[PATCH 5/7] http: init and cleanup separately from http-walker

[Tay Ray Chuan <rctay89@gmail.com>]

Previously, all our http operations were done with http-walker. With the
new remote-curl helper, we find ourselves using http methods outside of
http-walker - for example, fetching info/refs.

Accomodate this by separating http_init() and http_cleanup() invocations
from http-walker.
