Add a symbolic link ("symlink") object support to Swift. This
object will reference another object. GET and HEAD
requests for a symlink object will operate on the referenced object.
DELETE and PUT requests for a symlink object will operate on the
symlink object, not the referenced object, and will delete or
overwrite it, respectively.
POST requests are *not* forwarded to the referenced object and should
be sent directly. POST requests sent to a symlink object will
result in a 307 Error.
Historical information on symlink design can be found here:

Make some json -> (text, xml) stuff in a common module, reference that in
account/container servers so we don't break existing clients (including
out-of-date proxies), but have the proxy controllers always force a json
listing.
This simplifies operations on listings (such as the ones already happening in
decrypter, or the ones planned for symlink and sharding) by only needing to
consider a single response type.
There is a downside of larger backend requests for text/plain listings, but
it seems like a net win?

Previously, if a container listing produced `subdir` elements
the decrypter would raise a KeyError.
Additionally, update the functests so this sort of thing would
have been caught at the gate.

Adds encryption middlewares.
All object servers and proxy servers should be upgraded before
introducing encryption middleware.
Encryption middleware should be first introduced with the
encryption middleware disable_encryption option set to True.
Once all proxies have encryption middleware installed this
option may be set to False (the default).
Increases constraints.py:MAX_HEADER_COUNT by 4 to allow for
headers generated by encryption-related middleware.
