Instead, use a thread-safe way. Current code using it is not threaded, but
future code will be.

Current tests have no extra dependencies.
This takes some time before running caucase tests, especially on slower
machines.

To accommodate with slower machines, which are a reasonable target for
caucase.
Caucase tests do not timeout anymore on a Raspberry Pi B+.

Allows running tests without setup.py around.

Remove special handling of first folder level.
Generalise CAU/CAS context decision.
Split functionalities further, making each method shorter.
Factorise subpath checks.
Factorise response generation when producing a body.

The resulting data structure, if more verbose than the original one, is
not harder to traverse and more extensible.

Chunk size is not bounded. So instead of remembering chunk tail, remember
how much there is to read in current chunk.

As per WSGI specs, transfer encoding (and other hop-by-hop headers) must
not be processed by WSGI applications.

Allows introducing more reasons to reject authentication, with different
WWW-Authenticate values.

So "wsgi.url_scheme" gets the correct value.

Needed by curl with --upload-file .
Curl also asks us to return "100 Continue" responses, but WSGI (as of
python 2.7 reference implementation) does not allow that. Gah.

So that wsgi layer can convert it into a 4xx error, and it stops being a
5xx error + traceback.
Add a test.

Allows enforcing CRL signature checking.

Actually access direct superclass. Too bad base class is not a new-style
class...

Prepares for CORS headers auto-generation.

So browsers accept to talk to me.

So tests ran on an older system fail with a clean error.
