MFC note: tests/sys/kern/coredump_phnum_test.sh changes omitted

MFC r322214:

Make test scripts under tests/... non-executable

Executable bits should be set at install time instead of in the repo.
Setting executable bits on files triggers false positives with Phabricator.

MFC r312120:

Fix warnings

- Staticize test_num
- Promote i to size_t to deal with -Wsign-compare issues

Tested with: clang, gcc, gcc49

MFC r312164:

Fix -Wformat issue

Use %zu for printing out results from nitems, as it's size_t based

MFC r305916,r305918:

r305916:

Make sure $TMPDIR is created with 0755 permissions

This is required to ensure that the temporary script can be executed,
as the default mode is apparently too restrictive

r305918:

Only chmod $TMPDIR if it's not /tmp

This is a safety belt to ensure that the /tmp sticky bit stuff doesn't
get whacked by accident if someone runs the script outright

MFC r305357:

Skip testcases 9/10 if jail(8) isn't installed

These testcases require jail support

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Merge ^/user/ngie/release-pkg-fix-tests to unbreak how test files are installed
after r298107

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.

Merge the projects/release-pkg branch to head.

This allows packaging the base system with pkg(8), including
but not limited to providing the ability to provide upstream
binary update possibilities for non-tier-1 architectures.

This merge is a requirement of the 11.0-RELEASE, and as such,
thank you to everyone that has tested the project branch.

Documentation in build(7) etc. is still somewhat sparse, but
updates to those parts will follow.

DIRDEPS_BUILD: Connect MK_TESTS.

Delete the comment about running `test_libugidfw_strings` before testing
`mac_is_present` so it doesn't accidentally confuse people

Move mac_bsdextended check up before running the test_libugidfw_strings testcases

I realize that these tests could be run before mac_bsdextended is loaded, but
it would overcomplicate things to special case handle the testcases before doing
the mac_bsdextended(4) feature check

The testcases will be split up so they can be run separately in the near future

Integrate tools/regression/mac/mac_bsdextended and
tools/regression/mac/mac_portacl into the FreeBSD test suite as
tests/sys/mac/bsdextended and tests/sys/mac/portacl, respectively
