Move many files that were suffixed Win.cpp to Chromium.cpp, and place them in chromium/ subdirectories. We still build these files with PLATFORM(WIN) defined.
In this change, I also killed off LogWin.{h,cpp} since we don't use it. So, you will see some changes related to that. R=dglazkov,tony Review URL: http://codereview.chromium.org/7419 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@3427 0039d316-1c4b-4281-b951-d872f2087c98
