Add support for arm printf extension. (#434)

Browse Source 
The cl_arm_printf extension uses a call-back to tell the user-code
that some printf output has appeared from the execution of the CL
kernel.

The extsiting Printf tests assume output to stdout.

This change adds code to detect the cl_arm_printf extension, and an
implementation of the callback code to write to stdout.

Also fix a couple of formatting errors and don't "poll" when waiting
for events.
