http-fetch: support fetching packfiles by URL

Teach http-fetch the ability to download packfiles directly, given a
URL, and to verify them.

The http_pack_request suite has been augmented with a function that
takes a URL directly. With this function, the hash is only used to
determine the name of the temporary file.

SYNOPSIS

'git http-fetch' [-c] [-t] [-a] [-d] [-v] [-w filename] [--recover] [--stdin] <commit> <url>

DESCRIPTION
-----------
@ -40,6 +40,13 @@ commit-id::
<commit-id>['\t'<filename-as-in--w>]
--packfile=<hash>::
Instead of a commit id on the command line (which is not expected in
this case), 'git http-fetch' fetches the packfile directly at the given
URL and uses index-pack to generate corresponding .idx and .keep files.
The hash is used to determine the name of the temporary file and is
arbitrary. The output of index-pack is printed to stdout.
--recover::
Verify that everything reachable from target is fetched. Used after
an earlier fetch is interrupted.
