After thinking it over a lot it made more sense for the core to deal with
the output polling especially so it can notify X.

v2: drop plans for fake connector - per Michel's comments - fix X patch sent to xorg-devel, add intel polled/hpd setting, add initial nouveau polled/hpd settings.

v3: add config lock take inside polling, add intel/nouveau poll init/fini calls

v4: config lock was a bit agressive, only needed around connector list reading.
otherwise it could re-enter.

On systems with the tv dac shared between DVI and TV,
we can only use the dac for one of the connectors.
However, when using a digital monitor on the DVI port,
you can use the dac for the TV connector just fine.
Check the use_digital status when resolving the conflict.

On X startup we were getting a flicker where there shouldn't have been one.
the X DDX calls the kernel to set the properties to the same values (yes
it could be smarter), however the kernel was doing a pointless modeset then,
making my nice smooth boot ugly.

This breaks the connection between the core drm connector list
and the fbdev connector usage, and allows them to become disjoint
in the future. It also removes the untype void* that was in the
connector struct to support this.

All connectors are added to the fbdev now but this could be
changed in the future.

This is strange - like really really strange, twilight zone of strange.
VGA ports have DDC buses, but sometimes for some reasons the BIOS
says we don't and we oops - AMD mentioned bios bugs so we'll have
to add quirks.

This fixes LVDS on some mac laptops without a panel edid.

v2 - Set proper mode type flags
v3 - Note that this is not neceesarily the exact panel mode,
but an approximation based on the cvt formula.  For these
systems we should ideally read the mode info out of the
registers or add a mode table, but this works and is much
simpler.
v4 - Update comments and debug message.

Some systems have multiple connectors connected to the same encoder;
e.g., DVI and HDMI connected to the same encoder with the same ddc
line. Since we expose connectors as xrandr outputs, randr treats them
separately which results in it trying to source the same encoder to
different crtcs. If we have an HDMI and DVI-D port on the same encoder,
pick the one to be considered connected based on the edid (HDMI if edid
indicates HDMI, DVI otherwise).

On broken EDID we were reporting vga connector to be disconnected
even if ddc probe did found a monitor. This patch report that the
connector is connected on such case. This allow drm to add a fail
safe mode (800x600 at the time of this patch) thus user can boot
and later add a mode which match its monitor capabilities.
