[PATCH 0/10][Precise][SRU]: (upstream) bring edid resolution detection in parity with quantal

[Dave Chiluk]

BugLink: http://bugs.launchpad.net/bugs/1109112

SRU Justification:

Impact: Users may not be able to mirror displays between two displays
   that support the same possible resolutions.

   One such example is connecting a particular 1920x1080 display to a 1368x768
   laptop.  Since the external display does not show 1368x768 as a valid
   resolution, both displays are instead run at 1024x768 by default.  In
   Quantal where 1368x768 is detcted as valid both displays are mirrored at
   1368x768, which is preferable.

Fix:
 These commits update the range descriptor struct for edid 1.4.

 These commits add a number of inferred modes through calculation

 These commits remove a number of newly inferred modes to attain parity with
  quantal.

  cffd75480ceb1cefffb5595b03ce8383d0ba40ad

 Together these patches allow for resolution parity with quantal.

Testcase:
   Using a machine with quantal and raring compare the output of xrandr on
   both series.  This fix should make the resolution output similar, but
   not necessarily identical.
