Merge #6202
6202: Add tool to manually ping the mastersrv r=def- a=heinrich5991 Usage example: `masterping ipv6 https://master1.ddnet.org/ddnet/15/register`. Returns 0 on success, nonzero on failure. Note that this might report failure occasionally as it doesn't retry, UDP packets are non-reliable so they might not arrive even though the mastersrv is up. ## Checklist - [x] Tested the change ~~ingame~~ - [ ] Provided screenshots if it is a visual change - [ ] Tested in combination with possibly related configuration options - [ ] Written a unit test (especially base/) or added coverage to integration test - [ ] Considered possible null pointers and out of bounds array indexing - [ ] Changed no physics that affect existing maps - [ ] Tested the change with [ASan+UBSan or valgrind's memcheck](https://github.com/ddnet/ddnet/#using-addresssanitizer--undefinedbehavioursanitizer-or-valgrinds-memcheck) (optional) Co-authored-by: heinrich5991 <heinrich5991@gmail.com>
