Naming convention of Config FS should not be exposed
to user of library. All API functions should use
configuration ID (configuration number) as unique
identificator and configuration label as human
readable description.

User of library should not use directly function name but
only type of the function and name of instance. Using this
will separate user for naming convention on Config FS.

Assumption that all malloc() and read()/write() finish correctly
is too bold. Errors should be handled and propagated to upper
layers of library and returned to user.

Config strings should not be cached in library.
Removing internal strings structure allowed to add
full support for multilingual strings.
