0a45fcc700 KASM-1871 Add smooth scrolling 
Previously all scrolling relied on "clicking" the up/down or left/right scroll buttons
which made it unprecise and to always scroll at the same speed.

Now we pass the scroll delta directly to the xorg input driver so the scroll is more responsinve and adaptive.

25b8e64adb Add support for notifying clients about pointer movements 
This change adds support for the VMware Mouse Position
pseudo-encoding[1], which is used to notify VNC clients when X11 clients
call `XWarpPointer()`[2]. This function is called by SDL (and other
similar libraries)  when they detect that the server does not support
native relative motion, like some RFB clients.

With this, RFB clients can choose to adjust the local cursor position
under certain circumstances to match what the server has set. For
instance, if pointer lock has been enabled on the client's machine and
the cursor is not being drawn locally, the local position of the cursor
is irrelevant, so the RFB client can use what the server sends as the
canonical absolute position of the cursor. This ultimately enables the
possibility of games (especially FPS games) to behave how users expect
(if the clients implement the corresponding change).

Part of: #619

80a637c793 Fix division by zero exception in SSecurityPlain. 
If using SSecurityPlain and the user specifies an empty username
and password, it will invoke InStream::checkNoWait(0) which will
cause a division by zero when calculating the number of available
items.

Enhance InStream::check() to behave properly when asked for
zero items, or zero sized items.

Add comments to InStream::check(), InStream::checkNoWait(),
and InStream::readBytes() to document expected behaviour
when requested to check or read zero items, or an item with
zero size.

Created a new subclass of Exception called GAIException() that will

handle it. GAIException() will make use of gai_strerror() to map the
error code to text. On Windows, gai_strerrorW() must be used if the text
is encoded with UTF-8.
