- revert the permission change, we will revisit it at a later point

- we give the config files and directory the permissions
u=rwx,go=rx root:mysql, if we give the mysql group permissions we
should not need to leave the permissions open for others.
change permissions to u=rwx,g=rx,o=

- exclude galera files if we build without this feature.

- instead of setting the permissions in the files section inherit
what ever we set during installation. This simplifies the code
for the file section a lot. and we have a lot more flexiblity to
fix permissions in %install

- added fix-lock-rollback-assert-abort.patch
fix an abort when a transaction is rolled back
- track all patches in a series so we can easily set up a quilt
tree without requiring all the devel packages
