Description

API performance enhancements (bug 13511):

Replaced $wgAPIUCUserPrefixMinLength with the more generic $wgAPIMaxDBRows
Added ApiBase::checkRowCount() which checks whether the amount of rows to be scanned is acceptable (i.e. <$wgAPIMaxDBRows). Not using this anywhere (yet?), but it's nice to have
Killed a filesort in the usercontribs query, query is now indexed nicely
Dropped the minimum length for ucuserprefix since it's no longer needed (query optimized)
Removed drnamespace from list=deletedrevs (filesorts 8M rows for drnamespace=0)
Support multiple orderings in ApiBase::addWhereRange()
