split(1): add '-c' to continue creating files

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

split(1): auto-extend suffix length if required

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.

split: add word order fix

This was meant to note that both pattern and line matching were
previously restricted, but words are difficult. +line and rearrange.

split: switch to getline() for line/pattern matching

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.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

When "-b" is specified, one could easily create "smaller" files
that are much larger than expected (given the default size).
Change "smaller files" to "split files" which is more in line
with what "-b" actually does.
