Currently "make all" for dtc will build (but not run) the testcase
binaries. This is a problem for cross compiles, because building the
tests will attempt to run the dumptrees utility on the host system,
which won't work if it's cross-compiled of course.
Although it would be possible to separately build host binaries,
there's not a lot of value in doing so since we don't have a facility
for cross-executing the testsuite anyway.
Therefore, remove the tests from the "all" target. It will still, of
course, be build as a prerequisite to "make check" which will run the
testsuite.

Apparently some versions of flex don't correctly parse the -o
parameter, if there's a space between the -o and its argument. So,
this patch removes it.

At present, the Makefiles will not rebuild trees.o or the dtb files
derived from it if testdata.h is updated. This is incorrect, and is
because of missing dependency information.
This patch fixes the problem by making sure that dependency
information is generated from trees.S and dumptrees.c.

Remove the uneccessary LDFLAGS from the top-level makefile. It only
added libfdt/ to the link path. dtc doesn't need libfdt at all, and
the testcases which do, already link libfdt.a by explicit path.

Previously, there were a few shift/reduce and reduce/reduce
errors in the grammar that were being handled by the not-so-popular
GLR Parser technique.
Flip a right-recursive stack-abusing rule into a left-recursive
stack-friendly rule and clear up three messes in one shot: No more
conflicts, no need for the GLR parser, and friendlier stackness.
Compensate by reversing the property list on the node.

This patch makes a number of Makefile cleanups and improvements:
- We use more generic rules to invoke flex and bison, which is
useful for some of the other changes.
- We use the name dtc-lexer.lex.c for the flex output, instead
of the default lex.yy.c. That means less potential for confusion if
dtc is embedded into other projects (e.g. the kernel).
- We separate out a Makefile.dtc designed for embedding into
other projects, analagous to Makefile.libfdt.
- Makefile.libfdt is cleaned up to be more useful based on
some actual trial runs of embedding libfdt in the kernel bootwrapper.
- Versioning related rules and variables are collected into
one place in the Makefile.

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.

This patch turns on optimisation in the Makefile by default. With the
optimizer on, some uninitialized variable warnings (one real, two
bogus) are now generated. This patch also squashes those again.
Currently, dtc relies on make's implicit rule to build the testcases.
This means that when not making verbosely (V=0, the default) there is
no message at all while relinking the testsuites. This can be very
confusing when updating libfdt.a (upon which the testcases depend) and
make appears to do nothing.
This patch corrects the situation, borrowing the rule used to link dtc
itself to link all the testcases as well.

This patch makes various improvements to dtc's make install target:
- libfdt is also installed. Specifically, libfdt.a and the
two export relevant header files, fdt.h and libfdt.h are installed.
- ftdump is no longer installed. It was only ever a
development debugging tool and may well go away at some point.
- In keeping with normal conventions, there is now a PREFIX
variable, allowing control of where things are installed (in /usr,
/usr/local, /opt, etc.).
- By default, installed into the user's home directory,
instead of /usr. This is friendlier for self-installers, package
builders can easily override PREFIX to restore the old behaviour.

This patch substantially revamps the dtc Makefiles, in particular
better integrating the Makefile for dtc proper with the Makefiles
imported from libfdt for libfdt and the shared testsuite. Notable
changes:
- No recursive make calls. Instead subsidiary Makefiles are
included into the top-level Makefile so we get a complete dependency
information.
- Common pattern rules, CFLAGS etc. shared between dtc, libfdt
and testsuite, rather than separate copies.
- Vaguely Kbuild-like non-verbose mode used by default, which
makes warnings more prominent.
- libfdt Makefile consists only of variable definitions and
helper rules, to make it more easily embeddable into other Makefile
systems.

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.

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.
