[FTP] introduce GVfsFtpTask

split out the old FtpConnection struct into a separate GVfsFtpTask
structure that acts as a one-stop solution to vfuncs. It keeps track of
all important structures:
- the backend
- the current job
- the potential connection to the server
- the error state
during the lifetime of a backend vfunc and supplies convenience
functions to ease implementing these vfuncs. The API of gvfsftptask.h is
documented.
