[PATCH 02/14] http: turn off curl signals

[Jeff King <peff@peff.net>]

Curl sets and clears the handler for SIGALRM, which makes it
incompatible with git's progress code. However, we can ask
curl not to do this.

I'm a little iffy on this one. If I understand correctly, depending on
the build and configuration, curl may not be able to timeout during DNS
lookups. But I'm not sure if it does, anyway, since we don't set any
timeouts.

An alternate plan would be to give the progress code a mode where it
gets poked by curl every second or so (curl has a PROGRESSFUNCTION
option for doing this).
