Fix detaching a debugger while threads are suspended.

The interesting part of this change is in "thread_list.cc".

I've done a TODO in TagFromClass, but haven't seen it make any practical
difference in a debugger. I also tightened up the types in GetThreadStatus
while investigating the fact that we report some threads as "RUNNING, SUSPENDED",
which makes no sense until you realize that TS_RUNNING corresponds to both
our kRunnable thread state and our kNative thread state, the latter of which
may actually be a suspended thread.

I've also made us fail faster in the "address in use" jdwp failure case,
and tidied up a bunch of the capitalization in logging.
