This is a NOP for existing usecases. At the moment the only implemented transport for serialized SS is wsi, it's typically used with Unix Domain Sockets, but it also works over tcp the same. It generalizes the interface between serialized chunks and the transport, separately for client and proxy. The wsi transport is migrated to use the new transport ops structs. It will then be possible to "bring your own transport", so long as it is reliable, and in-order, both for proxy and client / sspc. We also adapt minimal-secure-streams-binance to build the -client variant via SS proxy as well. LWS_ONLY_SSPC is added so libwebsockets can be produced with just sspc client support even for tiny targets. A new embedded minimal example for rpi pico is also provided that demonstrates using Serialized SS over a UART to an SS proxy, to implement the SS Binance example on the pico, even though it has no networking itself. |

lws minimal secure streams policy2c
This application parses a JSON policy passed on stdin and emits the equivalent of it in C structs ready for compilation.
This is useful in the case your platform doesn't use a dynamic JSON policy and is space-constrained, you can still form and maintain the policy in JSON, but with this utility convert it into compileable C.
Notice this depends on LWS_ROLE_H1, LWS_ROLE_H2, LWS_ROLE_WS and LWS_ROLE_MQTT build of lws, since it has to be able to work with any kind of policy content.
