[PATCH 00/10 v2] usage()/--help clean up & unification

[Mike Frysinger]

Each utility currently open codes how they process options and
implement usage().  This leads to inconsistent behavior and output
which sucks.  A bunch also get common things wrong (like sending
--help to stderr).

Rather than go through them one by one and fix their bugs, start
a new mini framework in the util.[ch] code base.  This allows the
utils to be much more data driven in their approach to options --
they declare certain structures with the right format, and then
call usage() as needed.  The new util code takes care of the rest.

I also snuck in a few minor fixes in this patch series that I
noticed as I was hacking on things.  Really I just wanted a --scan
option in the fdtdump tool :).

For the v2 series, I fixed a compile/output bug in one of the
patches and this now passes `make check`.  I also added a --debug
option to fdtdump.

Mike Frysinger (10):
  utilfdt_read_err: use xmalloc funcs
  utilfdt_read: pass back up the length of data read
  die: constify format string arg
  util_version: new helper for displaying version info
  fdtdump: make usage a bit more friendly
  fdtdump: add a --scan option
  dtc/fdt{get,put}/convert-dtsv0-lexer: convert to new usage helpers
  util: drop "long" from usage helpers
  util: add common ARRAY_SIZE define
  fdtdump: add a debug mode
