Nicolas Iooss 02a7d77ef2 libsepol: make parsing symbol table headers more robust
When hll/pp loads a policy file which has been modified so that the
nprim field of one of its non-empty symbol table was changed to zero, it
crashes with a segmentation fault. A quick analysis leads to
"p->sym_val_to_name[i] = (char **)alloc(p->symtab[i].nprim, sizeof(char
*));" in policydb_index_others(), which is not executed when
p->symtab[i].nprim is zero even though there are items in
p->symtab[i].table.

Detect such an oddity in the policy file early to exit with a clean
error message.
