Before increasing sufflen, make sure the current name plus two (including
the terminating NUL character and the to-be-added character) does not
exceed the fixed buffer length, and stop immediately if this would occur.
In worst case scenario the code would write an nul character beyond the
boundary, however it would be caught by open(2) and based on the memory
layout, we do not believe this would constitute a security vulnerability.

We've ifdef'd out the copyright strings for some time now. Go ahead and
remove the ifdefs. Plus whatever other detritis was left over from other
recent removals. These copyright strings are present in the comments and
are largely from CSRG's attempt at adding their copyright to every
binary file (which modern interpretations of the license doesn't
require).

Currently, split(1) will clobber any existing output files:
$ split file; ls
xaa xab xac xad
$ split second-file; ls
xaa xab xac xad xae xaf
This patch adds a flag "-c" (mnemonic "create, don't overwrite" or
"continue where you left off"):
$ split file; ls
xaa xab xac xad
$ split -c second-file; ls
xaa xab xac xad xae xaf xag xah xai xaj

If the input cannot be split into the number of files resulting from the
default suffix length, automatically extend the suffix length rather
than bailing out with 'too many files'.
Suffixes are extended such that the resulting files continue to sort
lexically and "cat *" would reproduce the input. For example, splitting
a 1M lines file into (default) 1000 lines per file would yield files
named 'xaa', 'xab', ..., 'xyy', 'xyz', 'xzaaa', 'xzaab', ..., 'xzanl'.
If '-a' is specified, the suffix length is not auto-extended.
This behavior matches GNU sort(1) since around version 8.16.

Something else may have set errno, breaking the post-getline() logic
that tries to detect the getline() error. This was initially noted in
a jail on a system that has HPET, in a jail that does not expose
/dev/hpet0 -- we see an earlier error in libc's vdso bits.
Fixes: 5c053aa3c5 ("split: switch to getline() [...]")
This was meant to note that both pattern and line matching were
previously restricted, but words are difficult. +line and rearrange.

Get rid of split's home-grown logic for growing the buffer; arbitrarily
breaking at LONG_MAX bytes instead of 65536 bytes gives us much more
wiggle room. Additionally, we'll actually fail out entirely if we can't
fit a line, which makes noticing this class of problem much easier.

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.
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.
