmirrors to wait out the full timeout (kern.geom.mirror.timeout)
before transitioning from STARTING to RUNNING. This is a kludge to help
ensure all eligible, boot-time available mirror components are tasted before
RUNNING a gmirror.
Add a basic test case for STARTING -> RUNNING startup behavior around stale
