- Update patch bit more for sanity checks. Done by rsassu@suse.de:
* vsftpd-path-normalize.patch

- Add back patch attempting to fix bnc#900326 bnc#915522 and
bnc#922538:
* vsftpd-path-normalize.patch

- Reset filter patch to match fedora, my work will be restarted
in one-off patch to make the changes stand out. Add rest of
RH filtering patches:
* vsftpd-2.2.0-wildchar.patch
* vsftpd-2.3.4-sqb.patch
* vsftpd-2.1.0-filter.patch

- Work on the filter patch and split out the normalisation of the
path to separate str function, currently commented out so I
avoid huge diffing.
* vsftpd-2.1.0-filter.patch
