This shouldn't matter... But I just feel the impulsion to fix it.

This will be rolled out in three stages:
1) make SkMemory.h and have SkTypes.h include it.
2) Adjust chromium and android.
3) no long include SkMemory.h in SkTypes.h

We use this approach instead of T next() because different compilers
evaluate function parameters in different orders. If fuzz->next()
returned 5 and then 7, foo(fuzz->next(), fuzz->next()) would be
foo(5, 7) when compiled on GCC and foo(7, 5) when compiled on Clang.
By requiring params to be passed in, we avoid the temptation to call
next() in a way that does not consume fuzzed bytes in a single
platform-independent order.

signalBoring() no longer exists. When the fuzzer runs out of randomness,
it just returns 0. Fuzzers should not go into infinite loops if this
happens. do while loops are particularly error-prone.

With the move from SkData::NewXXX to SkData::MakeXXX most
SkAutoTUnref<SkData> were changed to sk_sp<SkData>. However,
there are still a few SkAutoTUnref<SkData> around, so clean
them up.

Instead of a single ASSERT macro, this switches to two new methods:
- signalBug(): tell afl-fuzz there's a bug caused by its inputs (by crashing)
- signalBoring(): tell afl-fuzz these inputs are not worth testing (by exiting gracefully)
I'm not seeing any effect on fuzz/s when I just always log verbosely.
signalBug() now triggers SIGSEGV rather than SIGABRT. This should make it work with catchsegv more easily.

Try to start faster:
- remove flags dependency
- print nothing
- strip unused symbols from the binary on Mac (smaller binary)
- only create one fuzz object
- only run one DEF_FUZZ
I am not sure if any of these things mattered, but I thought you may like to look.
Good stuff:
- make nextU() / nextF() work
- drop nextURange() / nextFRange() for now
- add nextB() for a single byte
As you may have guessed, I have figured out how to use afl-fuzz on my laptop.
Syntax to run becomes:
$ afl-fuzz ... out/Release/fuzz <DEF_FUZZ name> @@
