API: Work around wfMangleFlashPolicy()
The things wfMangleFlashPolicy() does to the output break things in the
API. For JSON we can work around it, while for PHP we just have to error
out. XML isn't affected because <> are escaped anyway (unless something
somehow uses 'cross-domain-policy' as a tag name), and the rest are
going away soon so they're not worth the trouble.
Bug: 66776

* If the user has the 'deletedhistory' right, action=query's revids parameter
will now recognize deleted revids.
* prop=revisions may be used as a generator, generating revids.
+* (bug 66776) format=json results will no longer be corrupted when
+ $wgMangleFlashPolicy is in effect. format=php results will cleanly return an
+ error instead of returning invalid serialized data.
=== Action API internal changes in 1.25 ===
* ApiHelp has been rewritten to support i18n and paginated HTML output.
