* 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.
