jim-nvp is moving from jimtcl to openocd

The jim-nvp code is specific to openocd, so it belongs in openocd,
not in the core jimtcl.

/** Name Value Pairs, aka: NVP
* - Given a string - return the associated int.
* - Given a number - return the associated string.
* .
*
* Very useful when the number is not a simple index into an array of
* known string, or there may be multiple strings (aliases) that mean then same
* thing.
*
* An NVP Table is terminated with ".name = NULL".
*
* During the 'name2value' operation, if no matching string is found
* the pointer to the terminal element (with p->name == NULL) is returned.
*
* Example:
* \code
* const Jim_Nvp yn[] = {
* { "yes", 1 },
* { "no" , 0 },
* { "yep", 1 },
* { "nope", 0 },
* { NULL, -1 },
* };
*
* Jim_Nvp *result
* e = Jim_Nvp_name2value(interp, yn, "y", &result);
* returns &yn[0];
* e = Jim_Nvp_name2value(interp, yn, "n", &result);
* returns &yn[1];
* e = Jim_Nvp_name2value(interp, yn, "Blah", &result);
