The FileDescription implementation for hostfs sockets uses the standard Unix
socket implementation (unix.SocketVFS2), but is also tied to a hostfs dentry.

Sentry metrics with nanoseconds units are labeled as such, and non-cumulative
sentry metrics are supported.

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.

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

Determine system time from within the sentry rather than relying on the remote
filesystem to prevent inconsistencies.
Resolve related TODOs; the time discrepancies in question don't exist anymore.

This required minor restructuring of how system call tables were saved
and restored, but it makes way more sense this way.

When copyUp fails, we attempt to clean up the upper filesystem by removing any
files that have already been copied-up. If the cleanup fails, we panic because
the "overlay filesystem is in an inconsistent state".
This CL adds the original copy-up error to the panic information, to hopefully
make it easier to track down how the overlay filesystem got into the
inconsistent state.

Using the host-defined file owner matches VFS1. It is more correct to use the
host-defined mode, since the cached value may become out of date. However,
kernfs.Inode.Mode() does not return an error--other filesystems on kernfs are
in-memory so retrieving mode should not fail. Therefore, if the host syscall
fails, we rely on a cached value instead.
Updates #1672.

Frozen was to lock down changes to the host filesystem
for hostFS. Now that hostFS is gone, it can be removed.

Refactor fs/host.TTYFileOperations so that the relevant functionality can be
shared with VFS2 (fsimpl/host.ttyFD).
Incorporate host.defaultFileFD into the default host.fileDescription. This way,
there is no need for a separate default_file.go. As in vfs1, the TTY file
implementation can be built on top of this default and override operations as
necessary (PRead/Read/PWrite/Write, Release, Ioctl).
Note that these changes still need to be plumbed into runsc, which refers to
imported TTYs in control/proc.go:ExecAsync.
Updates #1672.

- When setting up the virtual filesystem, mount a host.filesystem to contain
all files that need to be imported.
- Make read/preadv syscalls to the host in cases where preadv2 may not be
supported yet (likewise for writing).
- Make save/restore functions in kernel/kernel.go return early if vfs2 is
enabled.

- Make oomScoreAdj a ThreadGroup field (Linux: signal_struct::oom_score_adj).
- Avoid deadlock caused by Task.OOMScoreAdj()/SetOOMScoreAdj() locking Task.mu
and TaskSet.mu in the wrong order (via Task.ExitState()).
