Uses gyp "rules" rather than "actions" templates for the JNI generator.

Uses gyp "rules" rather than "actions" templates for the JNI generator.

This allow finer grain control over what is rebuilt.
Also, since we have approval over the generated header file name,
it greatly simplifies both the generator and also all the gyp files
as they no longer need to list the header file and keep in sync with the
java file, so the process now is as simple as adding a single java file
to the sources.

yfriedman: would you mind a sanity check before sending out to the respective
owners please?

I think this definitely fits the bill for TBRing as aside from the jni-generator
change this is mechanical. I'd say to just get a stamp from someone like mark or
rsleevi who've been involved with the Android jni/gyp tools.

+mark, rsleevi

thanks yaron!

mark, ryan: these changes are a sort of follow up from:
http://codereview.chromium.org/10081035/

since you guys seemed to be happy with auto-generated header files in
CamelCase.h, we could simplify our gyp actions and use simpler rules instead...

would you mind taking an overall look please?
no need to look at the the .cc files, they were mostly mechanical changes to
replace:
#include "jni/foo_bar.h"
to
#include "jni/FooBar.h"

but please do look at the gyp :)
