CVE-2013-0156: Safe XML params parsing. Doesn't allow symbols or yaml.
bumping version
Remove test for XML YAML parsing

The support for YAML parsing in XML has been removed from Active Support
since it introduced an security risk. See a494824 for more detail.

Remove test for XML YAML parsing
Methods that return nil should not be considered YAML

This is a direct port of @jaw6's pull request
https://github.com/rails/rails/pull/492. His cleanly applied to Rails
v3.1 and v3.2, and this cleanly applies to v3.0.

With yesterday's security patches
http://weblog.rubyonrails.org/2013/1/8/Rails-3-2-11-3-1-10-3-0-19-and-2-3-15-have-been-released/
there is now an issue with Rails v3.0 serving XML to any of the latest
versions of ActiveResource.

Without this, Rails v3.0 can serve XML to ActiveResource consumers that
will see `Hash::DisallowedType: Disallowed type attribute: "yaml"`

Merge pull request #8890 from dylanahsmith/3-0-parse-non-object-json-params

3-0-stable: Fix JSON params parsing regression for non-object JSON content.
Remove unnecessary caching of ParameterFilter
Fix 3-0-stable to work with Mocha >= v0.13.0

A) Update code in ActiveSupport which monkey-patches Test::Unit to
include Mocha bug fix.

A bug was fixed [1] in Mocha's integration with Test::Unit, but this
monkey-patching code was copied before the fix. We need to copy the
fixed version.

The bug meant that an unexpected invocation against a mock within the
teardown method caused a test *error* and not a test *failure*.

B) Fix for Test::Unit/Mocha compatibility.

Mocha is now using a single AssertionCounter which needs a reference to
the testcase as opposed to the result.

This change is an unfortunate consequence of the copying of a chunk of
Mocha's internal code in order to monkey-patch Test::Unit.

C) Avoid a Mocha deprecation warning.
