// packeted_bio_create creates a filter BIO for testing protocols which expect
// datagram BIOs. It implements a reliable datagram socket and reads and writes
// packets by prefixing each packet with a big-endian 32-bit length. It must be
// layered over a reliable blocking stream BIO.
//
// Note: packeted_bio_create exists because a SOCK_DGRAM socketpair on OS X is
// does not block the caller, unlike on Linux. Writes simply fail with
// ENOBUFS. POSIX also does not guarantee that such sockets are reliable.
