- android::pidToUid() additional checking. Make sure if we have to
convert a PID to an UID that the parse of /proc/<pid>/status
requires a trailing space after the number
- android::tidToPid() added, in the same vein as android::pidToUid().
- stats.tidToPid() added
- If no credentials, set PID to 0 and UID to DEFAULT_OVERFLOWUID
- If credentialed PID is 0, use stats.tidToPid()
- If credentialed UID is DEFAULT_OVERFLOWUID, use stats.pidToUid()
Test: remove +passcred from logd.rc for daemon and confirm very few
UID=65534 or PID=0 cases actually show up
