Disabled MSVC #4267 warnings in common.gypi to enable x64 builds for Windows. Fixed MSVC #4267 warnings in test/testsupport. Added third_party/directxsdk to .gitignore. With http://review.webrtc.org/1070008 landed, this should make it possible to build for x64 on Windows. BUG=1348 TEST=Compiling with http://review.webrtc.org/1070008 applied: set GYP_DEFINES="target_arch=x64" set GYP_GENERATORS=ninja gclient sync ninja -C out\Debug_x64 Review URL: https://webrtc-codereview.appspot.com/1060008 git-svn-id: http://webrtc.googlecode.com/svn/trunk@3464 4adac7df-926f-26a2-2b94-8c16560cd09d
