Some debugging support.

- New feature to "am monitor" to have it automatically launch
  gdbserv for you when a crash/ANR happens, and tell you how to
  run the client.

- Update dumpstate to match new location of binder debug logs

- Various commented out logs that are being used to track down
  issues.
