[cairo] [PATCH] test and util: maintain consistency in the usage of ARRAY_LENGTH macro

[Ravi Nanjundappa]

ARRAY_LENGTH macro is used in perf's cairo-perf.h, src's cairoint.h,
test's cairo-test.h and in some internal header files of util's
directory.So to maintain consistency ARRAY_SIZE is replaced with
ARRAY_LENGTH macro.
