Revert 207805 "Differential updates for components. We are addin..."
Unit tests fail on Mac Dbg with this patch: http://build.chromium.org/p/chromium.mac/buildstatus?builder=Mac%2010.6%20Tests%20%28dbg%29%284%29&number=29470 and http://build.chromium.org/p/chromium.mac/buildstatus?builder=Mac%2010.7%20Tests%20%28dbg%29%284%29&number=12750 > Differential updates for components. We are adding support for delivering delta updates for Chrome components. Initial platform support for the patcher is Windows only. The update response includes both the full update and, if available, the differential update. The differential update is tried first, then the full update, if needed. > > BUG=245318 > > Review URL: https://chromiumcodereview.appspot.com/15908002 TBR=sorin@chromium.org Review URL: https://codereview.chromium.org/17551004 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@207823 0039d316-1c4b-4281-b951-d872f2087c98
