Crate gear_dlmalloc

A Rust port of the dlmalloc allocator.

The dlmalloc allocator is described at http://g.oswego.edu/dl/html/malloc.html and this Rust crate is a straight port of the C code for the allocator into Rust. The implementation is wrapped up in a Dlmalloc type and has support for Linux, OSX, and Wasm currently.

The primary purpose of this crate is that it serves as the default memory allocator for the wasm32-unknown-unknown target in the standard library. Support for other platforms is largely untested and unused, but is used when testing this crate.
