In order to run under memfault, the framework is first extended to handle
running concurrent tests - i.e. multi-threading. (Not that this is a
requirement for memfault, instead it shares a common goal of storing
per-test data). To that end all the global data is moved into a per-test
context and the targets are adjusted to avoid overlap on shared, global
resources (such as output files and frame buffers). In order to preserve
the simplicity of the standard draw routines, the context is not passed
explicitly as a parameter to the routines, but is instead attached to the
cairo_t via the user_data.
For the masochist, to enable the tests to be run across multiple threads
simply set the environment variable CAIRO_TEST_NUM_THREADS to the desired
number.
In the long run, we can hope the need for memfault (runtime testing of
error paths) will be mitigated by static analysis. A promising candidate
for this task would appear to be http://hal.cs.berkeley.edu/cil/.

- 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.

This patch was produced by running git-stripspace on all *.[ch] files
within cairo. Note that this script would have also created all the changes
from the previous commits to remove trailing whitespace.

Add new _CHECK_FUNCS_WITH_FLAGS to abstract out the pain of temporarily setting flags for AC_CHECK_FUNCS. Use this to check for the existence of FcFini.
Make call to FcFini conditional on HAVE_FCFINI.
Remove stale comment about cleaning up memory which is now handled by cairo-test.c.

cairo_copy cairo_get_path cairo_get_path_flat cairo_matrix_create cairo_matrix_destroy cairo_matrix_copy cairo_matrix_get_affine cairo_surface_set_repeat cairo_surface_set_matrix cairo_surface_get_matrix cairo_surface_set_filter cairo_surface_get_filter
Also, eliminate all support for compiling against, or running with old, deprecated names for functions.
Deal with all of the removals.

docs/public/cairo-sections.txt: cairo_select_font() => cairo_select_font_face() cairo_scale_font() => cairo_set_font_size() cairo_transform_font() => cairo_set_font_matrix() Add cairo_get_font_matrix(). Make cairo_set_font_face() not reset the font matrix. Default the font matrix to SCALE(10). Document cairo_select_font_face().
test/text-cache-crash.c (draw) test/text-rotate.c (draw): Use cairo_set_font_size().
src/cairo-font.c src/cairo.h: Fix up some parameter names for docs.

it can indicate test failure even if there is no result image.

Add test to demonstrate bug when item is too big for cache.
Really remove that refcount assertion this time.

cache destruction.
Support tests that produce no output, (don't check image if (width,height) == (0,0)).
Add #include <assert.h> here rather than in multiple .c files.
Add const qualifier to static cache_arrangements table. (_cache_sane_state): Remove refcount assertion as it it false during the cairo_cache_destroy. (_cache_sane_state): #include <assert.h> moved up to cairoint.h (_entry_destroy): Fix bug in assertion (used_memory >= entry->memory), not >. (_cairo_cache_destroy): Fix timing of refcount decrement so that the destroy function actually works.

Add new test showing problems with rotated text.
