go1.6 does. Fix this by hardcoding the status code for now.

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

When a blob upload is cancelled close the blobwriter before removing
upload state to ensure old hashstates don't persist.

It's easily possible for a flood of requests to trigger thousands of
concurrent file accesses on the storage driver. Each file I/O call creates
a new OS thread that is not reaped by the Golang runtime. By limiting it
to only 100 at a time we can effectively bound the number of OS threads
in use by the storage driver.

Use sockets.DialerFromEnvironment, as is done in other places,
to transparently support SOCKS proxy config from ALL_PROXY
environment variable.
Requires the *engine* have the ALL_PROXY env var set, which
doesn't seem ideal. Maybe it should be a CLI option somehow?
Only tested with push and a v2 registry so far. I'm happy to look
further into testing more broadly, but I wanted to get feedback on
the general idea first.

This fix tries to address the issue in #22244 where the remote
API `/auth` will not set the default value of `serveraddress`
if not provided. This behavior happens after only in 1.11.0
and is a regression as in 1.10.3 `serveraddress` will be assigned
with `IndexServer` if no value is provided.
The default value `IndexServer` is assigned to `serveraddress` if
no value provided in this fix.
An integration test `TestAuthApi` has been added to cover this change
This fix fixes#22244.

Not just when Commit()ing the result. This fixes some errors I observed
when the layer (i.e. the DLO) is Stat()ed immediately after closing,
and reports the wrong file size because the container listing is not
yet up-to-date.
