This call is required for external drivers (specifically NVIDIA) that do
not share the xfree86 infrastructure to update the desktop dimensions.
Without it, the driver would update the ScreenRecs but not update the total
dimensions the input code relies on for transformation.
This call is a thin wrapper around the already-existing internal call and
should be backported to all stable series servers, with the minor ABI bump.

Some compilers have difficulty with the previous implementation which
relies on undefined behavior according to the C standard. Using
offsetof() from <stddef.h> (which most likely just uses
__builtin_offsetof on modern compilers) allows us to accomplish this
without ambiguity.
This fix also requires support for typeof(). If your compiler does not
support typeof(), then the old implementation will be used. If you see
failures in test/list, please try a more modern compiler.
v2: Added fallback if typeof() is not present.

When fbBresSolid draws a line, it can happen that after the last
pixel, the Bresenham error term overflows, and fbBresSolid paints
another pixel before adjusting the error term.
However, if this happens on the last pixel (len=0), this extra pixel
might overshoot the boundary, and, in rare cases, lead to a segfault.
Fix this issue by adjusting for the Bresenham error term before
drawing the main pixel, not after.

(cherry picked from commit 863d528a9f)
If a device has smooth scrolling axes, but submits scroll button events, we
convert those to motion events and update the valuators. For legacy button
events, the valuator mask is likely unset though, causing
add_to_scroll_valuator() to return early, leaving us with an empty mask.
That again skipped the rest of the code and no events were generated.
Fix it by making sure that the scroll valuator in the mask is at least
initialized to 0.

That commit adds two hunks, and I _think_ they're backwards. It adds
code to modify bracket_greater on NegativeTransition triggers, and
bracket_less on PositiveTransition triggers. That breaks symmetry with

simplified further.

Let's say - purely for the sake of argument, mind you - that you had a
server GPU with anemic memory bandwidth, and you walked up to it and
plugged in a monitor that was 1920x1080 because that's what happened to
be on the crash cart. Say the memory bandwidth is such that anything
larger than 1280x1024 gets filtered away. Now you're in trouble,
because the established timings section includes a 720x400 mode because
that's what DOS 80x25 is, and that happens to just about match the
physical aspect ratio.
Instead let's reuse the logic from the existing aspect-match path: pick
the larger mode of either the physical aspect ratio or 4:3.

LoaderSymbol calls dlsym with RTLD_DEFAULT pseudo handle making it search in
every loaded library. In addition glibc adds NODELETE flag to the library
containing the symbol.
It's used in doLoadModule to locate <modulename>ModuleData symbol, the
module's library gets the flag and is kept in memory even after it is
unloaded.
This patch adds LoaderSymbolFromModule function that looks for symbol only in
library specified by handle. That way the NODELETE flag isn't added.
This glibc behavior doesn't seem to be documented, but even if other
implementations differ, there is no reason to search ModuleData symbol outside
the module's library.

Ricardo Salveti <ricardo.salveti@linaro.org> found one place where the
randr code could use the randr screen private data without checking
for null first. This happens when the X server is running with
multiple screens, some of which are randr enabled and some of which
are not. Applications making protocol requests to the non-randr
screens can cause segfaults where the server touches the unset private
structure.
I audited the code and found two more possible problem spots; the
trick to auditing for this issue was to look for functions not taking
a RandR data structure and where there was no null screen private
check above them in the call graph.
