Revert $FreeBSD$ to $Id$

Some bug-fixes, clean-ups, and one new feature:

- Fix the bug with URIs of the form ftp://host/filename.
- Fix some more string-termination bugs in util.c.
- Use safe_malloc() rather than testing the return value of
regular malloc() in 15 places.
- Implement HTTP authentication, for both servers and proxies.
Currently only ``basic'' authentication is supported; This Is A Bug
(but less of one tjhan nmot supporting any authentication).

I think there is only one more feature which is required for full
HTTP/1.1 support, which is Transfer-Encoding: chunked; this should
not be toohard, but it isn't very important, either.

Some fixes for HTTP:

1) Implement redirects (or try to, at least).
2) Implement automatic retry after 503 errors when Retry-After is given.
3) Implement a -a flag to enable both of these behaviors.
4) Recognize Transfer-Encoding headers and emit a warning that the file
is likely to be damaged.
5) Bug fix: only write the amount of data we read.
6) Actually document some of these.
7) Fix the usage message to display flags in semi-alphabetical order.

Here is my long-threatened revamping of fetch. Jean-Marc probably won't
recognize it any more. This makes the following significant changes:

- The main body of the program doesn't know a thing about URIs,
HTTP, or FTP. This makes it possible to easily plug in other
protocols. (The next revision will probably be able to dynamically
add new recognizers.)

- There are no longer arbitrary timeouts for the protocols. If you want
to set one for yourself, use the environment variables.

- FTP proxies are now supported (if I implemented it right).

- The HTTP implementation is much more complete, and can now do restarts,
preserve modtimes, and mrun in mirror mode. It's not yet up to 1.1,
but it's getting there.

- Transaction TCP is now used for sending HTTP requests. The HTTP/1.1 syntax
for requesting that the connection be closed after one request is
implemented.

In all of this, I have doubtless broken somebody. Please test it and tell me
about the bugs.

Sort cross references.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

add missing comma(s) in .Xr macros

Attempt to untangle the timeout code a bit, also make the default ftp
and http timeouts the same, since when using a http proxy to do ftp
transfers, the http timeout was being used for what is coming in via
ftp.

Allow proper ftp verbosity with a new -v flag.

Use the .Fx macro where appropriate.

1. Understand file:/path style URLs.
2. Add a -l flag for symlinking to rather than copying file:/path style URLs.
3. Add a -T flag for setting the timeout interval (overrides FTP_TIMEOUT if set)
