Debug issue #10876433 java.lang.IllegalStateException...

...in ActivityManagerService.updateLruProcessInternalLocked on bluetooth

Add more debug output to help track down what is going on.

Also fix a little problem where, when a service ANRs, if you ask to
wait and it still wasn't responding, the ANR dialog wouldn't be
shown again.
