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.

Sponsored by: EMC / Isilon Storage Division

sh: Add limited test for ${#@} and ${#*}.

POSIX leaves the result of expanding ${#@} and ${#*} unspecified, but ensure
it is numeric.

sh: Link tests/parameters/positional8.0 to the build.

This was forgotten in r291025.

sh: Fix ""$@, which should not use the special case for "$@".

"$@" should expand to no words if there are no positional parameters, but
""$@ should always expand to at least an empty word.

Treat IFS separators in "$*" as quoted.

This makes a difference if IFS starts with *, ?, [ or a CTL* byte.

Convert bin/sh/tests to ATF

The new code uses a "test discovery mechanism" to determine
what tests are available for execution

The test shell can be specified via:

kyua test -v test_suites.FreeBSD.bin.sh.test_shell=/path/to/test/sh

sh: Correctly handle positional parameters beyond INT_MAX on 64-bit systems.

Currently, there can be no more than INT_MAX positional parameters. Make
sure to treat all higher ones as unset to avoid incorrect results and
crashes.

On 64-bit systems, our atoi() takes the low 32 bits of the strtol() and
sign-extends them.

On 32-bit systems, the call to atoi() returned INT_MAX for too high values
and there is not enough address space for so many positional parameters, so
there was no issue.

sh: Consistently treat ${01} like $1.

Leading zeroes were ignored when checking whether a positional parameter is
set, but not when expanding its value. Ignore leading zeroes in any case.

sh: Add test for ${01} and ${010} that already works.

Although it is probably unwise to use this, POSIX is clear that leading
zeroes are permitted in positional parameters (and do not indicate octal).

Such positional parameters are checked for being unset and/or null
correctly, but their value is incorrectly expanded.

sh: Initialize OPTIND=1 even if it came from the environment.

Migrate tools/regression/bin/ tests to the new layout.

This change is a proof of concept on how to easily integrate existing
tests from the tools/regression/ hierarchy into the /usr/tests/ test
suite and on how to adapt them to the new layout for src.

To achieve these goals, this change:

- Moves tests from tools/regression/bin/<tool>/ to bin/<tool>/tests/.
- Renames the previous regress.sh files to legacy_test.sh.
- Adds Makefiles to build and install the tests and all their supporting
data files into /usr/tests/bin/.
- Plugs the legacy_test test programs into the test suite using the new
TAP backend for Kyua (appearing in 0.8) so that the code of the test
programs does not have to change.
- Registers the new directories in the BSD.test.dist mtree file.

sh: Add some testcases for pasting $*/$@ directly to a literal.

This also passes on stable/8.

sh: Allow unsetting OPTIND.

Note that only assigning the decimal value 1 resets getopts, as before.

sh: Do parameter expansion on ENV before using it.

This is required by POSIX, and allows things like ENV=\$HOME/.shrc.

Note that tilde expansion is explicitly not performed.

sh: Add test for positional parameters with more than one digit.

This also passes on stable/8.

Allow one to regression test 'sh' changes without having to install
a potentially bad /bin/sh first.

sh: On startup of the shell, use PWD from the environment if it is valid.
Unset PWD if it is incorrect and no value for it can be determined.
This preserves the logical current directory across shell invocations.

Example (assuming /home is a symlink):
$ cd
$ pwd
/home/foo
$ sh
$ pwd
/home/foo

Formerly the second pwd would show the physical path (symlinks resolved).

sh: Test that bogus values of PWD are not imported from the environment.

Current versions pass this test trivially by never importing PWD, but I plan
to change sh to import PWD if it is an absolute pathname for the current
directory, possibly containing symlinks.

sh: Make sure the mail2.0 test can actually fail if $MAIL is not touched.

sh: Do not stat() $MAIL/$MAILPATH in non-interactive shells.

These may be NFS mounted, and we should not touch them unless we are going
to do something useful with the information.

Add a test for r185231.
