Backport #3505: URI.join and Kernel::URI should accept URI objects
https://bugs.ruby-lang.org/issues/3505#change-27236

 URI.join accepts strings or URI objects, except for the first parameter which must be a string:
 
   rubydev -r uri -e 'p URI.join("http://ruby-lang.org", URI("/foo"))'
   #<URI::HTTP:0x0000010109b418 URL:http://ruby-lang.org/foo>
 
   rubydev -r uri -e 'p URI.join(URI("http://ruby-lang.org"), "/foo")'
   /usr/local/rubydev/lib/ruby/1.9.1/uri/common.rb:156:in `split': bad URI(is not URI?): http://ruby-lang.org (URI::InvalidURIError)
 
 I believe it should accept URI object as first parameter too.
 
 Also, Kernel::URI accept uri strings, but not URI objects:
 
   rubydev -r uri -e 'URI(URI("http://ruby-lang.org"))'
   /usr/local/rubydev/lib/ruby/1.9.1/uri/common.rb:156:in `split': bad URI(is not URI?): http://ruby-lang.org (URI::InvalidURIError)
 
 This corresponds to the documentation, but it is contrary to Kernel::String, Integer, Float, etc... that all accept their own type. The error message is clearly buggy (an URI object is not an invalid uri!).
 
 I believe that Kernel::URI should accept URI objects (and return them).
 
 
 The patch below corrects both and has no impact on test-all nor rubyspec.
 
 I plan to commit it unless there is objection.
 
 Yugui: should I commit it in the 1.9.2 branch too?
 
 Thanks
