Closes https://github.com/MusicPlayerDaemon/MPD/issues/1150

A few exceptions are needed for sources which include COM header
(directly or indirectly).

This fixes lots of shadow warnings, see
https://github.com/MusicPlayerDaemon/MPD/issues/1150

Include the most specific header documented by MSDN instead.

"%lu" is portable - it works with both POSIX and Microsoft flavors.

Fixes a part of https://github.com/MusicPlayerDaemon/MPD/issues/1150

Closes https://github.com/MusicPlayerDaemon/MPD/issues/1130

Remove lots of #ifdefs.

Allows using ranges, always.  This is required to fix
https://github.com/MusicPlayerDaemon/MPD/issues/1130 without adding
more runtime conditionals.

For querying tags, the real song URI should be used, because if the
(display) URI is different, requesting it will not produce a usable
response.  This is a theoretical problem because none of the existing
playlist plugins sets the real_uri.

This requires changing the URI comparison in playlist::TagModified().

With the default value CURLAUTH_ANY, libcurl needs to probe for
authentication methods first, and only the second request will have an
Authorization header.
