Error reporting in push_input_file() is a mess. One error results in
a message and exit(1), others result in a message and return 0 - which
is turned into an exit(1) at one callsite. The other callsite doesn't
check errors, but probably should. One of the error conditions gives
a message, but can only be the result of an internal programming
error, not a user error.
So. Clean that up by making push_input_file() a void function, using
die() to report errors and quit.

Looking in the diretory dtc is invoked from is not very useful behavior.
As part of the code reorganization to implement this, I removed the
uniquifying of name storage -- it seemed a rather dubious optimization
given likely usage, and some aspects of it would have been mildly awkward
to integrate with the new code.

yyerror() is used by both dtc-parser.y and dtc-lexer.l, so move
the declaration to srcpos.h.

- Change include syntax to: /include/ "filename"
- Move private functions directly into dtc-lexer.l
- Define YYID for some older parser templates
Also fix a #include ordering problem around YYLTPE.

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
