Implement ioctl(FIOASYNC) FIOASYNC and friends are used to send signals when a file is ready for IO. This may or may not be needed by Nginx. While Nginx does use it, it is unclear if the code that uses it has any effect. PiperOrigin-RevId: 201550828 Change-Id: I7ba05a7db4eb2dfffde11e9bd9a35b65b98d7f50

Implement `fcntl` options `F_GETSIG` and `F_SETSIG`. 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

Port GETOWN, SETOWN fcntls to vfs2. Also make some fixes to vfs1's F_SETOWN. The fcntl test now entirely passes on vfs2. Fixes #2920. PiperOrigin-RevId: 318669529

New sync package. * Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387
