utils: apply access rules to load/load2 in one shot

Open load/load2 only once. Inside the callback only collect rules
using smack_accessed_add_from_file(). Finally, apply access rules
in a single slot.

This was inspired by feedback from Rafal Krypa <r.krypa@samsung.com>.

This change should be backward compatible for kernels without l-mode support
as long as requested permissions don't contain this mode.

utils: use common code for apply_rules and apply_cipso

Code for apply_rules() has been rewritten to use opendir() and readdir(),
but apply_cipso() remained implemented with nftw().
This patch implements both applying functions with opendir() and readdir()
using a common internal function apply_dir().
The resulting code is 45 lines shorter and keeps directory traversal logic
in single place.

tests: starting point for stress testing

This starting point for stress testing. Generates 200 files each
with 10000 random access rules. Does not yet support modify rules.
Next step would be probably making this more parametrized.

chsmack: using linux constants for Smack's names

It is better to rely on the centralisation of names in a
single file: it can avoid errors.

The declarations of <linux/xattr.h> contains the definitions
of the names of the Smack's security attributes.

As Smack only runs on Linux and libsmack doesn't provides
a centralized version of the names of the security attributes
(because it were not needed), using the linux header seems
to be a good choice.

chsmack: put usage string at head

Setting it at head is a reading improvement for
developpers that can quickly show the usage of the
program. It also makes the main function more readable.
