DTrace test: Add a new keyword SKIPCI to gentest.sh

This is for marking a test case is flakey and should not be executed in
the CI environment.

Enable creation of static userspace probes in incremental builds.

To define USDT probes, dtrace -G makes use of relocations for undefined
symbols: the target address is overwritten with NOPs and the location is
recorded in the DOF section of the output object file. To avoid link
errors, the original relocation is destroyed. However, this means that
the same input object file cannot be processed multiple times, as
happens during incremental rebuilds. Instead, only set the relocation
type to NONE, so that all information required to reconstruct USDT
probes is preserved.

dtrace tests: Support globbing for excludes

Downstream this makes skipping tests like common/ip/tst.*sctp*.ksh simpler.

Add a dtrace provider for UDP-Lite.

The dtrace provider for UDP-Lite is modeled after the UDP provider.
This fixes the bug that UDP-Lite packets were triggering the UDP
provider.
Thanks to dteske@ for providing the dwatch module.

Improve TCP related tests for dtrace.

Ensure that the TCP connections are terminated gracefully as expected
by the test. Use appropriate numbers for sent/received packets.
In addition, enable tst.localtcpstate.ksh, which should pass, but
doesn't until https://reviews.freebsd.org/D16369 is committed.

Fix the UDP tests for dtrace.

The code imported from opensolaris was depending on ping supporting
UDP for sending probes. Since this is not supported by ping on FreeBSD
use a perl script instead.
The remote test requires the usage of ksh93, so state that in the
sheband.
Enable the local test, but keep the remote test disabled, since it
requires a remote machine on the LAN.

Mark uctf/err.user64mode.ksh as EXFAIL for now.

Annotate pragma/err.invalidlibdep.ksh as EXFAIL.

The test creates a D library with a "depends_on library" pragma
referencing a non-existent library, and expects compilation to fail.
However, as far as I can tell, libdtrace is supposed simply abort
compilation of the library in this case, and continue. This behaviour
is desirable when adding libraries which depend on optional KLDs, for
example.

Fix a typo that snuck in with r283024, and remove the EXFAIL annotation from

Add infrastructure to integrate the DTrace test suite with Kyua.

For each test category, we generate a script containing ATF test cases for
the tests under that category. Each test case simply runs dtest.pl (the
upstream test harness) with the corresponding test files. The exclude.sh
script is used to record info about tests which should be skipped or are
expected to fail; it is used to generate atf_skip and atf_expect_fail calls.
The genmakefiles.sh script can be used to regenerate the test makefiles when
new tests are brought it from upstream.

The test suite is currently not connected to the build as there is a small
number of lingering test issues which still need to be worked out. In the
meantime however, the test suite can be easily built and installed
manually from cddl/usr.sbin/dtrace/tests.
