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.

Promoting the SIGINFO handler's log message from LOG_INFO to
LOG_NOTICE, and promoting the "Processing event ..." message from
LOG_DEBUG to LOG_INFO. Setting the logfile to LOG_NOTICE with this
change will have the same result as setting it to LOG_INFO without
this change. Setting it to LOG_INFO with this change will include
the useful "Processing event ..." messages that were previously at
LOG_DEBUG, without including useless messages like "Pushing table".
The intent of this change is that one can log "Processing event ..."
without logging "Pushing table" and related messages that are sent
for every event. The number of lines actually logged is reduced by
about 75% by making this change and setting syslog to LOG_INFO vs
setting syslog to LOG_DEBUG.

Increase the size of devd's client socket's send buffer from the
default (8k) to 128k. This prevents clients from getting
POLLHUPped during event storms. For example, during zpool creation,
the kernel emits a resource.fs.zfs.statechange event for every vdev
in the pool. A 128k buffer is large enough to hold the statechange
events for a pool with nearly 800 drives.

their socket connection any time, and devd only notices that when it gets an
error trying to write an event to the client. On a system with no device
change activity, clients could connect and disappear repeatedly without devd
noticing, leading to an ever-growing list of open socket descriptors in devd.
Now devd uses poll(2) looking for POLLHUP on all existing clients every time
a new client connection is established, and also periodically (once a minute)
to proactively find zombie clients and reap the socket descriptors. It also
now has a connection limit, configurable with a new -l <num> command line arg.
When the maximum number of connections is reached it stops accepting new
connections until some current clients drop off.

lists it reads from its configuration files on the priority field.
Because some items in the lists have the same priority, and std::sort()
is not stable, the exact order in which the items are enumerated does
not have to correspond to the order they appear in the configuration
files.
Apparently this was never noticed with libstdc++, but with libc++ it
could cause the "uhid" entry from /etc/devd/usb.conf to be used instead
of the "ums" entry (which is earlier in the file). This caused the
problem described in the PR: the USB mouse module was never loaded, and
the other actions (such as starting moused) were not executed.
To fix the problem, make devd use std:stable_sort() instead.
