Standardize StringToInt{,64} interface.

These changes address issue #106655.  All variants of StringToInt have been
converted to use the StringPiece class.  One instance of conversion, in
chrome/browser/history/text_database.cc, required copying an underlying
string.  This is because the string type in question could use 8 or 16
bit characters depending on the OS type, and because StringPiece is not
implemented as a template, the code cannot specify whether to create a
StringPiece or StringPiece16.  This should be remedied in a future CL.
