Currently Docker authorization framework does not use any user
information, which already available in the Docker context for TLS
connection.
The purpose of this CR is to complete the existing authz work by adding
the basic client certificate details (SUBJECT_NAME) and authentication
method (TLS) to the authz request.
We think this should be the default behavior when no extended
authorization module is specified (currently WIP under #20883).

Changes how the Engine interacts with Registry servers on image pull.
Previously, Engine sent a User-Agent string to the Registry server
that included only the Engine's version information. This commit
appends to that string the fields from the User-Agent sent by the
client (e.g., Compose) of the Engine. This allows Registry server
operators to understand what tools are actually generating pulls on
their registries.

Prior to this change, the "docker network inspect" contains only the
endpoints that have active local container. This excludes all the remote
and stale endpoints. By including all the endpoints, it makes debugging
much simpler and also allows the user to cleanup any stale endpoints
using "docker network disconnect -f {network} {endpoint-name}".

Moving all strings to the errors package wasn't a good idea after all.
Our custom implementation of Go errors predates everything that's nice
and good about working with errors in Go. Take as an example what we
have to do to get an error message:
```go
func GetErrorMessage(err error) string {
switch err.(type) {
case errcode.Error:
e, _ := err.(errcode.Error)
return e.Message
case errcode.ErrorCode:
ec, _ := err.(errcode.ErrorCode)
return ec.Message()
default:
return err.Error()
}
}
```
This goes against every good practice for Go development. The language already provides a simple, intuitive and standard way to get error messages, that is calling the `Error()` method from an error. Reinventing the error interface is a mistake.
Our custom implementation also makes very hard to reason about errors, another nice thing about Go. I found several (>10) error declarations that we don't use anywhere. This is a clear sign about how little we know about the errors we return. I also found several error usages where the number of arguments was different than the parameters declared in the error, another clear example of how difficult is to reason about errors.
Moreover, our custom implementation didn't really make easier for people to return custom HTTP status code depending on the errors. Again, it's hard to reason about when to set custom codes and how. Take an example what we have to do to extract the message and status code from an error before returning a response from the API:
```go
switch err.(type) {
case errcode.ErrorCode:
daError, _ := err.(errcode.ErrorCode)
statusCode = daError.Descriptor().HTTPStatusCode
errMsg = daError.Message()
case errcode.Error:
// For reference, if you're looking for a particular error
// then you can do something like :
// import ( derr "github.com/docker/docker/errors" )
// if daError.ErrorCode() == derr.ErrorCodeNoSuchContainer { ... }
daError, _ := err.(errcode.Error)
statusCode = daError.ErrorCode().Descriptor().HTTPStatusCode
errMsg = daError.Message
default:
// This part of will be removed once we've
// converted everything over to use the errcode package
// FIXME: this is brittle and should not be necessary.
// If we need to differentiate between different possible error types,
// we should create appropriate error types with clearly defined meaning
errStr := strings.ToLower(err.Error())
for keyword, status := range map[string]int{
"not found": http.StatusNotFound,
"no such": http.StatusNotFound,
"bad parameter": http.StatusBadRequest,
"conflict": http.StatusConflict,
"impossible": http.StatusNotAcceptable,
"wrong login/password": http.StatusUnauthorized,
"hasn't been activated": http.StatusForbidden,
} {
if strings.Contains(errStr, keyword) {
statusCode = status
break
}
}
}
```
You can notice two things in that code:
1. We have to explain how errors work, because our implementation goes against how easy to use Go errors are.
2. At no moment we arrived to remove that `switch` statement that was the original reason to use our custom implementation.
This change removes all our status errors from the errors package and puts them back in their specific contexts.
IT puts the messages back with their contexts. That way, we know right away when errors used and how to generate their messages.
It uses custom interfaces to reason about errors. Errors that need to response with a custom status code MUST implementent this simple interface:
```go
type errorWithStatus interface {
HTTPErrorStatusCode() int
}
```
This interface is very straightforward to implement. It also preserves Go errors real behavior, getting the message is as simple as using the `Error()` method.
I included helper functions to generate errors that use custom status code in `errors/errors.go`.
By doing this, we remove the hard dependency we have eeverywhere to our custom errors package. Yes, you can use it as a helper to generate error, but it's still very easy to generate errors without it.

Ideally I would love to just remove this check entirely because its
seems pretty useless. An old client talking to a new server isn't
an error condition, nor is it something to even worry about - its a normal
part of life. Flooding my screen (and logs) with a warning that isn't
something I (as an admin) need to be concerned about is silly and a
distraction when I need to look for real issues. If anything this should
be printed on the cli not the daemon since its the cli that needs to be
concerned, not the daemon.
However, since when you debug an issue it might be interesting to know the
client is old I decided to pull back a little and just change it from
a Warning to a Debug logrus call instead.
If others want it removed I still do that though :-)

Currently, daemonbuilder package (part of daemon) implemented the
builder backend. However, it was a very thin wrapper around daemon
methods and caused an implementation dependency for api/server build
endpoint. api/server buildrouter should only know about the backend
implementing the /build API endpoint.
Removing daemonbuilder involved moving build specific methods to

Currently builder.Backend is implemented by daemonbuilder.Docker{} for
the daemon. This registration happens in the API/server code. However,
this is too implementation specific. Ideally we should be able to specify
that docker daemon (or any other) is implementing the Backend and abstract
the implementation details. So we should remove package daemonbuilder
dependency in build_routes.go
With this change, daemonbuilder.Docker is nothing more than the daemon.
A follow on change will remove the daemonbuilder package and move relevant
methods under daemon, so that API only knows about the backend.
Also cleanup code in api/client/build.go. docker cli always performs build
context tar download for remoteURLs and sends an empty remoteContext. So
remove relevant dead code.

Makes `docker volume ls` and `docker volume inspect` ask the volume
drivers rather than only using what is cached locally.
Previously in order to use a volume from an external driver, one would
either have to use `docker volume create` or have a container that is
already using that volume for it to be visible to the other volume
API's.
For keeping uniqueness of volume names in the daemon, names are bound to
a driver on a first come first serve basis. If two drivers have a volume
with the same name, the first one is chosen, and a warning is logged
about the second one.
Adds 2 new methods to the plugin API, `List` and `Get`.
If a plugin does not implement these endpoints, a user will not be able
to find the specified volumes as well requests go through the drivers.

Right now, the quiet (-q, --quiet) flag ignores the output
generated from within the container.
However, it ought to be quiet in a way that all kind
of diagnostic output should be ignored, unless the build
process fails.
This patch makes the quiet flag behave in the following way:
1. If the build process succeeds, stdout contains the image ID
and stderr is empty.
2. If the build process fails, stdout is empty and stderr
has the error message and the diagnostic output of that process.
If the quiet flag is not set, then everything goes to stdout
and error messages, if there are any, go to stderr.
