prlimit was erroneously comparing UIDs and GIDs when getting/setting a process'
own limits. From the manpage:
To set or get the resources of a process other than itself, the caller must have
the CAP_SYS_RESOURCE capability, or the real, effective, and saved set user IDs
of the target process must match the real user ID of the caller and the real,
effective, and saved set group IDs of the target process must match the real
group ID of the caller.

Included:
- loader_test.go RunTest and TestStartSignal VFS2
- container_test.go TestAppExitStatus on VFS2
- experimental flag added to runsc to turn on VFS2
Note: shared mounts are not yet supported.

This previously changed in 305699233, but this behaviour turned out to
be load bearing.

- Use the fs.File, rather than the vfs.FileDescription, in the VFS1 version.
- Check for a nil fs.File/vfs.FileDescription before calling DecRef, which is
possible if a racing dup2() or dup3() replaces the file descriptor between
when it is installed and when it is returned. (This is not possible in Linux
because Linux separates allocation of a file descriptor from binding an
allocated file descriptor to a struct file, and dup2/dup3 return EBUSY if
asked to replace an allocated but unbound file descriptor.)

Needed for PipeTest_Flags: files opened by open() and openat() get O_LARGEFILE
(on architectures with 64-bit off_t), but not FDs created by other syscalls
such as pipe().

Note that most kinds of sockets are not yet supported in VFS2
(only Unix sockets are partially supported at the moment), so
these syscalls will still generally fail. Enabling them allows
us to begin running socket tests for VFS2 as more features are
ported over.
Updates #1476, #1478, #1484, #1485.

The comments in the ticket indicate that this behavior
is fine and that the ticket should be closed, so we shouldn't
need pointers to the ticket.

noNewPrivileges is ignored if set to false since gVisor assumes that
PR_SET_NO_NEW_PRIVS is always enabled.

As in VFS1, we only support the user.* namespace. Plumbing is added to tmpfs
and goferfs.
Note that because of the slightly different order of checks between VFS2 and
Linux, one of the xattr tests needs to be relaxed slightly.
Fixes #2363.

The sentry doesn't allow execve, but it's a good defense
in-depth measure.

The dependency strace=>kernel grew over time. strace also depends on
task's FD table and FSContext. It could be fixed with some interfaces
the other way, but then we're trading an interface for another, and
kernel.Stracer is likely cleaner.
Closes #155

Block and drain requests in io_destroy(2).
Note the reason to create read-only mapping.
