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.

Fix GH-1725

<itunes:explicit> accepts "explicit", "yes", "true", "clean", "no" and
"false" as valid values.

Here is the <itunes:explicit>'s description in
https://help.apple.com/itc/podcasts_connect/#/itcb54353390:

> The <itunes:explicit> tag indicates whether your podcast contains
> explicit material. You can specify the following values:
>
>   * Yes | Explicit | True. If you specify yes, explicit, or true,
>     indicating the presence of explicit content, the iTunes Store
>     displays an Explicit parental advisory graphic for your podcast.
>
>   * Clean | No | False. If you specify clean, no, or false, indicating
>     that none of your podcast episodes contain explicit language or
>     adult content, the iTunes Store displays a Clean parental
>     advisory graphic for your podcast.

I don't know whether <itunes:explicit> value is case sensitive or
insensitive. But the current implementation is case insensitive.

When you change this to true, you may need to add more tests.
