When reading a properties file with a line containing a binary zero as first
character, an array access at index -1 is attempted, because strlen considers
this as an empty string (len = 0). The following array access 'line[len - 1]'
accesses the array at index -1.
Fix this by checking the line length and skip empty lines.

skipped. Empty lines are also skipped.

but for better usability store and display it in uppercase always,
regardless in whatever case it was specified.

Comma separated strings are used in property values to store
multiple values in one property. These helper functions allow to
work with such comma separated strings.

In preparation for a new feature, introduce property file
handling routines. A property file stores key value pairs
in a text file. Optionally a hash of all keys and values
contained in the properties file can be generated to
ensure integrity of the properties file and to detect
manual modifications.
