auth: don't trust clients too much - only trust the *last* IP in the X-Forwarded-For header
The X-Forwarded-For header contains a list of IP addresses, where each
proxy server appends the IP they see their request coming from.
See https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Forwarded-For .
Trusting the *first* IP in HTTP_X_FORWARDED_FOR would allow clients to claim
any IP, which could be used to bypass IP restrictions configured in Kallithea.
Instead, only trust the last proxy in the chain, and thus only use the *last*
IP in HTTP_X_FORWARDED_FOR. (In setups where more than last IP should be
trusted, the last proxy server in the chain must be configured rewrite the
header accordingly.)
