Remove local prototypes for main().

Make it possible to have this (basename(1)) perform basename(3) on multiple
files. The traditional behaviour, 'basename string .suffix', is preserved,
however a suffix may now also be specified via a getopt(3) option, -s, such
that if it is specified in that way, all string arguments follow. There is
also a new flag, -a, which allows a user to say "yes, please basename(3) on
all arguments". Update manual to reflect this unobtrusively.

Style improvements recommended by Bruce as a follow up to some
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

Use __FBSDID().

Include missing header files which define functions for which gcc has
builtins (e.g., exit).

Reintroduce functionality and error checks that were boneheadedly removed
in the previous commit. Pass me the pointy hat.

PR: bin/21061

Use basename(3).

Tweaks to allow compiling -Wall (mostly adding "const" to char rcsid[]).

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

This commit was generated by cvs2svn to compensate for changes in r23690,
