functests fail with name_check middleware

[John Dickinson]

The name_check middleware (with default settings) constrains the maximum length of account+container+object to something that is normally much shorter than the limits allowed in swift.conf. The functests check against what's defined in swift.conf (or test.conf), so the name_check settings must be updated for these limit tests to pass.

Additionally, the default name_check settings prevent some characters from being sent in a request, and these characters are used in the TestAccount.testQuotedWWWAuthenticateHeader test, making the test fail.

Mitigation is to not have name_check in the pipeline when running functests.
