Updated how restoring occurs through boot.go with a separate Restore function.
This prevents a new process and new mounts from being created.
Added tests to ensure the container is restored.
Registered checkpoint and restore commands so they can be used.
Docker support for these commands is still limited.
Working on #80.

The leave-running flag allows the container to continue running after a
checkpoint has occurred by doing an immediate restore into a new
container with the same container ID after the old container is destroyed.
Updates #80.

There is a subtle bug where during cleanup with unread data a FIN can
be converted to a RST, at that point the entire connection should be
aborted as we're not expecting any ACKs to the RST.

Users can now call "runsc wait <container id>" to wait on a particular process
inside the container. -pid can also be used to wait on a specific PID.
Manually tested the wait subcommand for a single waiter and multiple waiters
(simultaneously 2 processes waiting on the container and 2 processes waiting on
a PID within the container).

CheckIORange is analagous to Linux's access_ok() method, which is checked when
copying in IOVecs in both lib/iov_iter.c:import_single_range() and
lib/iov_iter.c:import_iovec() => fs/read_write.c:rw_copy_check_uvector().
gVisor copies in IOVecs via Task.SingleIOSequence() and Task.CopyInIovecs().
We were checking the address range bounds, but not whether the address is
valid. To conform with linux, we should also check that the address is valid.
For usual preadv/pwritev syscalls, the effect of this change is not noticeable,
since we find out that the address is invalid before the syscall completes.
For vectorized async-IO operations, however, this change is necessary because
Linux returns EFAULT when the operation is submitted, but before it executes.
Thus, we must validate the iovecs when copying them in.

Now able to save the state file (checkpoint.img) at an image-path that had
previously not existed. This is important because there can only be one
checkpoint.img file per directory so this will enable users to create as many
directories as needed for proper organization.

If the child stubs are killed by any unmaskable signal (e.g. SIGKILL), then
the parent process will similarly be killed, resulting in the death of all
other stubs.
The effect of this is that if the OOM killer selects and kills a stub, the
effect is the same as though the OOM killer selected and killed the sentry.

IsChrooted still has the opportunity to race with another thread
entering the FSContext into a chroot, but that is unchanged (and
fine, AFAIK).

The interfaces and their addresses are already available via
the stack Intefaces and InterfaceAddrs.
Also add some tests as we had no tests around SIOCGIFCONF. I also added the socket_netgofer lifecycle for IOCTL tests.

The shutdown behavior where we return EAGAIN for sockets
which are non-blocking is only correct for packet based sockets.
SOCK_STREAM sockets should return EOF.

Added a number of unimplemented flags required for using runsc's
Checkpoint and Restore with Docker. Modified the "image-path" flag to
require a directory instead of a file.

SIGUSR2 was being masked out to be used as a way to dump sentry
stacks. This could cause compatibility problems in cases anyone
uses SIGUSR2 to communicate with the container init process.

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.

Before a container can be restored, the mounts must be configured.
The root and submounts and their key information is compiled into a
RestoreEnvironment.
Future code will be added to set this created environment before
restoring a container.
Tests to ensure the correct environment were added.

Restore creates a new container and uses the given image-path to load a saved
image of a previous container. Restore command is plumbed through container
and sandbox. This command does not work yet - more to come.

that many more options will be added in the future.
