27ed53c311 Remove extraneous setutxent() calls in write(1).
We already call setutxent() once during initialization.  Furthermore,
the subsequent calls occur after the process has entered capability
mode, so they fail, and attempts to fetch database entries fail as
a result.

8a16b7a18f General further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

fbbd9655e5 Renumber copyright clause 4
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.

38adbfe6b2 write(1): Capsicumify
Enter Capsicum capability sandbox pretty early in this setuid program.

Some minor modifications were needed to cache directory fds and use
relative lookups.

Rights restriction of the stdio descriptors is unfortunately pretty messy
because we need an ioctl capability not present in the current libcapsicum
helpers (FIODGNAME).

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

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

5095053036 Let wall(1) use utmpx.
Because our implementation guarantees the strings inside struct utmpx to
be null terminated, we don't need to copy everything out, which makes
the code nicer to read.

Also set WARNS to 6 and add $FreeBSD$ to keep SVN happy.

a4cc298ac9 write(1) needs to strip off the leading /dev/ from the tty name for the
current tty as returned from ttyname(3) so it can try to avoid writing to
the current tty if possible.  Previously, it did this by trimming off any
leading directory (effectively performing a basename(3) on the path
returned from ttyname(3)).  However, this chopped off too much of the path
for ttys who have directories in their name such as pts(4).  Instead, just
strip off the leading /dev/ from the path returned by ttyname(3).  This
fixes write(1) when using pts(4).
