tests will need fdt type definitions provided in a subsequent patch
to libfdt_env.h. Since libfdt.h includes libfdt_env.h in the right
order anyway, just remove the fdt.h include.

This patch marks various functions not shared between c files
'static', as they should be. There are a couple of functions in dtc,
and many in the testsuite.
This is *almost* enough to enable the -Wmissing-prototypes warning.
It's not quite enough, because there's a mess of junk in the flex
generated code which triggers that warning which I'm not yet sure how
to deal with.

This patch adds functions for dealing with the compatible property.
fdt_node_check_compatible() can be used to determine whether a node is
compatible with a given string and fdt_node_offset_by_compatible()
locates nodes with a given compatible string.
Testcases for these functions are also included.

At present, the fdt_subnode_offset() and fdt_path_offset() functions
in libfdt require the exact name of the nodes in question be passed,
including unit address.
This is contrary to traditional OF-like finddevice() behaviour, which
allows the unit address to be omitted (which is useful when the device
name is unambiguous without the address).
This patch introduces similar behaviour to
fdt_subnode_offset_namelen(), and hence to fdt_subnode_offset() and
fdt_path_offset() which are implemented in terms of the former. The
unit address can be omitted from the given node name. If this is
ambiguous, the first such node in the flattened tree will be selected
(this behaviour is consistent with IEEE1275 which specifies only that
an arbitrary node matching the given information be selected).
This very small change is then followed by many more diffs which
change the test examples and testcases to exercise this behaviour.

This patch adds a function to libfdt to locate nodes containing a
property with a specific value.
