Fixed static linkage.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Reimplementation of world/kernel build options. For details, see:

NOCRYPT -> NO_CRYPT

Join the 21st century: Cryptography is no longer an optional component
of releases. The -DNOCRYPT build option still exists for anyone who
really wants to build non-cryptographic binaries, but the "crypto"
release distribution is now part of "base", and anyone installing from a
release will get cryptographic binaries.

Discussed on: freebsd-current, in late April 2004

Make sure the crypto versions of libfetch and fetch(1) appear in
the "crypto" distribution.

Retire the useless NOSECURE knob.

Mark fetch(1) as c99- and WARNS6-clean.

Clarify my feelings towards fetch / libfetch.

fetch(1) is WARNS-5 clean (tested on i386 and Alpha)

Reorder LDADD to fix static linking.

libfetch now depends on libcrypto and libssl.

Figures they had to call it NOCRYPT instead of NOCRYPTO.

During buildworld, "regular" libraries are built before crypto stuff, so
libfetch can't depend on lib{crypto,ssl}. Move the dependency to fetch
until we can figure out how to fix this.

Remove leaf node WARNS?=2 (that mainly I added). This should
help the GCC3 transition and CURRENT in general.

WARNS cleanup + remove an unused macro and an unused function argument.

New libfetch-based fetch.

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.

Add -Wall to CFLAGS
