leaving these in the "to be reviewed" section because I am not entirely
sure.

I think these cases are:

- ses_set_attr / beresp_filter_fixed: flexelint bug? Looks like it does not
  register use via macros

- ObjGetU32/Lck_DestroyClass API

- HTTP_IterHdrPack / SYMTAB_NOERR cases we do not want to make static
  by design
