Parse new fonts.xml config file, and resolve weight selection based on
the base weight of the font (as defined by a weight alias specified in
the config file) and the requested bold flag. This change improves the
appearance of bold spans for alternate weights of Roboto.
In addition, this patch enables weight selection for fallback fonts.
For example, if an additional font with a weight of 100 is added to the
Hebrew font family in the fallback list, then requesting
"sans-serif-thin" would select that font for Hebrew text.

This adds a new configration file for fonts with several more features,
most notably the ability to specify numeric weights for fonts in a
family, and specify aliases for weights. This will help help choose an
appropriate font for a "bold" weight request, rather than just applying
auto-bolding.

Also parse fallback_fonts.
This lets layoutlib automatically use the same fonts as the base
platforms, for instance it now uses the new ICS fonts.
