* lib/net/http.rb: Net::HTTP now automatically detects and uses

  proxies from the environment.  A proxy may also be specified as
  before.

  Net::HTTP::Proxy still creates anonymous classes, but these classes
  are only used to store configuration information.  When an HTTP
  instance is created the configuration is now copied.

  Additionally, Net::HTTP::ProxyDelta is no longer used by Net::HTTP

  [Feature #6546]
* lib/open-uri.rb:  Moved URI::Generic#find_proxy to uri/generic.
* lib/uri/generic.rb:  Imported find_proxy from open-uri.
* test/open-uri/test_open-uri.rb:  Moved proxy-discovery tests to URI.
* test/uri/test_generic.rb:  Imported proxy-discovery tests from
  open-uri.
* test/net/http/test_http.rb:  Added tests for proxy behavior.
