- Redocument memory ordering from "no ordering" to "acquire-release". (No
functional change: both LOCK WHATEVER on x86, and LDAXR/STLXR loops on ARM64,
already have this property.)
- Remove IncUnlessZeroInt32 and DecUnlessOneInt32, which were only faster than
the equivalent loops using sync/atomic before the Go compiler inlined
non-unsafe.Pointer atomics many releases ago.

glibc defines struct epoll_event in such a way that epoll_event.data.fd exists.
However, the kernel's definition of struct epoll_event makes epoll_event.data
an opaque uint64, so naming half of it "fd" just introduces confusion. Remove
the Fd field, and make Data a [2]int32 to compensate.
Also add required padding to linux.EpollEvent on ARM64.

This is to fix a data race between sending an external signal to
a ThreadGroup and kernel saving state for S/R.

This is easier than storing errors from e.g. CopyOut in the callback.

These are not used outside of the p9 package.

This requires fixing a few build issues for non-am64 platforms.

- Added fsbridge package with interface that can be used to open
and read from VFS1 and VFS2 files.
- Converted ELF loader to use fsbridge
- Added VFS2 types to FSContext
- Added vfs.MountNamespace to ThreadGroup

- Add missing build tags to files in the abi package.
- Add the marshal package as a sentry dependency, allowed by deps_test.
- Fix an issue with our top-level go_library BUILD rule, which
incorrectly shadows the variable containing the input set of source
files. This caused the expansion for the go_marshal clause to
silently omit input files.
- Fix formatting when copying build tags to gomarshal-generated files.
- Fix a bug with import statement collision detection in go-marshal.

This allow callers to say whether the file is being
opened to be executed, so that the proper checks can
be done from FilesystemImpl.OpenAt()

- Adds creation of user chains via `-N <chainname>`
- Adds `-j RETURN` support for built-in chains, which triggers the
chain's underflow rule (usually the default policy).
- Adds tests for chain creation, default policies, and `-j RETURN' from
built-in chains.

Fixes #1812. (The more direct cause of the deadlock is panic unsafety because
the historically high cost of defer means that we avoid it in hot paths,
including much of MM; defer is much cheaper as of Go 1.14, but still a
measurable overhead.)

The slaveInodeOperations is currently copying the object when
truncate is called (which is a no-op). This may result in a
(unconsequential) data race when being modified concurrently.

Put most of the logic for getxattr in one place for clarity. This simplifies
FGetXattr and getXattrFromPath, which are just wrappers for getXattr.
