Several tests are passing after getting TestAppExitStatus (run /bin/true)
changes. Make versions that run via VFS2 so that we know what is and isn't
working.
In addition, fix bug in VFSFile ReadFull. For the TestExePath test in
container_test.go, the case "unmasked" will return 0 bytes read with no
EOF err, causing the ReadFull call to spin.

Ran a packetimpact test after `docker image rm` and examined the message.

This change includes:
- Modifications to loader_test.go to get TestCreateMountNamespace to
pass with VFS2.
- Changes necessary to get TestHelloWorld in image tests to pass with
VFS2. This means runsc can run the hello-world container with docker
on VSF2.
Note: Containers that use sockets will not run with these changes.
See "//test/image/...". Any tests here with sockets currently fail
(which is all of them but HelloWorld).

When run on Linux, a correct ICMPv6 response is received. On netstack, no
ICMPv6 response is received.

This change moves all Docker images to a standard location, and abstracts the
build process so that they can be maintained in an automated fashion. This also
allows the images to be architecture-independent.
All images will now be referred to by the test framework via the canonical
`gvisor.dev/images/<name>`, where `<name>` is a function of the path within the
source tree.
In a subsequent change, continuous integration will be added so that the images
will always be correct and available locally.
In the end, using `bazel` for Docker containers is simply not possible. Given
that we already have the need to use `make` with the base container (for
Docker), we extend this approach to get more flexibility.
This change also adds a self-documenting and powerful Makefile that is intended
to replace the collection of scripts in scripts. Canonical (self-documenting)
targets can be added here for targets that understand which images need to be
loaded and/or built.

A CancellableTimer's AfterFunc timer instance creates a closure over the
CancellableTimer's address. This closure makes a CancellableTimer unsafe
to copy.
No behaviour change, existing tests pass.

- Return ENOENT for /proc/[pid]/task if task is zoombied or terminated
- Allow directory to be Seek() to the end
- Construct synthetic files for /proc/[pid]/ns/*
- Changed GenericDirectoryFD.Init to not register with FileDescription,
otherwise other implementation cannot change behavior.

This is needed to set up host fds passed through a Unix socket. Note that
the host package depends on kernel, so we cannot set up the hostfs mount
directly in Kernel.Init as we do for sockfs and pipefs.
Also, adjust sockfs to make its setup look more like hostfs's and pipefs's.

Just call syscall.Fstat directly each time mode/file owner are needed. This
feels more natural than using i.getPermissions().

These methods let users eaily break the VectorisedView abstraction, and
allowed netstack to slip into pseudo-enforcement of the "all headers are
in the first View" invariant. Removing them and replacing with PullUp(n)
breaks this reliance and will make it easier to add iptables support and
rework network buffer management.
The new View.PullUp(n) method is low cost in the common case, when when
all the headers fit in the first View.

Ensure we use the correct architecture-specific defintion of epoll

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 just provides some sane reminders and ticks a box on the GitHub UI. This
change also cleans up the issue template, as there is already an automatic
link to the repository's security disclosure policy.

Even though BoundEndpointAt is not yet implemented for gofer fs, allow path
resolution errors to be returned so that we can jump to tmpfs, where it is
implemented.

This allows us to specify a richer configuration for the issue template, that
effectively moves a lot of the "metadata" from the template itself to the main
issue page.

bazel run :benchmarks only works from the benchmarks directory.
bazel run //benchmarks works from anywhere in the workspace.
Also fix help commands, which should be a multiline code section.

This change:
- Drastically simplifies the synchronization model: filesystem structure is
both implementation-defined and implementation-synchronized.
- Allows implementations of vfs.DentryImpl to use implementation-specific
dentry types, reducing casts during path traversal.
- Doesn't require dentries representing non-directory files to waste space on a
map of children.
- Allows dentry revalidation and mount lookup to be correctly ordered (fixed
FIXME in fsimpl/gofer/filesystem.go).
- Removes the need to have two separate maps in gofer.dentry
(dentry.vfsd.children and dentry.negativeChildren) for positive and negative
lookups respectively.
