[virglrenderer-devel] [PATCH 2/5] utils: added some macros for future implems

[Nathan Gauer]

This commit adds some macros designed for a future use:
ARRAY_SIZE: gives the size of an array
UNUSED_PARAMETER: cast a parameter to void. Only a bit more explicit.
TRACE_IN/TRACE_OUT: macros available in debug builds. Inspired from
virtio-gpu ones.

RETURN: encapsulates a return and a TRACE_OUT.
