If uplevel keyword is given, the warning message is prepended with caller file and line information and the string "warning: ". The use of the uplevel keyword makes Kernel#warn format output similar to how rb_warn formats output. This patch modifies net/ftp and net/imap to use Kernel#warn instead of $stderr.puts or $stderr.printf, since they are used for printing warnings. This makes lib/cgi/core and tempfile use $stderr.puts instead of warn for debug logging, since they are used for debug printing and not for warning. This does not modify bundler, rubygems, or rdoc, as those are maintained outside of ruby and probably wish to remain backwards compatible with older ruby versions. rb_warn_m code is originally from nobu, but I've changed it so that it only includes the path and lineno from uplevel (not the method), and also prepends the string "warning: ", to make it more similar to rb_warn.
