color: move 'write' logic to the core ui class

One more step, the support for writing color is not directly in core. No
behavior change for the default case ('_colormode' = None).

Here are the details of what we have to change to the core method:

 * apply to 'self.label' to input in the buffered case
 * dispatch to 'win32print' when applicable
 * apply to 'self.label' to input when applicable

"""test behavior of propertycache and unfiltered propertycache

The repoview overlay is quite complex. We test the behavior of
property cache of both localrepo and repoview to prevent
regression."""
