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.

MFC r355222, r355260:

r355222: Use strlcat().
r355260: Simplify code with strlcpy/strlcat.

MFC r343479: Fix potential buffer overflow and undefined behavior.

2019-02-09T14:21:29+00:00

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.

Move gettytab to libexec/getty/

USB device-side serial templates.

This mostly reverts to pre-r135941 behaviour.
