LDPRELOAD: Add ioctl, fcntl, and setsockopt support
Add support for the following system calls:
ioctl (FIONREAD)
fcntl (F_GETFL)
fcntl (F_SETFL)
setsockopt (SOL_IPV6, IPV6_V6ONLY)
setsockopt (SOL_TCP, TCP_NODELAY)
setsockopt (SOL_SOCKET, SO_REUSEADDR)
setsockopt (SOL_SOCKET, SO_BROADCAST)
This patch supersedes https://gerrit.fd.io/r/#/c/8765/
