[xserver PULL master] randr fixes + primary GPU fallback

[Hans de Goede]

Hi Adam, Keith,

Here is a pull-req consisting of 2 different patch-sets:

1) 2 randr fixes for sometimes the screen pixmap being
too small when using slave outputs, these have been
Reviewed-by Dave Airlie

2) 3 xfree86 patches which together make the xserver
choice the first available device, rather then exiting
with a "No screens" error, when output devices are found,
but non is recognized as being the primary / boot display
adapter. This is necessary at least for the simpledrm
kms driver, which due to its nature does not get recognized
as being the boot display. These 3 patches are *unreviewed*,
but have been part of the Fedora xserver pkg since F25 beta
and have shown no issues, as such I believe these are ready
for merging.

The following changes since commit e1d30075c923f96a375895d74ea12a3c92a640c6:

p.s.

Talking about unreviewed patched it would be really good to get
a review of / some discussion on:

https://patchwork.freedesktop.org/patch/112579/

Which is the last magic sauce in the Fedora xserver pkgs and
is really important for a smooth ootb experience on laptops
with hybrid gfx.
