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.
Apply authenticated user context after update of wtmp(5) at start of session,
so that ftpd process is not killed by kernel with SIGXFSZ when user has
"filesize" limit lower than size of system wtmp file. Same applies
to session finalization: revert to super-user context before update of wtmp.
If ftpd hits limit while writing a file at user request,
do not get killed with SIGXFSZ instantly but apparently ignore the signal,
process error and report it to the user, and continue with the session.

The locally declared enum of blacklistd actions needs to be
hidden when the soon to be committed changes to libblacklist
are brought into the tree. Fix the type of the "msg" parameter
to match the library.
There should be no functional changes.

The ftp daemon dups the control socket to stdin and uses that fd
throughout the code. Clarify this usage slightly by changing from
explicit use of "0" for the fd to a variable, to make it clear what
the zero represents in the non-blacklist code. Make the
blacklist_notify routine use STDIN_FILENO so as to have less of a
"magic number" feel to the code.

These are no longer needed after the recent 'beforebuild: depend' changes

Off by default, build behaves normally.

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

the caller. Currently, checkuser() does not differentiate between the
failure to open the file and the absence of a user in the file. Check
to see if there was an error opening the file. If there are any errors,
terminate the connection. Currently, the only exception to this rule
is ENOENT, since there is nothing that says the /etc/ftpuser
and /etc/ftpchroot has to exist.

This makes it a little easier to figure out which application was
responsible for this log entry. Ideally we should add an ut_process or
something similar.

Also perform a small cleanup to ftpd_logwtmp(). Just use a NULL
parameter for the username to indicate a logout, instead of an empty
string.

Unfortunately I have to partially wreck its functionality, though. ftpd
used to keep a file descriptor to the wtmp, which allowed it to work
from within a chroot. The current utmpx implementation doesn't offer a
way to do this. Maybe we can address this in the future, if it turns out
to be a real issue.
