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.

Make fuzz::next overloads more consistent Some oss-fuzz bugs (like the linked one) would not reproduce in Skia proper due to the fact that there were subtle overloads of the various Fuzz::next() methods in FuzzCanvas.cpp that were pulled in in Skia proper, but not oss-fuzz. This puts all of them in to FuzzCommon.h and makes the matrix and rrect ones opt-in (fuzz_matrix, fuzz_rrect). Additionally, this renames fuzz.cpp -> FuzzMain.cpp so we can properly include Fuzz.cpp in oss-fuzz without having two mains.

simplify nextRange(), fold in nextEnum() Doesn't look like we need to distinguish these if we just write them as the simple 1) load the right number of bytes 2) clamp to [min,max] This makes enum fuzzing independent of its underlying type, and may make it easier to see the mapping from fuzzed byte stream to nextRange()/nextEnum() values.
