Discover API optional for drivers to implement, but forgot to remove the
stubs from the Windows drivers, which didn't implement this API.

The "Capability" type defines DataScope and ConnectivityScope fields,
but their value was set from consts in the datastore package, which
required importing that package and its dependencies for the consts
only.
This patch:
- Moves the consts to a separate "scope" package
- Adds aliases for the consts in the datastore package.

Most drivers do not implement this, so detect if a driver implements
the discoverAPI, and remove the implementation from drivers that do
not support it.

Go 1.15.7 contained a security fix for CVE-2021-3115, which allowed arbitrary
code to be executed at build time when using cgo on Windows.
This issue was not limited to the go command itself, and could also affect binaries
that use `os.Command`, `os.LookPath`, etc.
From the related blogpost (https://blog.golang.org/path-security):
> Are your own programs affected?
>
> If you use exec.LookPath or exec.Command in your own programs, you only need to
> be concerned if you (or your users) run your program in a directory with untrusted
> contents. If so, then a subprocess could be started using an executable from dot
> instead of from a system directory. (Again, using an executable from dot happens
> always on Windows and only with uncommon PATH settings on Unix.)
>
> If you are concerned, then we’ve published the more restricted variant of os/exec
> as golang.org/x/sys/execabs. You can use it in your program by simply replacing
At time of the go1.15 release, the Go team considered changing the behavior of
`os.LookPath()` and `exec.LookPath()` to be a breaking change, and made the
behavior "opt-in" by providing the `golang.org/x/sys/execabs` package as a
replacement.
However, for the go1.19 release, this changed, and the default behavior of
`os.LookPath()` and `exec.LookPath()` was changed. From the release notes:
https://go.dev/doc/go1.19#os-exec-path
> Command and LookPath no longer allow results from a PATH search to be found
> relative to the current directory. This removes a common source of security
> problems but may also break existing programs that depend on using, say,
> exec.Command("prog") to run a binary named prog (or, on Windows, prog.exe)
> in the current directory. See the os/exec package documentation for information
> about how best to update such programs.
>
> On Windows, Command and LookPath now respect the NoDefaultCurrentDirectoryInExePath
> environment variable, making it possible to disable the default implicit search
> of “.” in PATH lookups on Windows systems.
A result of this change was that registering the daemon as a Windows service
no longer worked when done from within the directory of the binary itself:
C:\> cd "Program Files\Docker\Docker\resources"
C:\Program Files\Docker\Docker\resources> dockerd --register-service
exec: "dockerd": cannot run executable found relative to current directory
Note that using an absolute path would work around the issue:
C:\Program Files\Docker\Docker>resources\dockerd.exe --register-service
This patch changes `registerService()` to use `os.Executable()`, instead of
depending on `os.Args[0]` and `exec.LookPath()` for resolving the absolute
path of the binary.

IPv6 ipt rules are exactly the same as IPv4 rules, although both
protocol don't use the same networking model. This has bad consequences,
for instance: 1. the current v6 rules disallow Neighbor
Solication/Advertisement ; 2. multicast addresses can't be used ; 3.
link-local addresses are blocked too.
To solve this, this commit changes the following rules:
```
-A DOCKER-ISOLATION-STAGE-1 ! -s fdf1:a844:380c:b247::/64 -o br-21502e5b2c6c -j DROP
-A DOCKER-ISOLATION-STAGE-1 ! -d fdf1:a844:380c:b247::/64 -i br-21502e5b2c6c -j DROP
```
into:
```
-A DOCKER-ISOLATION-STAGE-1 ! -s fdf1:a844:380c:b247::/64 ! -i br-21502e5b2c6c -o br-21502e5b2c6c -j DROP
-A DOCKER-ISOLATION-STAGE-1 ! -d fdf1:a844:380c:b247::/64 -i br-21502e5b2c6c ! -o br-21502e5b2c6c -j DROP
```
These rules only limit the traffic ingressing/egressing the bridge, but
not traffic between veth on the same bridge.
Note that, the Kernel takes care of dropping invalid IPv6 packets, eg.
loopback spoofing, thus these rules don't need to be more specific.
Solve #45460.

Refactor GetContainerLayerSize to calculate unpacked image size only by
following the snapshot parent tree directly instead of following it by
using diff ids from image config.
This works even if the original manifest/config used to create that
container is no longer present in the content store.

Check for generic `errdefs.NotFound` rather than specific error helper
struct when checking if the error is caused by the image not being
present.
It still works for `ErrImageDoesNotExist` because it
implements the NotFound errdefs interface too.

Split the buildDetailedNetworkResources function into separate functions for

- Pass the endpoint and endpoint-info, instead of individual fields from the
endpoint.
- Remove redundant nil-check, as it's already checked on the call-side

Make the function return the constructed network.IPAM instead of applying
it to a network struct, and rename it to "buildIPAMResources".
Rewrite the function itself:
- Use struct-literals where possible to make it slightly more readable.
- Use a boolean (hasIPv4Config, hasIPv6Config) for both IPv4 and IPv6 to
check whether the IPAM-info needs to be added. This makes the logic the
same for both, and makes the processing order-independent. This also
allows for the `network.IpamInfo()` call to be skipped if it's not needed.
- Change order of "ipv4 config / ipv4 info" and "ipv6 config / ipv4 info"
blocks to make it slightly clearer (and to allow skipping the forementioned
call to `network.IpamInfo()`).

This variable was only accessed from within LocalRegistry methods, but
due to being a package-level variable, tests had to deal with setting
and resetting it.
Move it to be a field scoped to the LocalRegistry. This simplifies the
tests, and to make this more transparent, also removing the "Setup()"
helper (which, wasn't marked as a t.Helper()).

The client's transport can only be set by newClientWithTransport, which

However, requestFactory is mocked in one of the tests, so keep the interface,

The interface is not consumed anywhere, and only non-exported functions
produced one, so we can remove it.
