ftp backend: Dynamically resolving resource path with URL prefix

The code used to retrieve FTP resource with the path of QUrl as an
absolute URL starting from the root directory. It is not always working
with a relative URL because the root directory and working directory may
be different. Depending on the implementation of FTP server, the
reference directory of a relative URL could be either the root directory
or the working directory.

To resolve it, a new state “ResolvingPath” is added to resolve resource
paths before retrieving. For both GET and PUT operations supported by
QNetworkAccessFtpBackendFactory, the resource will be retrieved via its
URL path. Depending on the prefix of the URL path, the path of working
directory is prepended to the resource path as an absolute path starting
with the working directory.

If a URL path starts with “//” or “/%2F” user-input prefix, the resource
will be retrieved by an absolute path starting with the root
directory. If a path starts with /~/ or the working directory prefix,
its resource will be retrieved from the working directory.
