 Rationale

 All the applications embedding Tor binaries (TorChat, APAF Framework,
 GlobaLeaks) that use Tor Hidden Service have to setup a Tor Hidden
 Service.

 Currently Tor Hidden Services are created automatically by Tor into the
 Tor HiddenServiceDir configuration directive, by creating two files:
  - private key
  - file containing the hostname

 This method of activation/configuration of Tor HS data is not particularly
 application integration friendly because:
   - It require Filesystem operations just to know the hostname of a TorHS
   - Make difficult to protect the Tor HS Private Key (Use need filesystem
 encryption rather than just application-level encryption to preserve this
 private data)

 This feature enhancement propose to let the creation of a Tor Hidden
 Service by loading the required files and configuration via Tor Control
 Protocol.

 That way Python application via TorCtl/TxTorCon would be able to create
 and setup TorHS by loading the Private Key dynamically on-boot.

 The applications that way would be able to store in an application
 database all the information to write-from-scratch Tor configuration and
 Tor HS data.

 The application database maybe encrypted, to protect the Tor HS private
 key and prevent Tor HS hijacking in case of computer seizure.
