2941c2022f Refactor wasmtime-wasi crate 
Changes:
* uses Rust edition 2018
* returns wasm32 errno directly rather than relying on
  wasi_common::{host, memory} modules
* wraps extraction of memory and WASI context in a macro

36b4ff8031 Say "memory" instead of "__wasi_memory" in error messages. 
While the "__wasi_memory" name is something we considered, the name
currently being used for the memory exported to WASI is "memory", so
adjust the error message accordingly.

1aff03a5b4 dependencies: pin wasi-common to specific rev 
This removes the reliance on having a correct version of wasi-common in
the cache by chance ;-)

06b6ec42b9 Provide the C WASI implementation as an option. 
This adds the C WASI implementation as a new crate, wasmtime-wasi-c,
and adds a command-line flag to the wasmtime command-line driver to
select which WASI implementation to use.

b0eab7398d Don't decode the incoming events to poll_oneoff. (#113) 
The events array is an output-only array, so we don't need to decode its
contents.

049c926e08 Handle set-size rights correctly when truncating a file. 
If a path_open call is requesting __WASI_RIGHT_FD_FILESTAT_SET_SIZE,
interpret that as a request for write privleges. If it is requesting
O_TRUNC, require __WASI_RIGHT_PATH_FILESTAT_SET_SIZE, since this is
a path operation rather than a FD operation.

f10cd2f4b1 Don't allow a preopened file descriptor to be renamed over. 
This is consistent with fd_close's behavior, and is likely temporary
until other options are designed.

cc5efeb54d WASI: Simplify byref translation. 
Avoid needlessly copying data from wasm into the host for output
