  This patchset introduces config file support for l3fwd
and its lookup methods LPM, FIB, and EM, similar to
that of l3fwd-acl. This allows for route rules to be
defined in configuration files and edited there instead
of in each of the lookup methods hardcoded route tables.

V6:
* Move config file parsing functions to separate files
  as to not bloat l3fwd code.
V5:
* Reintroduce hardcoded tables as to not break dts and
  allow for hardcoded tables to be used if no config
  files presented.
V4:
* Fix nondeterministic bug of segfault on termination of
  sample app.

  examples/l3fwd: add config file support for LPM/FIB
  examples/l3fwd: add config file support for EM
