555: wasi filesystem rewrite + implementation of many syscalls r=MarkMcCaskey a=MarkMcCaskey
This lets the go compiler print its help text...
The rest of symlink code to follow...
This PR also does a major refactor of the file system code. So we'll have to add more tests to be sure we didn't break anything

These is one test failure remaining with V128 global variables.
* Fix trunc_sat. We need both the largest float that can be converted to an int
and the largest int, they are not the same number.
* Implement calling of functions that take V128 by passing in two i64's.
* Improve support for V128 in spectests. Parse binary modules with the same
features as the outer spectest. Fix compilation error involving Result in
emitted .rs file. Handle V128 in more cases when producing .rs file. Parse
the wast script with SIMD enabled.
* Adjust the WAVM spectest so that it parses with WABT and mostly passes with
wasmer. Wabt is particular about ints not having decimal places and floats
having decimal places. Wasmer does not support mutable globals or shared
memory. Tests of shuffles are disabled. Some assert_invalid tests that wabt
won't even parse are disabled.
"Then thou must count to three. Three shall be the number of the counting and the number of the counting shall be three. Four shalt thou not count, neither shalt thou count two, excepting that thou then proceedeth to three."
559: Initial commit of a fuzzer. Run with "cargo fuzz run simple_instantiate". r=nlewycky a=nlewycky
Used to discover issue #558.
We'll probably want to reconsider the default .gitignore of the artifacts and corpus directories. The fuzzer wastes a lot of time not having even a single exampel of a valid .wasm file to start with.

557: Update loader-kernel feature name, fix compilation track state r=syrusakbary a=bjfish
- feature name `loader:kernel` -> `loader-kernel` (no colons)
- add track state `false` to loader kernel default, @losfair let me know if this default is incorrect
- cargo fmt

552: Allow disabling state tracking for faster startup. r=bjfish a=losfair
~10% compilation speedup when `--no-track-state` is enabled.
