It is true, the attribute server can be disabled, but using
--enable-attrib, the example will add the attributes in the "database"
even it is not available.

We decided to use only one configure option and add "AttributeServer"
in the main.conf to disable the server. Now, If everyone agrees, we
can split --enable-attrib allowing to disable/enable client and server
separately.

BTW, the patch still valid.This code will not be used anymore, the
plan is to implement <<Client Characteristic Configuration>>

It will take some time to remove the example.c, the GATT profiles that
are being proposed are not using all the features that we need to test
the client side.
