Update version and maintainer information

Set version information to 1.1 for the next libsmack release.
Change maintainer email from @intel.com to @linux.intel.com.
Cleaned up init code.

There was lot of clutter and misleading comments in the code
and some minor coding convention issues. This patch cleans up
init.c for the most part.
libsmack: clean up smack_accesses_add_modify()

This patch makes smack_accesses_add_modify() easier to follow by
changing variable names bit more self-documentative and less easier
to mix up with adding and deleting rules. This patch also fixes some
very minor coding style errors.

Also documentation of this function is cleaned up.
Fixes for doxygen errors coming from 3810596.

Doxygen errors that are regression from 3810596. Went in because
I forgot to install doxygen into my test environment.
Documented order in which access rules are applied to kernel.
