Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Enhance uuencode with a -r option to produce raw output.

This matches with uudecode's -r option to decode raw data without initial and
final framing lines.

Also add $FreeBSD$ to a few files to keep svn happy.

Userland signed char fixes for PPC build. Problems were using a char
return for getopt() and comparing to -1, ditto with fgetc() and EOF,
and using the kg_nice value from <sys/user.h>

Make GCC 3.3 happy with rcsid[], sccs[], and copyright[].

Improve the way base64 mode is enabled based on the program name,
so that it works when the path to b64encode is used to run it.

Synch usage() and manpage for b64encode/b64decode.

Make uudecode's usage more like that of other programs.

Add b64decode & b64encode as synonyms for uudecode and uuencode -m,
respectively, for convenience when encoding or decoding base64 files.

As requested by various users.

Group the output chunks differently, to try to match BSD/OS output. Switch
to using arithmatic to determine buffer sizes to encode into.

Diane Bruce pointed out to me that BSD/OS did MIME too, so I want to match
their output, too, since my decision of 8 output groups was wholly arbitrary.

Finish converting the rest of the function declaration and prototypes
to ANSI C. Use new source ID scheme.

unbreak build:
K&R style main() makes gcc emit a warning about missing prototypes so
switch to ANSI.

remove __P

Initialize `output' in a more proper location.

Add base64 support to uuencode(1) and uudecode(1), as specified by SUSv3.

Add `-o' option to uuencode(1) to pipe the uuencoded output to an
arbitrary file, instead of just stdout.
