Add predecessor column dd and withpoints dd

[cvvergara]

predecessor column

As the pgr_withPointsDD and pgr_drivingDistance were modified and added the column depth on the results, this PR adds an aditional column pred on the results.

SELECT * FROM pgr_drivingDistance(
  'SELECT id, source, target, cost, reverse_cost FROM edges',
  array[11, 16], 3.0, equicost => true);
 seq | depth | start_vid | pred | node | edge | cost | agg_cost
-----+-------+-----------+------+------+------+------+----------

Some standardization

Renaming new internal functions and not using default values on them:

• _pgr_v4drivingdistance -> _pgr_drivingdistancev4
• _pgr_v4withPointsDD - > _pgr_v4withpointsDDv4
• _v4pgr_ksp -> _pgr_kspv4
• _v4trsp -> _pgr_trspv4

TODO:

• [x] Adjust the documentation
• [x] Update News and Release notes

Additionally

• Some standardization of internal functions:

_pgr_v4drivingDistance -> _pgr_drivingDistancev4 _pgr_v4withPointsDD -> _pgr_withPointsDDv4 _v4pgr_ksp -> _pgr_kspv4 _pgr_v4withPointsKSP -> _pgr_withPointsKSPv4 _trsp -> _pgr_trspv4

• For new internal functions, app parameters are unnamed and without default values
• Detected more deprecated functions and adjusted the comments about the deprecation
