Translate some ant to python

Translate some ant to python

This moves java compilation, jar, and dex for apks from
ant to python. This uses the same javac.py and jar.py
that are used by build/java.gypi for libraries and introduces a simple dex.py.

Doesn't this needed to be quoted and with a ":" separator?

maybe a verbose option, so that if one wants to debug dex phase, it is easier to
do so using gyp?

Perhaps, later we can have a nice utility method that does subprocess.check_call
and pretty prints the output.

I think that both of these are things that we may want in the future. This is
already better than ant was as it will actually print the output from the dx
call rather than suppressing it and only printing "null returned 1" on error.

Gyp expands a gyp-list (in a string context as here) as a space-separated list
of the members. This whole thing is enclosed in quotes like:
"--classpath=foo.jar bar.jar android.jar"
and python understands that. javac expects the classpath to be ":"-separated and
that transformation is done in javac.py.
