    Rewrite the Revision Walker
    
    The new revision walker uses an internal Commit object storage system,
    custom memory allocator and much improved topological and time sorting
    algorithms. It's about 20x times faster than the previous implementation
    when browsing big repositories.
    
    The following external API calls have changed:
    
    	`git_revwalk_next` returns an OID instead of a full commit object.
    	The initial call to `git_revwalk_next` is no longer blocking when
    	iterating through a repo with a time-sorting mode.
    
    	Iterating with Topological or inverted modes still makes the initial
    	call blocking to preprocess the commit list, but this block should be
    	mostly unnoticeable on most repositories (topological preprocessing
    	times at 0.3s on the git.git repo).
    
    	`git_revwalk_push` and `git_revwalk_hide` now take an OID instead
    	of a full commit object.
