Avoid internal error tracebacks on failure to lock on readonly transport (#129701).

Add new LockFailed, which doesn't imply that we failed to get it because of
contention.  Raise this if we fail to create the pending or lock directories
because of Transport errors.

UnlockableTransport is not an internal error.

ReadOnlyLockError has a message which didn't match its name or usage; it's now
deprecated and callers are updated to use LockFailed which is more appropriate.

Add zero_ninetytwo deprecation symbol.

Unify assertMatchesRe with TestCase.assertContainsRe.

When the constructor is deprecated, just say that the class is deprecated, not
the __init__ method - this works better with applyDeprecated in tests.
