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.

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> @@

65e5824d3a Add new fuzz binary.
This is designed to have short startup time, for maximum fuzzing throughput.
