* Use time() instead of:
- wfTimestamp()
- wfTimestamp( TS_UNIX )
- wfTimestamp( TS_UNIX, 0 )
- wfTimestamp( TS_UNIX, time() )
- intval( wfTimestamp( TS_UNIX, time() ) )
* Consistently use 1 as default instead of 0. Previously the
unwritten convention was that anything "final" max()'ed with 1,
and any internal method would use 0, but this wasn't applied
consistently made it fragile. There doesn't seem to be any
value in returning 0 only to have it maxed up to 1 (because if
the 0 would ever make it out alive, we'd be in trouble).
* wfTimestamp returns a string for TS_UNIX. In PHP this doesn't
matter much. In fact, max() takes number-like integers so
transparently, it even preserves it:
> max( 1, 3, '2' );
< 3
> max( 1, '3', 2 );
< "3"
Just cast it in one place at the very end (StartupModule)
instead of doing intval( wfTimestamp() ).
* Fix weird documentation claiming getModifiedTime can return
an array, or mixed.
* Remove 'version > 1 ? version : 1' logic in
ResourceLoader::makeLoaderRegisterScript. The client doesn't
have "0 means now" behaviour so this isn't needed. And the method
was only doing it for variadic argument calls.
Removal of quotes around timestamps reduced the size of the startup
module from 26.8KB to 25.9KB before gzip. After gzip the size was
and still is 5.7KB, though. (From 5456 bytes to 5415 bytes.)

We currently embed the full set of user options in a <script> tag in the HTML
output of every page. This is grossly inefficient, because the full set of
options is usually largely made up of site defaults which the user hasn't
customized.
So instead of doing that, let's emit the default options using one
ResourceLoader module and then apply the user's customizations on top.
This has the effect of slightly increasing the total bytes of JavaScript code
(because options that the user has customized will be emitted twice: once with
their default value in the user.defaults module, and then again with the
customized value in user.options). But this is more than offset by the
fact that the bulk of user options code (~4 kB uncompressed on enwiki) becomes
cacheable across requests.
Bonus round:
* Varnish gets to cache 4 kB fewer per page.
* Changes to the default options don't take 30 days to propagate.
