Updated build.rs to tell RustC that dxgi, quartz and x11 are expected configurations.

Added lifetime annotations to various methods in common/aom.rs and common/vpxcodec.rs.
Updated common/vpx.rs to allow unused_imports in the generated bindings.
Updated dxgi/mag.rs to allow non_snake_case identifiers like "dwFilterMode".
