coroutine support

[Rémi Forax]

Hi Lukas, hi all,

C1 seems to work but not C2 (see further).

Furthermore by default, hotspot requires that package javax.stack exists
instead of gracefully disable coroutine if javax.stack is not here
(which is the case of the first build, i.e when you use jdk6 to compile 
jdk7).

I will test it tomorrow,
Rémi
