It was pointed out that a couple of the "memory leak" CIDs that I
fixed were arguably Coverity errors rather than errors in the
newsyslog code and the cure was worse than the disease. Revert both
changes. The first change, which included fixes for other Coverity
errors, will be re-worked to omit the troublesome changes and then
re-committed with the remaining fixes.

The result of a strdup() was stored in a global variable and not freed
before program exit. This is a follow-up to r343906. That change
attempted to plug these resource leaks but managed to miss a code path
on which the leak still occurs. Plug the leak on that path, too.

The new default config will only include files from the following
directories which end with '.conf' and do not beginning with a '.'
character:
- /etc/newsyslog.conf.d/
- /usr/local/etc/newsyslog.conf.d/
This matches the syslog.conf(5) functionality, and also prevents '.sample' or
'.pkgnew' files being included. This is important for ports which install files
in /usr/local/etc/newsyslog.conf.d/ and also for pkgbase.

- Simplify the compression args arrays at the expense of a __DECONST
when calling execv().
- Rewrite do_zipwork. The COMPRESS_* macros can directly index the
compress_types array, so the outer loop is not needed. Convert

The zstd invocation constructed by newsyslog contains one more parameter
than invocations for the other supported compression utilities. However,
the maximum number of arguments was hard-coded, leading to an
out-of-bounds array access when using zstd compression.
Reuse of the index variable in two nested loops resulted in only the first
argument in the list being used (fine for gzip, not fine for zstd). Also
add tests for xz and zstd, and fix the COMPRESS_SUFFIX_MAXLEN macro.

When building the command to execute for compression, newsyslog was modifying
the generic arguments array instead of its own copy.
Meaning on the second file to compress with the same arguments, the command line
was not the one expected.
Fix it by creating one copy of the arguments per execution and modifying that
copy.
While here, print the command line executed in verbose mode.
Reported by: many
have a semantic different than the traditional gzip(1)
This is done to allow to use zstd(1) as a compression tool without
having to patch it to change its default behavior.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
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.
No functional change intended.
This modification adds the capability to newsyslog to write the
rotation message in a format that is compliant with RFC5424. This
capability is enabled on a per-log file basis through a new value
("T") in the flags field in newsyslog.conf. This is useful on systems
that use the RFC5424 format for log files so that the rotation message
format matches that of the other log messages. There has been recent
mention of adding an RFC5424 compliant mode to syslogd and at least
one alternative system log daemon (rsyslogd) that already has the
capability to use that format.

This makes newsyslog use zstandard to compress log files.
Given Z is already taken for gzip and zstandard compression level stands in
between gzip and xz (which has the X flag) chosing Y sounds ok :)
It turns out that we had a couple of more calls to dirname()/basename()
in newsyslog(8) that assume the input isn't clobbered. This is bad,
because it apparently breaks log rotation now that the new dirname()
implementation has been merged.
Fix this by first copying the input and then calling
dirname()/basename(). While there, improve the naming of variables in
this function a bit.

Pull copies of the input pathname string before calling basename() and
dirname() to make this comply to POSIX. Free these copies at the end of
this function. While there, remove the duplication of the 's' ->
'logfname' string. There is no need for this.
After going through the signal work list, during which do_sigwork()
is called and essentially does nothing because -s and -R were
specified on the command line, newsyslog will sleep for 10 seconds
as the (verbose) code says: "Pause 10 seconds to allow daemon(s)
to close log file(s)".
However, the man page verbiage for -R (and -s) seems quite clear
that this sleep() is unnecessary because the daemon was expected
to have already closed the log file before calling newsyslog.

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.
