neither symdel nor symstat were used anywhere. syminit was used but
had no effect. both syminit and symdel dereference pointers after
freeing them. symstat can be tricked into writing beyond the bounds of
its array

syminit() attemts to reset the symbol table by freeing
all the hash table entries, tho the code is buggy having
a obviously use after free bug.
as syminit() is only called once in main when it does not
contain any symbols, the bug never occured.
removing the unneccesary code alltogether.
