More test suite infrastructure improvements:

- Remove cairo_test_expect_failure.  cairo-test.c now checks
  env var CAIRO_XFAIL_TESTS to see if the running test is
  expected to fail.  The reason for expected failure is
  appended to the test description.
- Test description is written out.
- Failed/crashed tests also write a line out to stderr (in red),
  so one can now redirect stdout to /dev/null to only see failures.
- cairo_test() has been changed to not take the draw function
  anymore, instead, draw function is now part of the test struct.
- "make check" doesn't allow limiting backends to test using env
  var anymore.  To limit backends to test, one should use the
  TARGETS variable on the make command line.
- "make check-valgrind" now writes its log to valgrind-log instead
  of valgrind.log, to not interfere with test log file processing.
