Acess control and config change checks

1) Fixed the issue that metadata was saved
as numbers. Was supposed to be saved as strings.
2) Added two functions. One is to check permissions
on the config file. Another to check if the file
has changed and thus the cinfiguration needs
to be reread.
3) Added unit test will sample code
and comments how to use the functions.
4) Added doxygen description in the comments.
5) Fixed couple typos and ommisions here and there.

[INI] Fixing crash detected on 64-bit system

This patch corrects original code to be
more on the safe side and check parameters
before using.
Instead of dereferencing metadata it is now
passed as reference to the next level.
It is not used there yet so no other new changes
needed so far.
