Implemented some print and copy routines.
Made empty srcpos objects that will be used later.
Protected .h file from multiple #include's.
Added srcpos_error() and srcpos_warn().

Many places in dtc use strdup(), but none of them actually check the
return value to see if the implied allocation succeeded. This is a
potential bug, which we fix in the patch below by replacing strdup()
with an xstrdup() which in analogy to xmalloc() will quit with a fatal
error if the allocation fails.
I felt the introduciton of util.[ch] was a better choice
for utility oriented code than directly using srcpos.c
for the new string function.
This patch is a re-factoring of Dave Gibson's similar patch.

All current callers of dtc_open_file() immediately die() if it returns
an error. In a non-interative tool like dtc, it's hard to see what
you could sensibly do to recover from a failure to open an input file
in any case.
Therefore, make dtc_open_file() itself die() if there's an error
opening the requested file. This removes the need for error checking
at the callsites, and ensures a consistent error message in all cases.
While we're at it, change the rror message from fstree.c when we fail
to open the input directory to match dtc_open_file()'s error message.

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.

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
