This commit adds a bt_sock_stream_recvmsg() function for use by any Bluetooth code that uses SOCK_STREAM sockets. This code is copied from rfcomm_sock_recvmsg() with minimal modifications to remove RFCOMM-specific functionality and improve readability. L2CAP (with the SOCK_STREAM socket type) and RFCOMM have common needs when it comes to reading data. Proper stream read semantics require that applications can read from a stream one byte at a time and not lose any data. The RFCOMM code already operated on and pulled data from the underlying L2CAP socket, so very few changes were required to make the code more generic for use with non-RFCOMM data over L2CAP. Applications that need more awareness of L2CAP frame boundaries are still free to use SOCK_SEQPACKET sockets, and may verify that they connection did not fall back to basic mode by calling getsockopt().
