Wasi snapshot preview1 (#140)
* Make __wasi_linkcount_t a uint64_t (#134)

Refs: https://github.com/WebAssembly/WASI/pull/127

* Generate the WASI interface from witx.

This replaces the hand-maintained <wasi/core.h> header with a
<wasi/api.h> generated from witx.

Most of the churn here is caused by upstream WASI renamings; hopefully
in the future ABI updates will be less noisy.
