Remove some unused buildsym functions 

Now that the DWARF reader uses the builder-based API, we can remove a
few "legacy" functions that were only ever called by it.

The compunit symtab pointer ("cust") is returned from both start_symtab
and end_symtab to simplify the debug info readers.
There are minor variations on this, e.g., dwarf2read.c splits end_symtab
into two calls: end_symtab_get_static_block, end_symtab_from_static_block,
but all debug info readers follow this basic flow.
Reading DWARF Type Units is another variation:
scoped_free_pendings free_pending;
cust = start_symtab (...);
... read debug info ...
cust = end_expandable_symtab (...);
And then reading subsequent Type Units within the containing "Comp Unit"
will use a second flow:
scoped_free_pendings free_pending;
cust = restart_symtab (...);
... read debug info ...
cust = augment_type_symtab (...);
dbxread.c and xcoffread.c use another variation:
scoped_free_pendings free_pending;
