7cc42f6d25 Do a sweep and remove most WARNS=6 settings
Repeating the default WARNS here makes it slightly more difficult to
experiment with default WARNS changes, e.g. if we did something absolutely
bananas and introduced a WARNS=7 and wanted to try lifting the default to
that.

Drop most of them; there is one in the blake2 kernel module, but I suspect
it should be dropped -- the default WARNS in the rest of the build doesn't
currently apply to kernel modules, and I haven't put too much thought into
whether it makes sense to make it so.

49d941eee0 getty appears to date from 3rd edition research unix. That's the oldest man page
on TUHS and its 'unix 1972' restoration effort has assembler sources that look
like simpler version of what's in the 5th edition.

71bc4af6ed Fix potential buffer overflow and undefined behavior.
The buffer allocated in read_chat() could be 1 element too short, if the
chatstr parameter passed in is 1 or 3 charachters long (e.g. "a" or "a b").
The allocation of the pointer array does not account for the terminating
NULL pointer in that case.

Overlapping source and destination strings are undefined in strcpy().
Instead of moving a string to the left by one character just increment the
char pointer before it is assigned to the results array.

170430d505 Prevent getty(8) from looping indefinitely if the device node doesn't

USB device-side serial templates.

This mostly reverts to pre-r135941 behaviour.

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.

ff48be37b5 Add a new getty/gettytab capability to generate an initial message dynamically.
This modification adds a new gettytab(5) option (iM) to specify a
program to run that will generate the initial (banner) message that is
displayed before the login prompt. Such a capability is useful when
dynamic information is needed in the banner message that cannot be
supplied by the set of % substitution sequences available in the "im"
option.

37b5835028 Impelemnt ttys onifexists in init.
Implement a new init(8) option in /etc/ttys. If this option is present
on the entry in /etc/ttys, the entry will be active if and only if it
exists.  If the name starts with a '/', it will be considered an
absolute path. If not, it will be a path relative to /dev.

This allows one to turn off video console getty that aren't present
(while running a getty on them even when they aren't the system
console). Likewise with serial ports.

It differs from onifconsole in only requiring the device exist rather
than it be listed as one of the system consoles.

f73ff060d2 Try to fix the old "he capability is stupid" bug in gettytab(5)/getty(8)
There is one capability explicitly documented in gettytab(5) as stupid: he.
And it is indeed.  It was meant to facilitate system hostname modification,
but is hardly usable in practice because it allows very limited editing
(e.g., it depends on a particular hostname length, making it non-generic).

Replace it with simple implementation that treats ``he'' as POSIX extended
regular expression which is matched against the hostname.  If there are no
parenthesized subexpressions in the pattern, entire matched string is used
as the final hostname.  Otherwise, use the first matched subexpression.
If the pattern does not match, the original hostname is not modified.

Using regex(3) gives more freedom, does not complicate the code very much,
and makes a lot more sense, in turn making ``he'' less stupid and actually
useful (e.g., it is now possible to obtain node or domain names from the
original hostname string, without knowing it in advance).
