ad4f54ae2b Return a non-zero exit code if an error occurs during dts parsing.
Previously, only failure to parse caused the reading of the tree to fail;
semantic errors that called yyerror() but not YYERROR only emitted a message,
without signalling make to stop the build.

92cb9a25b1 dtc: Add many const qualifications
This adds 'const' qualifiers to many variables and functions.  In
particular it's now used for passing names to the tree accesor
functions.

dc941774e2 dtc: Merge refs and labels into single "markers" list (v2)
Currently, every 'data' object, used to represent property values, has
two lists of fixup structures - one for labels and one for references.
Sometimes we want to look at them separately, but other times we need
to consider both types of fixup.

I'm planning to implement string references, where a full path rather
than a phandle is substituted into a property value.  Adding yet
another list of fixups for that would start to get silly.  So, this
patch merges the "refs" and "labels" lists into a single list of
"markers", each of which has a type field indicating if it represents
a label or a phandle reference.  String references or any other new
type of in-data marker will then just need a new type value - merging
data blocks and other common manipulations will just work.

While I was at it I made some cleanups to the handling of fixups which
simplify things further.

91967acabd dtc: -Odts produces v1 output
This patch alters the -Odts mode output so that it uses dts-v1 format.
This means that dtc -Idts -Odts used on a v0 dts file will convert
that file to v1.

d3ea6e5f96 dtc: Make -Idts -Odts preserve property-internal labels
This patch changes -Odts mode output so that labels within property
values in the input are preserved in the output.  Applied on top of
the earlier patch to preserve node and property labels in -Odts mode,
this means that dtc in -Idts -Odts mode will transfer all labels in
the input to the output.

ed01ae41e2 dtc: Refactor printing of property values in -Odts mode
Currently the main recursive tree printing function,
write_tree_source_node(), calls guess_type() to apply heuristics to
see how to print a property value, then calls the appropriate
write_propval_*() function to print it.

However, future heuristics for handling internal labels and the like
don't work well this way.  Therefore, this patch refactors things to
have write_tree_source_node() call a new write_propval() function,
which incorporates the heurstic logic from guess_type() and also calls
the right function to do the actual printing.

No behavioural change.

02563ad023 dtc: Make -Idts -Odts preserve node/property labels
This patch changes -Odts mode output so that labels on properties,
nodes and memreserve entries in input source are preserved in the
output.

Preserving labels within property values is trickier - another patch
coming later.

5a98ddd10a dtc: Improve -Odts output
This patch makes improvements to the way properties are printed when
in dtc is producing dts output.
	- Characters which need escaping are now properly handled when
printing properties as strings
	- The heuristics for what format to use for a property are
improved so that 'compatible' properties will be displayed as
expected.
	- escapes.dts is altered to better demonstrate the changes,
and the string_escapes testcase is adjusted accordingly.

63dc9c7113 dtc: Whitespace cleanup
This large patch removes all trailing whitespace from dtc (including
libfdt, the testsuite and documentation).  It also removes a handful
of redundant blank lines (at the end of functions, or when there are
two blank lines together for no particular reason).

As well as anything else, this means that quilt won't whinge when I go
to convert the whole of libfdt into a patch to apply to the kernel.

e45e6fd274 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
