2a42f48b58 Add ability to fuzz images using scaling and different modes 
This also fixes the tryAllocPixels/SkColorTable mismatch which was causing the
"Image might be too large (32 x 32)" problems.

47d158eb3c Make fuzz broadcast when it terminates via return. 
This helps analysis figure out things like timeouts and unexpected, uncaught
exits.

2b6aa21817 Make fuzz output the words success for a 'clean exit' 
The analysis looks for "Success" to determine if the fuzz should be considered
a clean exit or not.  It classifies clean exists as "grey" fuzzes, i.e. fixed.

d4387ea993 fuzz: list API fuzzing options if -t api and -n matches nothing. 
Today we segfault if --name is empty.  This fixes that too.

This updates some terms: -t api lets us fuzz an API.

dba5734409 Seperating our fuzzing binary from DM produces a 50x speed increase for decoding images and a 10x speed increase in decoding/rendering Skps. 
This also lets us differentiate between the decoding of Skps and the rendering of them, the latter of which may be more interesting for bugs.

d0b823479a If we pass no bytes, use the fuzz binary itself. 
This is mostly for convenient local testing.

f5e9782bde Restore creature comforts to fuzz binary 
The hack to remove these niceties didn't seem to make a difference in my
fuzz/s, so we might as well keep them.

a115942ed6 fuzz: signalBug() / signalBoring() 
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.

24a22c7de8 some fuzz hacking 
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> @@

This is designed to have short startup time, for maximum fuzzing throughput.
