[pmg-devel] [PATCH WIP api 02/11] negation: parse negation value into objects

[Leo Nunner <l.nunner@proxmox.com>]

Expand the parsing code so that the 'negate' field is written into
objects for further handling. Two new functions are introduced: one for
reading a specific object-rule mapping (and its values), the other to
set the 'negate' value for such an object.
