1) Add test for Bug 99970 Comment 6 & fix
2) Allow chrome.send to be mocked outside of preLoad call.
3) add chrome.originalSend to allow mocked messages to pass through to C++.

Also to address need for .cc file to be correct for clang, and prevent ugliness in js with a lot of GEN lines, allow the header and .cc to not have a suffix, and the generated file to end in -gen.cc.  While doing this, addressed crbug.com/102794 to put in <(INTERMEDIATE_DIR) preventing collisions across rules.
