Add support for splitting at gigabyte boundaries. [1]

Also make both lowercase and uppercase suffix letters work
as byte-count suffixes, i.e. the following two commands are
equivalent now:

% split -b 4m foo
% split -b 4M foo

Remove undocumented historic support for treating "-" as an option
instead of a file operand; this is not compatible with POSIX.

Remove the hack that varied the first character of the output file name
if none was specified on the command line. This is not permitted by
POSIX, and no longer needed now that we have the -a option.

Support larger files (at least 64-bit offsets) by using off_t instead of

Allow "-" to be specified as an operand as well as an option.

WARNS=2 fixes, use __FBSDID, remove GCC-specific flags.

Add/fix the ability to split a file larger than 2 gigabytes.

Added $FreeBSD tag (in the way the already present sccsid is
done). I've been told the rcsid stuff may be of dubious value
so I'm curious to know if folks (still) use it.

Cosmetic in err() string.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

This fixes 'split -l NNN foo'. As it stands split will
complain about an 'illegal line count' becuase it's looking
at the wrong end pointer (ep) to detect any extra characters
after the NNN.
