Debian is using cJSON from github.com/DaveGamble/cJSON, as well as
archlinux and homebrew, which is shipping a libcjson.pc file. Only
ubuntu is using a different version not including the .pc file.

Only a few of them were actually exposed to end users, while the majority
was just in code comments. Still, the latter would turn up in any future
spellchecking attempts anyways, so fixing them now as well.

Custom muxing allows the use TUN interfaces by transfering ipv4 data through OOB and/or regular rist channel
Default mux mode on sender is RIST_MUX_MODE_RAW and default mux mode on receiver is RIST_MUX_MODE_AUTO

Fixes use of mbedtls 3.0 w/ librist.

we don't rely on overflow behavior where it's relevant.

Librist currently builds with system-wide mbedtls by default.
But its code assumes mbedtls 2 (embedded mbedtls is also v2).
This creates compilation issues with mbedtls 3 due to the renaming
of various functions [1].
The commit fixes the issue by including mbedtls compatibility layer.
