Replace ToLower calls to the new format

Replaces
  base::StringToLowerASCII(string)
with
  base::ToLowerASCII(string)
This form is 1:1 search and replace.

A bunch of places did something like this:
  std::string foo(something_else);
  base::StringToLowerASCII(&foo);
which became:
  foo = base::ToLowerASCII(something_else);

A couple places really wanted in-place changing and they became:
  foo = base::ToLowerASCII(foo);

There was pretty trivial cleanup in chrome_main_delegate.cc chrome/test/chromedriver/server/http_handler.cc (fix indenting).

There was more cleanup in:
chrome/installer/util/language_selector.cc and components/plugins/renderer/mobile_youtube_plugin.cc

In components/history/core/browser/url_utils.cc I removed the call since it was calling ToLower on the host name out of a GURL, which is already guaranteed to be lower-case.

NOPRESUBMIT=true
(due to touching code with wstrings)
