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.

The dtrace provider for UDP-Lite is modeled after the UDP provider.
This fixes the bug that UDP-Lite packets were triggering the UDP

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.

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.

We can't link an executable using -m32 until the lib32 phase of a
buildworld, though the build works fine when executing make from
cddl/usr.sbin/dtrace/tests. Some other solution will need to be found.
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.

Both test suites require more memory than my amd64 VM using
GENERIC-NODEBUG can provide and reliably panic it with OOM issues in
dtrace(4).
Some of the testcases fail, but this at least bypasses the panic behavior
on platforms that don't have enough resources

Summary of changes:
- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
namespacing is kept with FILES appropriately, and that this shouldn't need
to be repeated if the namespace changes -- only the definition of PACKAGE
needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
`tests`. In the event we get to the point where things can be split up
enough in the base system, it would make more sense to group the tests
with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into
bsd.tests.mk
- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash
and lib/libc/tests/net/getaddrinfo
- Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup)
Document the proposed changes in share/examples/tests/tests/... via examples
so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of
replacing FILES. share/mk/bsd.README didn't seem like the appropriate method
of communicating that info.

script. This reimplementation is much simpler than dtest.pl and is more
amenable to being run under Kyua - dtest.pl writes error output to a
temporary directory that is deleted when the run finishes, making it hard
to debug test failures. This change also removes the test suite's dependency
on perl.
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.
