Low-level bindings to the libuv library.
This module contains a set of direct, 'bare-metal' wrappers around
the libuv C-API.
Also contained herein are a set of rust records that map, in
approximate memory-size, to the libuv data structures. The record
implementations are adjusted, per-platform, to match their respective
representations.
There are also a collection of helper functions to ease interacting
with the low-level API (such as a function to return the latest
libuv error as a rust-formatted string).
As new functionality, existant in uv.h, is added to the rust stdlib,
the mappings should be added in this module.
This module's implementation will hopefully be, eventually, replaced
with per-platform, generated source files from rust-bindgen.
