[PATCH 1/4][RFC] stkutil: Refactor command parser error handling

[Denis Kenzior]

Hi Andrew,

> When parsing the full command fails but Command Details has been parsed,
> return a struct stk_command containing this information and the type of
> parsing problem found.  We need the command details to be able to
> even respond to the command.

> This patch also makes the parser skip over unknown data objects found

> The tests succeed but please check that it doesn't break the logic.

I'm ok with the approach, however the patch no longer applies.  Can you please 
rebase and resubmit?

Thanks,
