bionic_systrace.h contains an implementation of tracing that can be used with systrace.py and its associated viewer. pthread_mutex now uses this tracing to track pthread_mutex contention, which can be enabled by using the "bionic" command line option to systrace. Bug: 15116468 Change-Id: I30ed5b377c91ca4c36568a0e647ddf95d4e4a61a
