jshint: Allow global mw to be set in mediawiki.js

In master this has been cleaned up, but in REL1_20 we still used
the 'mw' global directly in a bunch of placed so we need to tell
jshint that it is okay for it to be set in mediawiki.js

It is currently complaining about redefinition because of this.

Make wfSuppressWarnings kill E_STRICT in PHP 5.4+

Since PHP 5.4+ E_STRICT is now included in E_ALL. Hence
wfSuppressWarnings was not filtering E_STRICT.

There was some complaints on project:support_desk about
timezone warnings popping up. See also bug 43092

Release notes for wfSuppressWarnings change I backported to 1.20

See gerrit change 44165. I did the same thing for 1.19, since
no one told me I did it wrong (yay!) now doing it for 1.20.

Using separate commit for release notes in order to use
cherry-pick for the actual commit. Have no idea if that is
important or not.

(bug 31044) Make ResourceLoader behave in read-only mode

When the database is in read-only mode or writes fail for some other
reason, ResourceLoader should make every attempt to still serve JS and
CSS correctly.

* Surround a bunch of DB write code in MessageBlobStore.php in try-catch
  blocks.
* Surround the DB write in ResourceLoaderFileModule.php in a try-catch
  block rather than checking wfReadOnly(), because the DB may fail for
  other reasons.
* In ResourceLoader::respond() and helpers, set a short cache timeout on
  responses that include commented-out error messages.
