Add support to the dcb tool for the following two DCB objects:

- APP, which allows configuration of traffic prioritization rules based on
  several possible packet headers.

- DCBX, which is a 1-byte bitfield of flags that configure whether the DCBX
  protocol is implemented in the device or in the host, and which version
  of the protocol should be used.

Patches #1 and #2 fix issues in the current DCB code.

Patch #3 adds a new helper for finding a name of a given dsfield value.
This is useful for APP DSCP-to-priority rules, which can use human-readable
DSCP names.

Patches #4, #5 and #6 extend existing interfaces for, respectively, parsing
of the X:Y mappings, for setting a DCB object, and for getting a DCB
object.

In patch #7, support for the command line argument -n / --no-nice-names is
added. The APP tool later uses it to decide whether to format DSCP values
as human-readable strings or as plain numbers.

Patches #8 and #9 add the subtools themselves and their man pages.
