Rearrange structures prog and component.

* config_array_to_argv (config_array_to_argv): Take four arguments.
Return argc in the memory location pointed to by the 4th one (unless NULL).
All callers updated.
(_cb_command): Fill both comp->argv and comp->argc.
(component_keywords): Pass pointer to struct component to _cb_command.
* src/pies.h (struct component): New member `argc'.
* src/progman.c (struct prog): Move idx to v.p; change its type to unsigned.
Remove v.p.argc. All uses updated.
(numprog): Rename to numcomp; change type to unsigned.
(prog_lookup_by_idx): Check only elements of type
TYPE_COMPONENT.
