Strip net.c down to the bare minimum

/* Extracted from anet.c to work properly with Hiredis error reporting.
hiredis was extracted from redis-tools, reverted to standard malloc/free, ported to the new protocol, and started as a stand alone project in order to support the need of a C client in the Redis community

Move network I/O calls to net.c This makes hiredis.c free from system calls related to socket I/O. This is also makes the treatment of raw socket connections more similar to the SSL backend.

Remove possiblity of multiple close on same fd With all the async connects and disconnects and error handling going on in hiredis, we need to centralize how we close our fd and set it so it doesn't get re-closed. Prior to this commit, sometimes we'd close(fd), run an async error handler, then call close(fd) again. To stop multiple closes, we now set fd to -1 after we free it, but that requires not passing fd as an independent argument to functions. This commit moves all fd usage to c->fd. Since the context has a fd field and all functions receive the context, it makes more sense to use the fd inside of c instead of passing along fd as an independent argument. Also, by only using c->fd, we can set c->fd after we close it to signify we shouldn't re-close the same fd again. This does change one semi-public interface function redisCheckSocketError() to only take (context) instead of (context, fd). A search on github returned zero occasions of people using redisCheckSocketError() outside of net.{c,h} in hiredis itself. Commit inspired by the bug report at: https://groups.google.com/forum/#!topic/redis-db/mQm46XkIPOY Thanks go out to Thijs for trying high-frequency reconnects on a host that isn't there. Closes #230

Mark the timeout parameter as const in various functions The struct timeval argument in redisConnectWithTimeout(), redisConnectUnixWithTimeout(), redisSetTimeout(), redisContextSetTimeout(), redisContextConnectTcp() and redisContextConnectUnix() is never modified and can therefore be marked as const.

Add ability to bind source address on connect Some environments require binding to specific source addresses instead of letting the system determine which IP a connection should originate from. Closes #233
