Allow specifying a protocol in the host field when mounting another
ownCloud instance. Note that this was already possible with the WebDAV
config but this bug made it inconsistent.
We do not want to follow redirects to other protocols since they might allow an adversary to bypass network restrictions. (i.e. a redirect to ftp:// might be used to access files of a FTP server which might be in a secure zone and not be reachable from the net but from the ownCloud server)
Get final redirect manually using get_headers()
Migrate to HTTPHelper class and add unit tests
As constants not defined within a class cannot be automatically found by the
autoloader moving those constants into a class makes them accessible to
code which uses them.
