ipv6 adjustments

                               History of Changes

- Added simple IPv6 detection in the configure script and made the version

  string add 'ipv6' to the enable section in that case. ENABLE_IPV6 will be

  set if curl is compiled with IPv6 support enabled.

- Added a parser for IPv6-style specified IP-addresses in a URL. Thus, when

  IPv6 gets enabled soon, we can use URLs like '[0::1]:80'...

- Made the URL globbing in the client possible to fail silently if there's an

  error in the globbing. It makes it almost intuitive, so when you don't

  follow the syntax rules, globbing is simply switched off the the raw string

  is used instead.

  I still think we'll get problems with IPv6-style IP-addresses when we *want*

  globbing on parts of the URL as the initial part of the URL will for sure

  seriously confuse the globber.

- Björn Stenberg supplied a progress meter patch that makes it look better even

  during slow starts. Previously it made some silly assumptions...
