s4:schema_syntax.c - Change also here counters to "unsigned" where needed
Counters which are used in the way "for (i = 0; array[i] != NULL; i++)" I
modified to "unsigned" since for sure we don't want to have negative array
indexes there.
There were many counter variables typed "uint32_t". This isn't fully correct
since those count LDB objects. The amount is saved in a "num_*" variable which
is "unsigned" without a bitlength specification. Therefore change also these
counters to be plain "unsigned".
