registry/{storage,handlers}: limit content sizes
Under certain circumstances, the use of `StorageDriver.GetContent` can
result in unbounded memory allocations. In particualr, this happens when
accessing a layer through the manifests endpoint.

This problem is mitigated by setting a 4MB limit when using to access
content that may have been accepted from a user. In practice, this means
setting the limit with the use of `BlobProvider.Get` by wrapping
`StorageDriver.GetContent` in a helper that uses `StorageDriver.Reader`
with a `limitReader` that returns an error.

When mitigating this security issue, we also noticed that the size of
manifests uploaded to the registry is also unlimited. We apply similar
logic to the request body of payloads that are full buffered.

2aa09ff9a8 registry/storage: more efficient path compare in catalog
Previous component-wise path comparison is recursive and generates a
large amount of garbage. This more efficient version simply replaces the
path comparison with the zero-value to sort before everything. We do
this by replacing the byte-wise comparison that swaps a single character
inline for the separator comparison, such that separators sort first.

The resulting implementation provides component-wise path comparison
with no cost incurred for allocation or stack frame.

Direction of the comparison is also reversed to match Go style.

8907f7d189 Update "Accept" header parsing for list values
In Go's header parsing, the same header multiple times results in multiple entries in the `r.Header[...]` slice, but Go does no further parsing beyond that (and in https://golang.org/cl/4528086 it was determined that until/unless the stdlib itself needs it, Go will not do so).

The consequence here for parsing of `Accept:` headers is that we support the way Go outputs headers, but not all language HTTP libraries have a facility to output multiple headers instead of a single list header.

This change ensures that the following (valid) header blocks all parse to the same result for the purposes of what is being tested here:

```
Accept: a/b
Accept: b/c
Accept: d/e
```

```
Accept: a/b; q=0.5, b/c
Accept: d/e
```

```
Accept: a/b; q=0.1, b/c; q=0.2, d/e; q=0.8
```

33c448f147 Implement regulator in filesystem driver
This commit refactors base.regulator into the 2.4 interfaces and adds a
filesystem configuration option `maxthreads` to configure the regulator.

By default `maxthreads` is set to 100. This means the FS driver is
limited to 100 concurrent blocking file operations. Any subsequent
operations will block in Go until previous filesystem operations
complete.

This ensures that the registry can never open thousands of simultaneous
threads from os filesystem operations.

Note that `maxthreads` can never be less than 25.

Add test case covering parsable string maxthreads
