DTC: Add support for a C-like #include "file" mechanism.
Keeps track of open files in a stack, and assigns
a filenum to source positions for each lexical token.
Modified error reporting to show source file as well.
No policy on file directory basis has been decided.
Still handles stdin.
Tested on all arch/powerpc/boot/dts DTS files
