v0.0.9

Notable changes:

- A DEBUG() macro and UVWASI_DEBUG_LOG build option have been
  added to improve debugging.
- Path length restrictions have been removed across the codebase.
- Initial support for poll_oneoff() has been added on all
  platforms. The implementation is based on uv_poll_t's.
- A new uvwasi_size_t has been introduced across the WASI system
  call API. This provides consistent 32-bit size_t's.
- The cmake test targets are now only generated if uvwasi is the
  root project to avoid conflicts with targets from embedders.
- uv.h has been removed from the public headers.
- A serialization/deserialization API has been added to simplify
  the process of working with WASM memory. This also hides many
  WASI <--> WASM interfacing implementation details from
  embedders.
- A memory corruption bug on Windows related to path resolution
  has been fixed.
