cli_classic: refactor arguments parsing into separate func

Move variables that represent parsed options to `cli_options`
structure. This patchset also introduces the following functions:

- parse_options() which parses command line arguments and fills
the structure.
- free_options() that releases an allocated data from the
structure.

This is one of the steps on the way to simplify the main function
by using helper functions with descriptive names.
