New upstream release:
Changes since v1.6.0 include:
 * A number of bugfixes
 * Fix many warnings with -Wsign-compare
 * Add compilation with meson (not used by default so far)
 * Yet another revamp of how we handle unaligned accesses
 * Added a number of extra checks for common tree errors
   * Checks for interrupt providers
   * i2c reg properties
   * Tighten checking of gpio properties
 * Reduce dependencies when building libfdt only
 * Allow libfdt.h header to be used from C++ more easily
 * Accept .dtbo extension for overlays
 * Update valid node and property characters to match current devicetree spec
 * Add several checks for root node sanity in fdt_check_full()
 * Somewhat more robust type labelling for the benefit of yaml output
