dde_linux: KMS-based Intel framebuffer driver (II)

Browse Source 
* enable i915 driver from Linux 3.14.5
* tested for generation 5 till 8 GPUs

The driver can be configured at run-time via the config ROM. Every
connector of the graphic card can be configured separately using the
following syntax

  <config>
    <connector name="LVDS-11" width="1280" height="800" enabled="true"/>
  </config>

Also, when enabled within the intel framebuffer driver configuration like
the following

  <config buffered="yes"/>

a simple ram dataspace is propagated to the client and the driver
itselfs copies from that buffer to the framebuffer triggered via refresh
calls. This option is useful to alleviate tearing effects.

The  driver distributes all available connectors of the graphic card and
their supported resolutions via a report. It looks like follows

  <connectors>
    <connector name="LVDS-11" connected="1">
      <mode width="1280" height="800" hz="60"/>
      ...
    </connector>
    ...
  </connectors>

The driver distributes the report only if this is stated within its
configuration, like the following

  <config>
    <report connectors="yes"/>
  </config>
