[RFA] Mostly implement JVMTI's GetThreadState

[Keith Seitz]

Hi,

I posted last week about what a pain it is turning out to implement this 
function fully. I hate to do this, but I'm going to have to ask 
maintainers to consider a patch which does not fully implement this 
function. This is a real blocker for continued JDWP testing with Eclipse.
