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.

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.

- Limit rights on stdio before opening input files. Otherwise, open()
may return one of the standard descriptors and we end up limiting
rights such that we cannot read from one of the input files.
- Use caph_limit_stdio(), which suppresses EBADF, to ensure that
we don't emit an error if one of the stdio streams is closed.
- Don't bother further limiting rights on stdin when stdin isn't going
to be used. Doing so correctly requires checking for a number of
edge cases, and it doesn't provide any significant benefit.

These match GNU cmp(1) for compatibility where applicable.
Future work might implement the -i option from GNU cmp(1) to express skip
either in terms of both files or of the form "SKIP1:SKIP2" rather than
specifying them as additional arguments to cmp(1).

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.

Special thanks to Wind River for providing access to "The Duke of

starting point.

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

This is not actually documented or even implied in style(9). Make the change

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.

WITH_META_MODE we get auto objdir creation, the ability to

Still need to add real targets under targets/ to build packages.

comparing regular files. Add a SIGSEGV handler to make its
behavior less surprising when a read error occurs. The handler
does not attempt to distinguish errors from file truncation, but
anyone actively modifying a file while trying to compare it
shouldn't even expect something sane to happen.
