git-daemon: set REMOTE_ADDR to client address

Browse Source 
This allows hooks like pre-receive to look at the client's IP
address.

Of course the IP address can't be used to get strong security;
git-daemon isn't the right thing to use if you need that. However,
basic IP address checking can be good enough in some situations.

REMOTE_ADDR is the same environment variable used to communicate the
client's address to CGI scripts.

'git-daemon' will set REMOTE_ADDR to the IP address of the client
that connected to it, if the IP address is available. REMOTE_ADDR will
be available in the environment of hooks called when
services are performed.
