While reading from the input in WriteStream, the inmemory driver can deadlock
if the reader is from the same instance. To fix this, the write lock is
released before reading into a local buffer. The lock is re-acquired to
finish the actual write.

This changeset implements a fileWriter type that can be used to managed writes
to remote files in a StorageDriver. Basically, it manages a local seek position
for a remote path. An efficient use of this implementation will write data in
large blocks.

We now also have a storagedriver error variable for identifying
api calls that are not implemented by drivers (the URLFor method
is not implemented by either the filesystem or inmemory drivers)
No longer requires that file paths match the repository naming scheme,
but instead allows path components as short as a single character, as to
accommodate for single-character tag names.
When adding parameters to a location header, the client must not destroy
parameters already present. This change ensures that parameters are added,
rather than replaced when assembling the url.

Since the repo is no longer just the registry, we are moving the registry web
application package out of the repo root into a sub-package. We may break down
the registry package further to separate webapp components and bring the client
package under it. This change accomplishes the task of freeing up the repo root
for a distribution-oriented package. A stub doc.go file is left in place to
declare intent.

The exported StringSet type is not necessary for the current use case of
validating issues and audiences. The exported fields on VerifyOptions have been
changed to require string slices. The collections package has been removed and
the StringSet has been moved to the token package, where it is used.

Since the common package no longer exists, the testutil package is being moved
up to the root. Ideally, we don't have large omnibus packages, like testutil,
but we can fix that in another refactoring round.

Because the repository name definitions are part of the v2 specification, they
have been moved out of the common package. This is part of the effort to break
up the common package into more sensible components.

In preparation for removing the common package, the tarsum utilities are being
moved to the more relevant digest package. This functionality will probably go
away in the future, but it's maintained here for the time being.

As part of the efforts to break up the common package before disaster strikes,
a new collections package has been created. More may belong there but for now,
it only includes an implementation of StringSet.

Note that the README currently contains details about the secure parameter which is part of a
separate pull request. I feel confident adding it here since I am certain we will eventually add
the secure parameter. Also note that encrypt now defaults to true and rootdirectory defaults to
the empty string.
To support clustered registry, upload UUIDs must be recognizable by
registries that did not issue the UUID. By creating an HMAC verifiable
upload state token, registries can validate upload requests that other
instances authorized. The tokenProvider interface could also use a redis
store or other system for token handling in the future.
It was probably ill-advised to couple manifest signing and verification to
their respective types. This changeset simply changes them from methods to
functions. These might not even be in this package in the future.

Because manifests and their signatures are a discrete component of the
registry, we are moving the definitions into a separate package. This causes us
to lose some test coverage, but we can fill this in shortly. No changes have
been made to the external interfaces, but they are likely to come.

Many details have been updated in route descriptors. This commit regenerates
the specification from the latest changes and template.
Signed-off-by: Stephen J Day <stephen.day@docker.com>
This changeset fills in details for many RouteDescriptors, ensuring that
responses and their variation are fully covered. At this point, all endpoints
are described in full. Tweaks for consistency and to avoid repetition may still
need to be done.
