Issue #1082
dde_linux: Remove bogus line from XHCI patch

This was a left over from the 'vi' editor
Use signals for delivering input events

This patch changes both the Input::Session interface and the skeleton
for the server-side implementation of this interface
('input/component.h').

The Input::Session interface offers a new 'sigh' function, which can be
called be the client to register a signal handler. The signal handler
gets notified on the arrival of new input. This alleviates the need to
poll for input events at the client side.

The server-side skeleton for implementing input services underwent a
redesign to make it more modular and robust. I.e., there are no
global functions needed at the server side and the event-queue
enable/disable mechanism is implemented at a central place (in the root
component) rather than inside each driver.

Fixes #46
dde_linux: implement memory barriers in USB driver

This patch implements the memory barrier macros in the USB driver for ARMv7
and x86.

Fixes #1159.
ram_blk: change blocksize output to decimal

Reading 200 instead of 512 is confusing.

Fixes #1142.
ram_blk: remove superfluous block_number check

block_number is Block::sector_t (uint64_t), which never can by less
than 0.

Fixes #1142.
Qt5: use the Genode main thread

Now that it is possible to resize the stack of the Genode main thread, it
is not necessary anymore to create a new Genode thread as Qt main thread.

Fixes #1134.
Qt5: constrain the window buffer refresh area

With this patch, the information about the changed window area is taken
into account when refreshing the Nitpicker buffer.

Fixes #1132.
Generic resource monitor (WiP)
os: Construct invalid 'Rect' by default
os: Utility for tracking dirty rectangles
nitpicker: Perform redraw asynchronously

This patch changes nitpicker's way of redrawing. Originally, redraw
operations were triggered immediately by the RPC functions invoked by
clients. In the presence of clients that invoked a large number of those
functions, the server could become overloaded with processing redraw
operations. The new version performs redraw operations out of band with
the RPC functions. Similar to the design of the DOpE GUI server, redraw
operations are processed periodically. The RPC functions merely modify
meta data and track the dirty areas that need to be updated.
Consequently, nitpicker's RPC functions become light-weight operations.

As a nice collateral effect of this patch, nitpicker's internal
structure could be simplified because the drawing backend is no longer
needed by the code that dispatches the RPC interface.
