    syscall.*execve: Fix argv access on newer kernels
    
    Kernel commits ba2d0162 and 0e028465, merged in 3.0, refactored the
    arguments of do_execve and compat_do_execve, such that "__argv"
    is now the name of the incoming pointer, and "argv" is a local
    struct user_arg_ptr.  Our tapset must adapt to the new names.
    
    * tapset/syscalls.stp (syscall.execve, syscall.compat_execve): Use
      @defined to set an internal local __argv to either $__argv or $argv,
      then use that for the other __get_argv calls.
    * testsuite/buildok/twentyseven.stp: Update for $__argv vs. $argv.
    * testsuite/systemtap.base/pointer_array.stp: Ditto.

    rhbz717136: Fix SDT relocations in prelinked modules
    
    * tapsets.cxx (sdt_query::handle_probe_entry): The debuginfoless SDT
      addresses are relative to the ELF file, so get only that bias.  The
      DWARF bias is not interesting here.
      (sdt_query::setup_note_probe_entry): Add the ELF bias to the semaphore
      address too, so record_semaphore can completely relocate it.
      (sdt_query::record_semaphore): SDT V3 semaphores need relocation too,
      now removing both the bias and prelinking effects.
