* small bit of tracing cleanup
* no functional change

Committed patch by Gerald Zajac, thanks!:
* Enabled testing the checksum of the EDID info.
* Added a version check of the EDID info.
* Added more debug output.
* In the ModeList class, changes were made to how the refresh rate is
computed and used. Previously, some of the basic VESA modes were not
added to the mode list because the computed and specified refresh rates
did not exactly match. Now if the computed refresh rate is within 1.2%
of the specified rate, the mode is added. With this change, all basic
VESA modes selected by the EDID info are now added to the mode list.
* The "additional video modes" shown in the EDID dump are now added to
the mode list. Previously, this mode data was setup but not added to
the mode list. Code was also added here to set the vertical &
horizontal sync polarity according the EDID info. The sync polarities
are set according to a VESA document that I have.
* Fixed copy_str() warning, broken removal of trailing spaces, and null
termination.

Made providing a place for vdif and vdifLength optional in ddc2_read_edid1().

* Separated I2C from DDC a bit more.
* i2c_bus now contains a i2c_timing structure, so that you don't need
both to talk to the I2C bus.
* Therefore, there is now a void ddc2_init_timing() function to get the
the timing DDC needs.
* Cleanup in radeon's monitor_detection.c, and updated it to work with
the DDC/I2C changes.

Includes some common routines which can be used by other accelerants.
