Implementation of remote file API for correct FilePath
work with RemoteLinux.
Added tests for this functionality
Run ssh shell in separate thread.
The linux device instance keeps its own thread for running
SshRemoteProcess. In this way all calls to filepath
interface of linux device coming from different threads
are executed in one thread (SshRemoteProcess is reentrant,
but not thread safe). The redirection to the device thread
is done by invoking SshRemoteProcess' methods through
BlockingQueuedConnection.
