622d02fb21 Instead of iterating through all properties looking for a match, if asked
for a specific property, look it up directly.

8cc2c16287 - Change ofwdump(8) to use sysexits(3) exit codes.
- Make the code use the new OFIOCMAXVALUE instead of defining the maximum
  length of property values locally.
- Move the application specific parts from ofw_util.c to ofwdump.c in
  order to make ofw_util.c more library-like. While ofw_dump_properties()
  could be made non-specific to ofwdump(8) it's currently optimized for
  use in ofwdump(8) and making it a library-like function would just
  complicate the code unnecessarily.
- Minor clean-up in ofw_util.c, e.g. make its use of getopt(3) the way
  it's described in style(9), make its usage() static, etc.
- Add a comment in ofw_util.c about why it doesn't call usage() when
  neither the "-a" option nor a node-name where given.
- Add ofw_optnode() and ofw_setprop(), helper functions for the
  OFIOCGETOPTNODE and OFIOCSET ioctls respectively, to ofw_util.[c,h].
- Be consistent with the use of 'const' in ofw_util.[c,h] and add 'const'
  to the function arguments that are acutally const but weren't declared
  as such.
- Mark WARNS=6 clean.

1b6eef5b4e Add a utility to examine the OpenFirmware device tree (on sparc64). This
allows access to detailed machine configuration information, and should
be especially useful to gather information for driver-related bug
reports.
