- Initialize the disk device fd field in connection_new().
- Close the disk device after handing the connection over
to a child worker.
- Avoid re-opening a disk device for each connection from
the same client, avoiding an fd leak.

various: general adoption of SPDX licensing ID tags.

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.

Add pidfile support to ggated(8)

The tests will manipulate the system daemon today, which can cause undesired
service interruption when the tests are run.

This change allows the geom_gate tests to be run with an arbitrary ggated(8)
daemon / geom_gate(4) device pairing.

Other changes:
- Sort #includes
- Use a more common idiom for parsing options with getopt(3)

If ggated's exports_find() fails, the connection is removed before
(trying to) report the problem to the client.

sendfail() is called with an already closed socket and thus it
fails to inform the client about the problem.

Fix this by calling sendfail() before connection_remove().

Fix warnings found by -Wmising-variable-declarations.

This self-written compiler warning, which is hopefully going to be
committed into LLVM sources soon, warns about potentially missing
`static' keywords, similar to -Wmissing-prototypes.

- bin/pax: Move external declaration of chdname and s_mask into extern.h.
- bin/setfacl: Move setfacl.c-specific stuff out of setfacl.h.
- sbin/mount_fusefs: Remove char *progname; use getprogname().
