Rename requires files to standard names.

Rename tools/pip-requires to requirements.txt and tools/test-requires
to test-requirements.txt. These are standard files, and tools in the
general world are growing intelligence about them.

Fixes: bug #1179008
Fix faked-out account GET for JSON and XML.

If account autocreation is on and the proxy receives a GET request for
a nonexistent account, it'll fake up a response that makes it look as
if the account exists, but without reifying that account into sqlite
DB files.

That faked-out response was just fine as long as you wanted a
text/plain response, but it didn't handle the case of format=json or
format=xml; in those cases, the response would still be
text/plain. This can break clients, and certainly causes crashes in
swift3. Now, those responses match as closely as possible.

The code for generating an account-listing response has been pulled
into (the new) swift.account.utils module, and both the fake response
and the real response use it, thus ensuring that they can't
accidentally diverge. There's also a new probe test for that
non-divergence.

Also, cleaned up a redundant matching of the Accept header in the code
for generating the account listing.

Note that some of the added tests here pass with or without this code
change; they were added because the code I was changing (parts of the
real account GET) wasn't covered by tests.

Add requirements files to the source distribution

Also remove the tools directory, since it is no longer used, now that
https://review.openstack.org/30887 is merged, which renamed the
requirements files to requirements.txt and test-requirements.txt.

Change to use dash instead of slash

There is no known way to embed slashes into container names, even when
using URL escape sequences. Since it would seem that the more common
case would be some other character, we validate using a dash ('-')
character as the delimiter.

It should also be noted that the documentation for container listing,
found here:
http://docs.openstack.org/api/openstack-object-storage/1.0/content/s_listcontainers.html,
does not describe the use of the prefix or delimiter parameters.
