2202: Send DDNet version early in the connection process r=Learath2 a=heinrich5991

This gets rid of the problem that we don't know whether we should send
full snapshots to clients because they haven't told us about them being
DDNet yet.

heinrich5991 8d04e7e5e1 Share libcurl resources across requests
Use the libcurl-share interface to share DNS cache and connections
between different requests.

If compiled with OpenSSL, libcurl can only be safely used from multiple
threads for OpenSSL >= 1.1.0, but this problem is not newly introduced
by this commit: According to libcurl-thread(3):

>OpenSSL <= 1.0.2 the user must set callbacks.

heinrich5991 ca8fcc823c Use more secure hash function for map downloads
SHA256 was chosen because it is reasonably standard, the file names
don't explode in length (this rules out SHA512) and it is supported by
basically all versions of OpenSSL (this rules out SHA512/256 and SHA3).

The protocol is changed in a backward compatible way: The supporting
server sends the SHA256 corresponding to the map in the `MAP_DETAILS`
message prior to sending the `MAP_CHANGE` message. The client saves the
SHA256 obtained from the `MAP_DETAILS` message until the next
`MAP_CHANGE` message.

For servers not supporting this protocol, the client falls back to
simply opening maps like in the previous scheme.

Remove the `map_version` tool, it is not being used and would have been
a little bit effort to update.

Use the OpenSSL implementation of SHA256 if it is supported, otherwise
fall back to a public domain one.

Fix #1127.

heinrich5991 36694d3852 Add a way to call for external moderator help
This is done by HTTP POSTing to a location specified by
`sv_modhelp_url`. We also provide a `src/modhelp/server.py` which can
use theses POSTs to forward them to Discord servers.

The POST contains a JSON object payload, with the keys `"port"` which
contains the server port, `"player_id"` which contains the calling
player's client ID, `"player_name"` which contains the calling player's
nick and `"message"` which is the user-specified message.

Make JSON-escaping function public, add tests and fix bugs uncovered by
these tests.

Supersedes #1129.

heinrich5991 6ef9c8dbcd First working version of teehistorian
teehistorian records all inputs from the players as well as the player
positions in each tick. It stores this info in a highly compressible
output format (I've achived 5x compression using xz or bz2).
