Alexander Amelkin 73d6af5782 Add support for command-specific completion codes
Some commands may return command-specific completion codes.
Now they are all reported as 'Unknown'.
Add helper functions to support such command-specific codes.
Command handlers will need to define their own valstr arrays
with completion code descriptions and then use specific_val2str()
instead of generic val2str() to convert the completion code into
a string.

Also reduce code duplication in helper.c
