LibC: Avoid ninja-imports of system functions

Browse source 
This adds a new header <sys/internals.h>, which provides access to LibC internals.
This is in the interest of type-checking LibC itself, as well as enabling less-hacky
access for uses like LinkDemo.

And, of course, this progresses LibC towards building cleanly with -Wmissing-declarations.
