Subject: kconfig_parser rewritten and now supports revers dependency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Most of the kconfig_parser is changed.
Now dependency are not copied before transfer to CNF and CNF expression is direcly extracted from kconfíg parsed output structures.
