2020-12-11[netstack] Decouple tcpip.ControlMessages from the IP control messges.Ayush Ranjan
tcpip.ControlMessages can not contain Linux specific structures which makes it painful to convert back and forth from Linux to tcpip back to Linux when passing around control messages in hostinet and raw sockets. Now we convert to the Linux version of the control message as soon as we are out of tcpip. PiperOrigin-RevId: 347027065

2020-12-03Implement `fcntl` options `F_GETSIG` and `F_SETSIG`.Etienne Perot
These options allow overriding the signal that gets sent to the process when I/O operations are available on the file descriptor, rather than the default `SIGIO` signal. Doing so also populates `siginfo` to contain extra information about which file descriptor caused the event (`si_fd`) and what events happened on it (`si_band`). The logic around which FD is populated within `si_fd` matches Linux's, which means it has some weird edge cases where that value may not actually refer to a file descriptor that is still valid. This CL also ports extra S/R logic regarding async handler in VFS2. Without this, async I/O handlers aren't properly re-registered after S/R. PiperOrigin-RevId: 345436598
