This change also switches lock EOF to be MaxInt instead of MaxUint,
since the lock length can be a negative value.

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.

- Support FIOASYNC, FIO{SET,GET}OWN, SIOC{G,S}PGRP (refactor getting/setting
owner in the process).
- Unset signal recipient when setting owner with pid == 0 and
valid owner type.

This includes the provisional style guide in the website and fixes the broken
link from CONTRIBUTING.md. The style guide will be located under the "Community"
category as it's related to contributing to the project.
Also, add missing includes that were causing some presubmits to fail.

- Change FileDescriptionImpl Lock/UnlockPOSIX signature to
take {start,length,whence}, so the correct offset can be
calculated in the implementations.
- Create PosixLocker interface to make it possible to share
the same locking code from different implementations.

absl flags are more modern and we can easily depend on them directly.
The repo now successfully builds with --incompatible_load_cc_rules_from_bzl.
