Run CanvasState test across a library boundary. Refactor CanvasStateTest to pull out functions which can either be called directly or from a shared library. Add a command line flag to pass in the path to a library to open to call those functions from. Separate different CanvasTest tests into separate DEF_TEST tests. This allows them to be run in parallel. Move the ifdefs outside of function declarations to skip running CanvasTest tests which do nothing. Add the canvas_state_lib target. It is a shared library that exports some functions to be called by another version of Skia.

rewrite includes to not need so much -Ifoo Current strategy: everything from the top Things to look at first are the manual changes: - added tools/rewrite_includes.py - removed -Idirectives from BUILD.gn - various compile.sh simplifications - tweak tools/embed_resources.py - update gn/find_headers.py to write paths from the top - update gn/gn_to_bp.py SkUserConfig.h layout so that #include "include/config/SkUserConfig.h" always gets the header we want.

Improve CanvasState cross-library tests Several things are accomplished as part of this: 1. The canvas_state_lib build target is brought back so that we can actually test the canvas state sharing across library boundaries. 2. The canvas state helper functions are updated to work with DLLs (confirmed tests pass on Windows in cross library mode) 3. The tests now always run, and the cross-state define only changes what version of the helper functions are used 4. Updated the dlopen code in the test to use the SkOSLibrary ports instead of calling dlopen/dlclose directly. 5. Fix bugs in SkCanvasStateUtils that were uncovered as part of always running these tests. 6. Switches the define away from SK_SUPPORT_LEGACY_CLIPTOLAYERFLAG to SK_TEST_CANVAS_STATE_CROSS_LIBRARY, since these tests are not strictly speaking testing the unclipped layer feature.

// See CanvasStateTest. These functions are either linked in to 'dm' directly (when this flag is
// not defined), or built in a shared library that is dlopened by the test. In that case, they
// should not be visible in 'dm', but the shared library will not have this flag set and compiles
