Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=30367
Currently the ddx calls xf86RandR12Init()
(-> RRScreenInit()
-> RRInit()
-> RRModeInit()
-> RRCrtcInit()
-> RROutputInit())
before RRExtensionInit() is called. This causes RRErrorBase
being 0 while setting resource type error values (resource types:
RROutput, RRMode and RRCrtc). The fix moves the setting of error
values to own functions which are called in RRExtensionInit()
to get the right RRErrorBase.

(cherry picked from commit fdabcec57a)
If a client sends a big request that's too big (i.e. bigger than
maxBigRequestSize << 2 bytes), the server just disconnects it. This makes the
client receive SIGPIPE the next time it tries to send something.
The X Test Suite sends requests that are too big when the test specifies the
TOO_LONG test type. When the client receives SIGPIPE, XTS marks it as
UNRESOLVED, which counts as a failure.
Instead, remember how long the request is supposed to be and then return that
size. Dispatch() checks the length and sends BadLength to the client. Then,
whenever oci->ignoreBytes is nonzero, ignore the data read instead of trying to
process it as a request.

The drain_console() function will race with new keyboard events being added
by the hardware causing the server to lose keyboard events if the console fd
is used for input.
Only use the drain_console() when AllowEmptyInput is off which is the best
indicator we have for whether the keyboard driver will be used. This patch
will only fix the bug when hotplugging is disabled.
What we really need is a way to figure out either whether we're _not_ using
the keyboard driver (not predictable) or a way for the keyboard driver to
disable drain_console().

If the master does not have a button class, recalculating the number of
buttons required for this master dereferences a NULL pointer. Guard against
this, if the master pointer doesn't have a button class, it doesn't need to
update it's number of buttons.
Reproducible:
Two devices on the same master, device NB with axes but no buttons, device
A+B with axes and button .
If NB was the last one to send an event through the master when A+B is
removed from the server, master->button is NULL and leads to the above
NULL-pointer dereference.

The udev device_added function takes the vendor and model IDs of added
devices and converts them into an attribute that can be matched for by
an InputClass configuration using MatchUSBID. Currently, the udev
mechanism works for USB devices, but fails to work properly for
Bluetooth devices. The product IDs of the event node are actually the
IDs of the Bluetooth receiver instead of the device.
This patch reads the product ID from the PRODUCT property of the parent
of the added device. This tag is set correctly for both USB and
Bluetooth input devices. The following devices have been tested by
specifying individual InputClass sections in xorg.conf:
* Apple Keyboard (Bluetooth)
* Apple Magic Trackpad (Bluetooth)
* Apple Magic Mouse (Bluetooth)
* Microsoft Bluetooth Notebook Mouse 5000 (Bluetooth)
* Microsoft IntelliMouse Optical (USB)

A window with either dimension > 32767 can be positioned such that
coordinates > 32767 are visible on the screen. Attempts to draw to
those pixels will generate coordinates wrapped around to negative
values.
The optimized clipping macro, 'isClipped', in fbbits.h, computes
clipping in window space rather than screen space using int16 values,
and so it too has coordinates wrapped around to negative values and
hence ends up accepting the wrapped drawing coordinates.
Two possible fixes for this problem
1) Detect wrapped region coordinates and clip those to 32767.
2) Detect negative incoming coordinates and reject those
This patch takes the second approach as it is much shorter, simply
detecting when either X or Y incoming coordinate is negative, which
can never be 'within' any drawable.

A simple hack to accommodate various EDID who have detailed modes that
exceed the EDID's max pixel clock. The pixel clock is only defined in
units of 10MHz and often appears as the maximum pixel code of the
detailed modes, rounded to the nearest 10MHz. Adjusting the max_clock to
include an extra 5MHz prevents the parser from rejecting the detailed
modes.
The kernel uses the same fuzz and by including it in X we can use the
same modes in X as for the console.
Fixes:
Bug 23833 - X uses different refresh rate to that set by kernel module
https://bugs.freedesktop.org/show_bug.cgi?id=23833
In the future, we will want to try harder to keep the KMS modes but at
the same time we need to apply the restrictions as specified by the
user's configuration, and need to fill in modes for fullscreen games on
fixed-mode panels.

This is currently affecting the wacom driver, xf86PostButtonEventP() with
