Vlad Zahorodnii 152d7250a5 Pass a dedicated fd to each keyboard for the xkb keymap 
Summary:
To better isolate the clients from each other eachh KeyboardInterface
creates it's own dedicated temporary file and sends the fd for this
temporary file to the client. This means the memory for the keymap is no
longer shared between all clients, every client has an own copy.

To support this the existing API to set the keymap is deprecated and
replaced by a new method setKeymapData which takes the content of the
keymap as a byte array. The now deprecated method which takes a file
descriptor is changed to use the new setKeymapData method. For that it
reads the content of the file.

The implementation in KeyboardInterface to create the file descriptor is
based on the implementation of KWin. As I implemented the change in KWin
(see 3b4c508ee3) it is not a problem from
GPL vs LGPL perspective.

The change includes test cases to verify that the content of the keymap
is properly passed to the client and that the memory is no longer shared.
