Purify support:

* Add third_party/purify/pure_api.c to the base\base_lib.scons sources.
* Support specification of CHROME_BUILD_TYPE (and CHROMIUM_BUILD
  while we're here) either on the command line or as an
  external environment variable.
* Fix syntax error in release_impl_purify.scons (previously unused).
* Add a central $CHROMIUM_CC_OPT_FLAGS variable (included in $CCFLAGS)
  that can be used to set explicitly the optimization level without
  having to worry about optimization flags being pulled in from other
  settings files.
