This is both reasonable and a common GNUism that a lot of ported software
expects.
Universally process \r, \n, and \t into carriage return, newline, and tab
respectively. Newline still doesn't function in contexts where it can't
(e.g. BRE), but we process it anyways rather than passing
UB \n (escaped ordinary) through to the underlying regex engine.
Adding a --posix flag to disable these was considered, but sed.1 already
declares this version of sed a super-set of POSIX specification and this
behavior is the most likely expected when one attempts to use one of these
escape sequences in pattern space.
This differs from pre-r197362 behavior in that we now honor the three
arguably most common escape sequences used with sed(1) and we do so outside
of character classes, too.
Other escape sequences, like \s and \S, will come later when GNU extensions
are added to libregex; sed will likely link against libregex by default,
since the GNU extensions tend to be fairly un-intrusive.

We don't generally support the weird case of regular expresions delimited
by an opening square bracket ('[') but POSIX says that inside
bracket expressions, escaping is not possible and both '[' and '\'
represent themselves.

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

In r297602, which included a __FreeBSD_version bump to 1100105, we changed
sed 'i' and 'a' from discarding whitespaces to conform with what GNU and
sysvish sed do.
There are arguments in favor of keeping the old behavior but the new
behavior is also useful for migration purposes. It seems important to at
least consider the case of developers depending on the previous behavior,
so add a CFLAG to enable the old behaviour.

While big, the change was meant to have no effect on behavior and instead
so far we have found two regressions: one in the etcupdate tests and

This solves a reproduceable issue with very recent Mesa where REG_NOTBOL
combined with a match at the begin of the string causes our regex library
to treat the word as not begin of word.

Simplify redundant malloc'ing in sed -e.

When encountering an -e argument, sed currently mallocs a string to COPY
the optarg -- with '\n' appended. The appendage does not seem necessary --
indeed, the same call to add_compunit processing the sole command (given
without -e) passes the *argv verbatim: without making a copy, and without
appending newline.
This matches what is done in other BSDs.

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.
