*	[SERVER] Get rid of alt-servers thread, per-uplink rtt history	Simon Rettberg	2019-08-22	1	-0/+2
\| \| \| \| \| \| \| \| \| \|	Alt-Server checks are now run using the threadpool, so we don't need a queue and dedicated thread anymore. The rtt history is now kept per uplink, so many uplinks won't overwhelm the history, making its time window very short. Also the fail counter is now split up; a global one for when the server actually isn't reachable, a local (per-uplink) one for when the server is reachable but doesn't serve the requested image.
*	[SERVER] uplink: More consistent type/variable naming	Simon Rettberg	2019-08-18	1	-1/+1

*	[*] Support hop-counting in request header, protocol version 3	Simon Rettberg	2017-10-17	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	We steal 8 bits from the request offset to count hops when requests get relayed by proxies. This still leaves plenty of bits for the offset (56 bits, supporting images of up to 72 petabytes). This is used to detect proxy cycles. The algorithm is not perfect but should prevent endless relays of the same request. This is backwards compatible to old clients and servers, as the server only ever sets the hopcount in relayed requests if the upstream server is using protocol version 3 or newer, and clients are automatically upwards compatible as there is practically no image larger than 74PB, so the newly introduced hop count field is always 0 even in requests from old clients.
