Original bt709 color space coefficients were full range yuv for higher
quality. This change makes the coefficients use the video constrained
color space the same as bt601 which is 16 to 240 for Y and 16 to 235 for
chroma channels.

Instead of creating symlinks on Windows, the script is now:
* creating a junction for directories
* copying individual files.
This makes 'gclient sync' and 'gclient runhooks' no longer
require administrator's privileges.
If the script is run with administrator's privileges, a
warning will be printed, informing the user that it's not recommended.
Also clean up a few old documentation references to the
Chromium SVN->Git transition.

TESTED=Running the script with+without administrator's privileges.
I also tested the case of this change being rolled back, in which
case I verified that the copied files are still being deleted using
the same cleanup code path as the previous symlinks.
