80445b7a3f cmp: fix -s (silent) when used with skip offsets
-s causes cmp to print nothing for differing files, for use when only
the exit status is of interest.

-z compares the file size first, for regular files, and fails the
comparison early if they do not match.

Prior to this change -s implied -z as an optimization, but this is not
valid when file offsets are specified.  Now, enable the -z optimization
for -s only if both skip arguments are not provided / 0.

Note that using -z with differing skip values will currently always
fail.  We may want to compare size1 - skip1 with size2 - skip2 instaead,
and in any case the man page should be clarified.

2528b7e2cb Fix handling of rights on stdio streams, take two.
Split the rights-limiting code into two cases: if one of the input
files isn't a regular file, use caph_limit_stream(3) instead of
open-coding the same logic; if both input files are regular files,
and the initial attempts to map them succeed, we limit the rights on
those files to CAP_MMAP_R.

Add a regression test for PR 234885.

109b5c109c Fix cmp(1) tests for "special" mode.
Test failures don't seem to propagate up if atf_check is run in
a pipeline.  Thus, the tests continued to pass despite the bug reverted
in r343245.

430f7286a5 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.
