[PATCH 8/9] Support more http features: https no cert, .netrc -> auth

[Junio C Hamano <junkio@cox.net>]

From: Darrin Thompson <darrint@progeny.com>
Date: 1121220760 -0500

Cause setting environment variable GIT_SSL_NO_VERIFY to turn off
curl's ssl peer verification.

Only use curl for http transfers, instead of curl and wget.

Make curl check ~/.netrc for credentials.
