color: refactor how terminfo colors are defined
Terminfo colors are currently lumped together with terminfo control
and styling attributes. As part of implementing 16 and 256 color
support, it will help to differentiate terminfo colors from other
attributes. So this commit does that.
Colors are split to their own dict. A new function for obtaining
a dict of color name to color number has been implemented and code
has been refactored to use it.
The color dict preserves whether the color is user-defined so that
`hg debugcolors` output remains consistent. I'm not sure if this is
worth it. I kept the old behavior to avoid a BC break.
