This is the third step of migrating to the new format: removing support
for the legacy format.

This is the second step of migrating to our new XSRF token format. The
first step ([] made validate() start accepting new tokens
(basically, dual-read). This step cuts over our "writing" to write the
new token format. The third and final step will drop support for
validating the old token format (back to single-read). We'll do that
in a subsequent push so that we don't invalidate all the current XSRF
tokens that people might have in their browsers.

This follows up on Brian's work to transition not just to a new format
with an empty scope value, but instead to replace the existing format
entirely with a new one that:
1) includes a version number to support future format migrations
2) doesn't include a field for the scope at all, since scoping the
tokens adds no real security benefit and just makes verification
more difficult
3) replaces the raw SHA-256 hash with a SHA-256 HMAC instead, as a
best practice to avoid length-extension attacks [1], even though
in our particular case they would only be able to extend the
timestamp and would thus be relatively innocuous
The new format will be produced by calling generateToken(), and the
scope-accepting version is renamed to generateLegacyToken() in addition
to its existing deprecation, for maximum clarity.
I changed the validateToken() logic to stop accepting a scope entirely;
when validating a legacy-style token, we'll test it against the two
existing legacy scope values ("admin" and "console") and accept it if
it matches either one.
Note that this means the xsrfScope parameter in @Action is now wholly
obsolete; I'll remove it in a follow-up to avoid bringing extra files
into this CL.
After this CL hits production, the next one will replace all calls to
generateLegacyToken() with generateToken(). Once that CL is deployed,
the last step will be removing the legacy fallback in validateToken().

I'm working on some changes to XsrfTokenManager (b/35388772) and ServerSecret
was crufty enough that I ended up rewriting it. Now it uses a LoadingCache
with a transaction instead of needlessly race-condition-y static init logic.
It also now supports retrieving its value as either a UUID (the old format
used by XsrfTokenManager) or a byte[]. The latter is more flexible and can
be directly used with HMAC which the new XsrfTokenManager format will employ.
And lastly, I added tests. In addition, I tested this code on alpha and
verified appropriate operation (XSRF tokens still work from the console and
from regtool; if you remove ServerSecret from datastore and memcache, it
persists a new one).

The one-day validity period is also moved from the caller into XsrfTokenManager.

This adds XSRF tokens so that the epptool request succeeds, adds better logging for debugging load test requests, adds better validation, and improves documentation.

The dark lord Gosling designed the Java package naming system so that
ownership flows from the DNS system. Since we own the domain name
registry.google, it seems only appropriate that we should use
google.registry as our package name.
This change renames directories in preparation for the great package
rename. The repository is now in a broken state because the code
itself hasn't been updated. However this should ensure that git
correctly preserves history for each file.
