Fix the Android Eclipse CDT generator.

Fix the Android Eclipse CDT generator.

This fixes a couple of problems:
- CONFIGURATION_NAME is now getting set. This seems to be a required
  variable now.
- Macro values are now escaped before getting written to the XML out
  in order to handle macros with XML syntax.

Does this require a deps roll as well?

Should this CL be closed?

Yes. (By the way, you can close other people's CLs. I went ahead and did that.)
