Copy from http://chrome-reviews.prom.corp.google.com/1237 (new gcl changelist model).

Description was:
Conditionally include personalization/ code by surrounding
the hooks into this module with #ifdef CHROME_PERSONALIZATION
in various .h/.cc files.

Building with the module requires adding this macro as a preprocessor
definition in build/internal/essential.vsprops, and adding it to the
VCResourceCompiler tool's command line (using /d). We will try and
make this easier in the future.
