r343362:
Add [initial] functional tests for sendfile(2) as lib/libc/sys/sendfile
These testcases exercise a number of functional requirements for sendfile(2).
The testcases use IPv4 and IPv6 domain sockets with TCP, and were confirmed
functional on UFS and ZFS. UDP address family sockets cannot be used per the
sendfile(2) contract, thus using UDP sockets is outside the scope of
testing the syscall in positive cases. As seen in
`:s_negative_udp_socket_test`, UDP is used to test the sendfile(2) contract
to ensure that EINVAL is returned by sendfile(2).
The testcases added explicitly avoid testing out `SF_SYNC` due to the
complexity of verifying that support. However, this is a good next logical
item to verify.
The `hdtr_positive*` testcases work to a certain degree (the header
testcases pass), but the trailer testcases do not work (it is an expected
failure). In particular, the value received by the mock server doesn't match
the expected value, and instead looks something like the following (using
python array notation):
`trailer[:]message[1:]`
instead of:
`message[:]trailer[:]`
This makes me think there's a buffer overrun issue or problem with the
offset somewhere in the sendfile(2) system call, but I need to do some
other testing first to verify that the code is indeed sane, and my
assumptions/code isn't buggy.
The `sbytes_negative` testcases that check `sbytes` being set to an
invalid value resulting in `EFAULT` fails today as the other change
(which checks `copyout(9)`) has not been committed [1]. Thus, it
should remain an expected failure (see bug 232210 for more details
on this item).
Next steps for testing sendfile(2):
1. Fix the header/trailer testcases so that they pass.
2. Setup if_tap interface and test with it, instead of using "localhost", per
@asomers's suggestion.
3. Handle short recv(2)'s in `server_cat(..)`.
4. Add `SF_SYNC` support.
5. Add some more negative tests outside the scope of the functional contract.

r343365:
Unbreak the gcc build with sendfile_test after r343362
gcc 8.x is more pedantic than clang 7.x with format strings and the tests
passed `void*` variables while supplying `%s` (which is technically
incorrect).
Make the affected `void*` variables use `char*` storage instead to address
this issue, as the compiler will upcast the values to `char*`.

Unbreak the build on architectures where size_t isn't synonymous with uintmax_t
I should have used `%zu` instead of `%ju` with `size_t` types.

Fix up r343367
I should have only changed the format qualifier with the `size_t` value,
`length`, not the other [`off_t`] value, `dest_file_size`.

Fix reporting errors with `gai_strerror(..)`
The return value (`err`) should be checked; not the `errno` value.

r343751:
Avoid the DNS lookup for "localhost"
ci.FreeBSD.org does not have access to a DNS resolver/network (unlike my test
VM), so in order for the test to pass on the host, it needs to avoid the DNS
lookup by using the numeric host address representation.

r344310:
Make `server_cat(..)` handle short receives
In short, the prior code was far too simplistic when it came to calling recv(2)
and failed intermittently (or in the case of Jenkins, deterministically).
Handle short recv(2)s by checking the return code and incrementing the window
into the buffer by the number of received bytes. If the number of received
bytes <= 0, then bail out of the loop, and test the total number of received
bytes vs the expected number of bytes sent for equality, and base whether or
not the test passes/fails on that fact.
Remove the expected failure, now that the hdtr testcases deterministically pass
on my host after this change [1].

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.

Add reachover Makefiles for contrib/netbsd-tests/lib/libc; this adds approximately
500 new testcases
Various TODOs have been sprinkled around the Makefiles for items that even need
to be ported (missing features), testcases have issues with building/linking, or
issues at runtime.
A variant of this code has been tested extensively on amd64 and i386
10-STABLE/11-CURRENT for several months without issue. It builds on other
architectures, but the code will remain off until I have prove it works on
virtual hardware or real hardware on other architectures
