There are quite a lot of testcases in the dtc testsuite (recently
imported from libfdt). It can be easy to miss a stray FAIL result in
the midst of all the rest. To improve this, this patch adds a summary
to the end of the testsuite results giving the total number of tests
along with the number of PASSes FAILs and other results.

The libfdt functions are supposed to behave tolerably well when practical,
even if given a corrupted device tree as input. A silly mistake in
fdt_get_property() means we're bounds checking against the size of a pointer
instead of the size of a property header, meaning we can get bogus
behaviour in a corrupted device tree where the structure block ends in
what's supposed to be the middle of a property.
This patch corrects the problem (fdt_get_property() will now return
BADSTRUCTURE in this case), and also adds a testcase to catch the bug.
fdt_property_offset() is the only function in the library returning a
direct offset to a property, and no function takes such an offset
(they only take offsets to nodes, not properties). Furthermore the
only client uses for this function I can think of involve immediately
translating the offset into a pointer, effectively duplicating the
internal function _fdt_getprop()
This function abolishes fdt_property_offset(), replacing it with
fdt_get_property(), a renamed and now externally visible version of
_fdt_getprop().
