Add support for using gcc's visibility pragma to treat all function and method declarations as "hidden" unless declared otherwise. Create wrappers for system headers that cause them to be treated as default-visibility declarations. This gives a substantial code size and performance win on compilers that support it, and should show up on the gruff tinderbox. Bug 273336, r=darin sr=dbaron.
