[PATCH 0/4] Modularize http, commit-walker, http-fetch

[Daniel Barkalow]

This series cleans up a whole lot of flow control and makes it possible to 
extend commit-walkers and http (each individually) in more useful 
directions.

Due to the limitations on what I can test, it could use a bunch more 
testing before it goes in. In particular, http-push is completely 
untested, and I haven't really beaten on USE_CURL_MULTI, although it 
compiles each way.

The first patch just makes the http library code easier to work with.

The second patch turns the caller-provided global function for making 
delayed requests into a callback in a chain.

The third patch (posted previously) removes obsolete commit-walkers.

The fourth patch (posted previously) reworks the commit-walker framework, 
and makes http-fetch into a commit-walker implementation which can be used 
from library code. It also turns http-fetch into a (trivial) builtin which 
calls the walker code with the library walker.

I just realized I forgot to use -C, so some of these patches are probably 
less than trivial to review as changes. If anybody wants to be able to 
actually read them all without applying them, I have -C versions; if 
nobody does, I'd just as soon not spam the list further.
