Dispatches a JSON-RPC request.

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.
If method is not found, an error is automatically generated.
