Prepare to be able to put framework-res in srcs 

This change introduces two changes required to put
framework-res explicitly in srcs property, without relying on the build
system to specially add framework-res as a dependency to
framework-minus-apex, etc.

1) R.java and Manifest.java generated from aapt were packaged to the file
R.jar directly under the gen directory. With this change, the file
becomes android/R.srcjar under the gen directory.

2) android_app module now overrides OutputFileProducer interface so that
it can recognize "{.aapt.srcjar}" tag to reference the generated srcjar file.

Being able to put framework-res in srcs allows us to pass all the source
files (both in the source tree and the ones generates) via a filegroup.
Previously, the source files could only be passed via the java_library
module type. This caused a circular dependency problem when the java
library was used as an input (src_libs) of the droiddoc module. Using
filegroup eliminates the circular dependency.
