Paul Drews b957c775ea Add capability to chroot to use proxies for git:// urls
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.
