* Reverted HttpFunctions.php to r45549 and renamed wgSyncHTTPTimeout back to wgHTTPTimeout * Edited out the asynchronous features from UploadFromUrl. Made fetchFile() use the curlCopy() function from new-upload r47811 instead of Http::doDownload(). Wrote my own URL validity check to avoid having to use either of the two buggy precedents. * Removed UploadFromChunk * Removed chunk upload and background status from ApiUpload.php * Reverted r54669, use of addScriptClass() * Left getHeadScripts() in its current location (OutputPage) instead of moving it back to SkinTemplate, just added wikibits.js to it to replace the removed addCoreScripts2Top()
