-Parses JSON-RPC request contained in `buf`, `len`.
-Then, dispatches the request to the correct handler method.
-Valid method names should be specified in NULL
-terminated array `methods`, and corresponding handlers in `handlers`.
-Result is put in `dst`, `dst_len`. Return: length of the result, which
-can be larger then `dst_len` that indicates an overflow.
-Overflown bytes are not written to the buffer.
