Clean up the code in bin/ to reduce warnings from GCC3.

Stage 3 of 5 or so: cleanups to cp, cpdup, and date.
- Add ``const'' to appropriate variable declarations and casts.
- Convert ``quad'' types to ``long long''.
- Convert appropriate ``int'' types to ``size_t'' and ``dev_t''.
- Rename functions/variables to not conflict with globals.
- Add/remove function prototypes and #includes as appropriate.
- Split a long string constant.
- Convert K&R style declarations to ANSI style.

Do not require -i0 when -o is used.

Add cpdup to /bin (not /usr/bin), so we can start using it during boot
to simplify things like diskless booting.

Add __printflike's where possible and fix all related bugs & issues.

cpdup - Add -VV to ignore mtime

* The cpdup -V option verifies the contents of the files even if the
mtime is the same, but also (currently) recopies the file without
bothering to verify the contents if the mtime is different, even if
the contents is the same.

* Add an extension, -VV, which verifies the contents of the file and
ignores mtime entirely. A copy is only made if the ownerchip,
flags, modes, or content differs.

cpdup - Multiple additions, fixes, and one removal

* Make -x/-X (cpignore) work with remote sources.

* Add Makefile hack for _ST_FLAGS_PRESENT_ on FreeBSD.

* Suppress "Handshaked with <host>" and "Not running as root"
messages when the -q option was specified.

* Mount points are now skipped completely. (Before this,
the directories and .cpignore inside them were still read.)

* Extract scanning directories (src and dst) from DoCopy() into
a function ScanDir(), and use ScanDir() for both src and dst.

* Remove threads support. It never worked very well and is
getting in the way of new development. The intention is to
develop a more efficient pipelined algorithm in the future
which does not require threading the program.

* Use getopt(3) instead of non-standard parser, making sure
that all options still work exactly as documented in the
manual page.

* Use fnmatch(3) instead of WildCmp(), adding support for
bracket expressions (e.g. [xyz0-9]) and escaping (e.g. foo\*).
I also suspect that fnmatch() is more efficient.

* Use the same syntax for remote paths as scp(1), so local paths
that contain colons can be specified (e.g. "./foo:bar");
extract that code into its own function SplitRemote().

* Add protocol commands hc_geteuid() and hc_getgroups().
Use them to properly check permissions for various operations
that would require root privileges on the target machine.

* Bugfix: If a symlink already existed on the target but the
owner/group didn't match, cpdup missed to update it.
Added a call to hc_lchown() to fix that, if privileges allow.

* Bugfix: The dispatch[] array wasn't initialized, so the slave
crashed upon an unknown command instead of calling rc_badop().

* Bump protocol version to 3 in order to be able to maintain
backwards compatibility with older clients.

* Bump utility version to 1.16.

* Make the source compile with WARNS=6.
It still doesn't pass -ansi -pedantic, though. :-)

* Document -j0, -k and -K in usage message (misc.c).

* Update the manual page, fix mdoc markup and various details.

* Add "ssh security tips" section to the BACKUPS text file.
