ContinueOnError assumes that something of type errcode.Errors contains
at least one error. This is generally true, but might not be true if the
remote registry returns an empty error body or invalid JSON. Add the
bounds check, and in the case where it fails, allow fallbacks to v1.

This fix avoids overwritting the previous error messages, ensures the client gets the correct error messages and not just the most recent message during the pull request.
For this `var lastErr` replaced with a slice which acts as a temp place holder for the list of returned error messages for every attempt.
The slice is later joined and returned to the caller function after searching for the image with diffirent versions(v2,v1,v0).
Updated the code with check for no space left on device error occurance and prevent the
daemon on falling back to v1,v0.

This updates the vendored docker/distribution to the current master
branch.
Note the following changes:
- The manifest package was split into manifest/schema1. Most references
to the manifest package in the engine needed to be updated to use
schema1 instead.
- Validation functions in api/v2 were replaced by the
distribution/reference package. The engine code has been updated to
use the reference package for validation where necessary. A future PR
will change the engine to use the types defined in
distribution/reference more comprehensively.
- The reference package explicitly allows double _ characters in
repository names. registry_test.go was updated for this.
- TestPullFailsWithAlteredManifest was corrupting the manifest JSON, now
that the schema1 package unmarshals the correct payload. The test is
being changed to modify the JSON without affecting its length, which
allows the pull to succeed to the point where digest validation
happens.

Add a daemon flag to control this behaviour. Add a warning message when pulling
an image from a v1 registry. The default order of pull is slightly altered
with this changset.
Previously it was:
https v2, https v1, http v2, http v1
now it is:
https v2, http v2, https v1, http v1
Prevent login to v1 registries by explicitly setting the version before ping to
prevent fallback to v1.
Add unit tests for v2 only mode. Create a mock server that can register
handlers for various endpoints. Assert no v1 endpoints are hit with legacy
registries disabled for the following commands: pull, push, build, run and
login. Assert the opposite when legacy registries are not disabled.

Some structures use int for sizes and UNIX timestamps. On some
platforms, int is 32 bits, so this can lead to the year 2038 issues and
overflows when dealing with large containers or layers.
Consistently use int64 to store sizes and UNIX timestamps in
api/types/types.go. Update related to code accordingly (i.e.
strconv.FormatInt instead of strconv.Itoa).
Use int64 in progressreader package to avoid integer overflow when
dealing with large quantities. Update related code accordingly.

This patch fixes a bug where a user specifies a v1 mirror for
--registry-mirror and pull an image from the Hub.
It used to not fallback because of an unexpected error returned when
trying to JSON marshal nginx output.
We now ensure that any unexpected error falls back to the next endpoint
in the list.

Add a trusted flag to force the cli to resolve a tag into a digest via the notary trust library and pull by digest.
On push the flag the trust flag will indicate the digest and size of a manifest should be signed and push to a notary server.
If a tag is given, the cli will resolve the tag into a digest and pull by digest.
After pulling, if a tag is given the cli makes a request to tag the image.
Use certificate directory for notary requests
Read certificates using same logic used by daemon for registry requests.
Catch JSON syntax errors from Notary client
When an uncaught error occurs in Notary it may show up in Docker as a JSON syntax error, causing a confusing error message to the user.
Provide a generic error when a JSON syntax error occurs.
Catch expiration errors and wrap in additional context.

This patch creates a new cli package that allows to combine both client
and daemon commands (there is only one daemon command: docker daemon).
The `-d` and `--daemon` top-level flags are deprecated and a special
message is added to prompt the user to use `docker daemon`.
Providing top-level daemon-specific flags for client commands result
in an error message prompting the user to use `docker daemon`.
This patch does not break any old but correct usages.
This also makes `-d` and `--daemon` flags, as well as the `daemon`
command illegal in client-only binaries.
