I've recently worked with a FreeBSD developer, getting dtc and libfdt working on FreeBSD. This showed up a number of portability problems in the dtc package which this patch addresses. Changes are as follows: - the parent_offset and supernode_atdepth_offset testcases used the glibc extension functions strchrnul() and strndupa(). Those are removed, using slightly longer coding with standard C functions instead. - some other testcases had a #define _GNU_SOURCE for no particular reason. This is removed. - run_tests.sh has bash specific constructs removed, and the interpreter changed to /bin/sh. This apparently now runs fine on FreeBSD's /bin/sh, and I've also tested it with both ash and dash. - convert-dtsv0-lexer.l has some extra #includes added. These must have been included indirectly with Linux and glibc, but aren't on FreeBSD. - the endian handling functions in libfdt_env.h, based on endian.h and byteswap.h are replaced with some portable open-coded versions. Unfortunately, these result in fairly crappy code when compiled, but as far as I can determine there doesn't seem to be any POSIX, SUS or de facto standard way of determining endianness at compile time, nor standard names for byteswapping functions. - some more endian handling, from testdata.h using the problematic endian.h is simply removed, since it wasn't actually being used anyway.
