This patch installs "socat" and a proxy gateway script into the chroot so that git can use a proxy to access "git://" protocol urls. This is needed when performing builds from behind a firewall that requires a proxy. The script reads the proxy environment variables all_proxy (SOCKS), https_proxy (CONNECT), and http_proxy (CONNECT), in order of preference, and supports no_proxy as a whitelist of target hosts that must NOT go through the proxy. This also updates enter_chroot.sh to automatically use this script as GIT_PROXY_COMMAND when it sees the proxy environment variables set. The "socat" program is added to hard-host-depends as a separate patch. That handles socat installation in case of building a chroot from scratch or upgrading. The proxy-gw script is installed in the src/scripts/bin directory which can be stably referenced within the chroot as /mnt/host/source/src/scripts/bin/. The "/mnt/host/source" portion of this path is obtained from the CHROOT_TRUNK_DIR environment variable which is set to a suitable value by preexisting logic in common.sh. This change became necessary to unbreak builds behind proxies with the recent addition of two ebuilds using egit.eclass with repositories using git:// URLs.
