Input: usbtouchscreen - fix buffer overflow, make more egalax work
Fix a buffer overflow in mutli-packet handling code. The overflow can
only happen with eGalax devices and is even there very unlikely (only
non-report packet are affected any only when truncated after the first
byte).
Also changes the mutli-packet handling code not to drop unknown packets,
but rather just drop one byte. This allows synchronizing on report packets
in the data stream. It's required for some egalax devices to work at all.
Also remove the pointless 'flags' member of the device struct and set the
version number to 0.6, plus some minor cleanups.

Input: mousedev - handle mice that use absolute coordinates
Devices like the HP Integrated Remote Console Virtual Mouse, which are
standard equipment on all Proliant and Integrity servers, produce
absolute coordinates instead of relative coordinates. This is done to
synchronize the position of the mouse cursor on the client desktop
with the mouse cursor position on the server. Mousedev is not
designed to pass those absolute events directly to X, but it can
translate them into relative movements. It currently does this for
tablet like devices and touchpads. This patch merely tells it to also
include a device with ABS_X, ABS_Y, and mouse buttons in its list of
devices to process input for.
This patch enables the mouse pointer to move when using the remote
console.

We need struct pernet_operations to last until we call unregister_pernet_subsys.

So marking struct pernet_operations is a disaster for modules in two ways.
- We discard it before we call the exit method it points to.
- Because I keep struct pernet_operations on a linked list discarding
it for compiled in code removes elements in the middle of a linked
list and does horrible things for linked insert.
