This commit contains all the required changes to our source files and build scripts (hopefully). A next commit will remove the old stuff of SpiderMonkey 1.8.5. Spcial thanks to: - H4writer who helped a lot mainly with the performance issues we had/have, but also with other problems or questions. - Leper for the review. - Historic_bruno for implementing the build scripts on Mac OS X and testing on the Mac. - The people from the #jsapi channel and from mozilla.dev.tech.js-engine who answered a lot of questions and helped solving problems. - All the other people who helped Refs #1886 Fixes #2442 Fixes #2416 This was SVN commit r14877.
