correctly check for pageid in tpl_include_page

@scrutinizer-notifier noticed that the $pageid might be false when
page_findnearest looks for it.

Make cleaning optional in mediaFN, keep as default

As in wikiFN cleaning the id should be optional, but still the default, in mediaFN as well.

when a form was submitted with an empty input, that data should still

use LF instead of CRLF as discussed in #1101

Until we did some more research on compatibility we should stick with
what works, even when the RFC says otherwise.

Should we decide to change line endings to RFC conform CRLF, it should
be done on the whole body, not the signature only.

URI scheme is only relevant for TLS if not proxy connection #1526

This should fix the test problems errors in #1527. When requesting a
HTTPS URI from a HTTP only proxy, the initial connection is *not* TLS
secured. The URI scheme is only relevant when directly connecting.

This also changes the (wrong) assumption that everything on port 443 is
always TLS secured. Only the URI scheme should decide that.

The header() method of PHP is vulnerable to HTTP Response Splitting
attacks.

This change makes sure the URL passed to send_redirect (and thus to
header()) does not contain any control characters that would be needed
to execute such an attack.

Cleaning input is recommended anyway.
