Review request for kdeconnect.


Changes
-------

Add support for payloads of unknown size.


Repository: kdeconnect-kde


Description (updated)
-------

When sending a payload,  a `===BEGIN PAYLOAD===` and `===END PAYLOAD===` markers are sent with the payload. On the receiving end, the data between these two markers is captured, and the size is checked. If the size doesn't match, then the current implementation just returns a package without a payload (which might be good or bad). If the size is unknown, then the data is assumed to have been transmitted correctly.

In addition, `core/filetransferjob.cpp` was edited to listen to the `aboutToClose()` signal instead of the `disconnected()` signal, which is guaranteed to exist on all implementations of `QIODevice`. I'm not sure of the side effects for the LAN device link.
