11db7fa42b Make lock(1) use PAM. This makes the -p option work again. (Well, kind of,
because the whole idea of this utility is rather broken.)

This originally come from NetBSD, and was later reworked a bit.

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.

2c9a33f557 Correct sense of crypt(3) NULL checks in init(8) and lock(1)
In r231994, an attempt was made to fix crypt(3) failure returns (NULL).
However, instead of treating crypt(3) failure as authentication failure,
some of the changes treated crypt(3) failure as authentication success.
This is wrong.

r324225 fixed this for ppp, which also inspired this review.  The other
changes in the 231994 revision were audited for correctness and look ok.

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.

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.

902d9eafbf Rework all non-contributed files that use `struct timezone'.
This structure is not part of POSIX. According to POSIX, gettimeofday()
has the following prototype:

	int gettimeofday(struct timeval *restrict tp, void *restrict tzp);

Also, POSIX states that gettimeofday() shall return 0 (as long as tzp is
not used). Remove dead error handling code. Also use NULL for a
nul-pointer instead of integer 0.

While there, change all pieces of code that only use tv_sec to use
time(3), as this provides less overhead.

54ca359425 Two fixes here:
1. If fgets fails, don't go into an infinite cpu-intensive loop.  Instead,
check to see if the terminal still exists, and sleep(1) otherwise.
2. When we check to see if the terminal still exists, make sure we're not
mislead by EINTR.  This could have been a security issue, but fortunately
the current implementation of tcgetattr doesn't EINTR.
