Bugfix: The f_console project after writing unit tests.

Rename has_values to values_total to better communicate the intent of the property.

Expand out the macros across lines.

In f_console_identify() the strnlen() function is not properly handling when the character pointer is NULL, resulting in a segfault.
While this might be considered a bug in strnlen(), just make sure that a NULL pointer is not sent to strnlen().

Miscellaneous code structure cleanups.

Replace allocation macros with actual functions.
