This function is the equivalent to the function used to set the UDP
receive buffer size. It's so similar that code generation is used to
make a copy of the setReceiveBuffer function.
* Add ability to force change the receive buffer size using SO_RCVBUFFORCE in Linux
* Fix imports
* Update test
* Add sys_conn_helper_not_linux
* Rename file
* ignore the error on SetReadBuffer
* also run unit tests as root
