This const was previously living in pkg/signal, but with that package
being moved to its own module, it didn't make much sense to put docker's
defaults in a generic module.
The const from the "signal" package is currenlty used *both* by the CLI
and the daemon as a default value when creating containers. This put up
some questions:
a. should the default be non-exported, and private to the container
package? After all, it's a _default_ (so should be used if _NOT_ set).
b. should the client actually setting a default, or instead just omit
the value, unless specified by the user? having the client set a
default also means that the daemon cannot change the default value
because the client (or older clients) will override it.
c. consider defaults from the client and defaults of the daemon to be
separate things, and create a default const in the CLI.
This patch implements option "a" (option "b" will be done separately,
as it involves the CLI code). This still leaves "c" open as an option,
if the CLI wants to set its own default.
Unfortunately, this change means we'll have to drop the alias for the
deprecated pkg/signal.DefaultStopSignal const, but a comment was left
instead, which can assist consumers of the const to find why it's no
longer there (a search showed the Docker CLI as the only consumer though).

go1.16.7 (released 2021-08-05) includes a security fix to the net/http/httputil
package, as well as bug fixes to the compiler, the linker, the runtime, the go
command, and the net/http package. See the Go 1.16.7 milestone on the issue
tracker for details:

This makes sure that the value set in the daemon can be used as-is,
without having to replicate the normalization logic elsewhere.

This allows containers to use the embedded default profile if a different
default is set (e.g. "unconfined") in the daemon configuration. Without this
option, users would have to copy the default profile to a file in order to
use the default.

Commit b237189e6c implemented an option to
set the default seccomp profile in the daemon configuration. When that PR
was reviewed, it was discussed to have the option accept the path to a custom
profile JSON file; https://github.com/moby/moby/pull/26276#issuecomment-253546966
However, in the implementation, the special "unconfined" value was not taken into
account. The "unconfined" value is meant to disable seccomp (more factually:
run with an empty profile).
While it's likely possible to achieve this by creating a file with an an empty
(`{}`) profile, and passing the path to that file, it's inconsistent with the
`--security-opt seccomp=unconfined` option on `docker run` and `docker create`,
which is both confusing, and makes it harder to use (especially on Docker Desktop,
where there's no direct access to the VM's filesystem).
This patch adds the missing check for the special "unconfined" value.

Using "default" as a name is a bit ambiguous, because the _daemon_ default
can be changed using the '--seccomp-profile' daemon flag.

This function was added in a754d89b40, but not
used. Currently, the only consumer of this function I could find was docker/cli,
which used it in a unit-test (this test has already been updated to not depend
on this function); https://grep.app/search?q=.CustomHTTPHeaders%28%29&filter[lang][0]=Go
Given that commit a68ae4a2d9 deprecated the
corresponding client.SetCustomHTTPHeaders() function, and because there is no
active use for this function, it should be ok to deprecate.
We can include this in a patch-release (to be sure nobody else is depending on
it, and (if someone is) to notify them of the deprecation.
As a follow-up to this commit, I'll remove both functions.

The `CapabilityMapping` and `Capabilities` types appeared to be only
used locally, and added unneeded complexity.
This patch removes those types, and simplifies the logic to use a
map that maps names to `capability.Cap`s

A capability can either be invalid, or not supported by the kernel
on which we're running. This patch changes the error message produced
to reflect if the capability is invalid/unknown, or a known capability,
but not supported by the kernel version.
