Stop Android logging from consuming significant CPU (on every input event).
(LP: #1343074)

Two things needed fixing:
  1. Verbose logging (ALOGV) is meant to be disabled (optimized out) unless
     debugging, but it wasn't ever being removed. This means expensive calls
     to ALOGV remained, for example in EventHub.cpp on every input event.
  2. Our own Mir version of __android_log_print was extremely inefficient,
     formatting log messages unconditionally even when they did not meet the
     reporting threshold and were never used.
