Subcontainers are only configured when the container starts, however because
start doesn't load the spec, flag annotations that may override flags were
not getting applied to the configuration.

In case setting up network fails, log a warning and fallback to internal
network.

Gofer panics are suppressed by p9 server and an error
is returned to the caller, making it effectively the
same as returning EROFS.

This allows runsc flags to be set per sandbox instance. For
example, K8s pod annotations can be used to enable
--debug for a single pod, making troubleshoot much easier.
Similarly, features like --vfs2 can be enabled for
experimentation without affecting other pods in the node.

Also removes `--profile-goroutine` because it's equivalent
to `debug --stacks`.

- Combine process creation code that is shared between
root and subcontainer processes
- Move root container information into a struct for
clarity

Adds a netns flag to runsc spec that allows users to specify a network
namespace path when creating a sample config.json file. Also, adds the ability
to specify the command arguments used when running the container.
This will make it easier for new users to create sample OCI bundles without
having to edit the config.json by hand.

Previously, it was not possible to encode/decode an object graph which
contained a pointer to a field within another type. This was because the
encoder was previously unable to disambiguate a pointer to an object and a
pointer within the object.
This CL remedies this by constructing an address map tracking the full memory
range object occupy. The encoded Refvalue message has been extended to allow
references to children objects within another object. Because the encoding
process may learn about object structure over time, we cannot encode any
objects under the entire graph has been generated.
This CL also updates the state package to use standard interfaces intead of
reflection-based dispatch in order to improve performance overall. This
includes a custom wire protocol to significantly reduce the number of
allocations and take advantage of structure packing.
As part of these changes, there are a small number of minor changes in other
places of the code base:
* The lists used during encoding are changed to use intrusive lists with the
objectEncodeState directly, which required that the ilist Len() method is
updated to work properly with the ElementMapper mechanism.
* A bug is fixed in the list code wherein Remove() called on an element that is
already removed can corrupt the list (removing the element if there's only a
single element). Now the behavior is correct.
* Standard error wrapping is introduced.
* Compressio was updated to implement the new wire.Reader and wire.Writer
inteface methods directly. The lack of a ReadByte and WriteByte caused issues
not due to interface dispatch, but because underlying slices for a Read or
Write call through an interface would always escape to the heap!
* Statify has been updated to support the new APIs.
See README.md for a description of how the new mechanism works.

SetTraceback("all") does not include all goroutines in panics (you didn't think
it was that simple, did you?). It includes all _user_ goroutines; those started
by the runtime (such as GC workers) are excluded.
Switch to "system" to additionally include runtime goroutines, which are useful
to track down bugs in the runtime itself.

* Aggregate architecture Overview in "What is gVisor?" as it makes more sense
in one place.
* Drop "user-space kernel" and use "application kernel". The term "user-space
kernel" is confusing when some platform implementation do not run in
user-space (instead running in guest ring zero).
* Clear up the relationship between the Platform page in the user guide and the
Platform page in the architecture guide, and ensure they are cross-linked.
* Restore the call-to-action quick start link in the main page, and drop the
GitHub link (which also appears in the top-right).
* Improve image formatting by centering all doc and blog images, and move the
image captions to the alt text.

We can register any number of tables with any number of architectures, and
need not limit the definitions to the architecture in question. This allows
runsc to generate documentation for all architectures simultaneously.
Similarly, this simplifies the VFSv2 patching process.

Previously we unconditionally failed to cleanup the networking files
(hostname, resolve.conf, hosts), and failed to cleanup the netns, etc on
partial setup failure.
We can drop the iptables commands from cleanup, as the routes
automatically go away when the device is deleted. Those commands were
failing previously.
Forward signals to the container, allowing it to exit normally when a
signal is received, and then for runsc to run the cleanup. This doesn't
cover cleanup when runsc is signalled before the container start, it
covers the most common case.
Fixes #2539
Fixes #2540

This change adds a layer of abstraction around the internal Docker APIs,
and eliminates all direct dependencies on Dockerfiles in the infrastructure.
A subsequent change will automated the generation of local images (with
efficient caching). Note that this change drops the use of bazel container
rules, as that experiment does not seem to be viable.

This is to make easier to find corresponding logs in
