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

libdt.c was an attempt at creating a device tree handling library
within the dtc codebase. However, it was never even close to
completion, and is entirely obsoleted by it's spiritual descendent,
libfdt (currently a separate package). This patch, therefore, removes
libdt.c entirely, along with its only reference in the Makefile, an
unused variable.
