Log Message:
Remove VMCMD_TOPDOWN since it's no longer.  Redo my last rework.  Move
VM_DEFAULT_ADDRESS from elf*_makecmds to elf*_load_file.  In load_file,
actually determine ahead of time how much space will be needed and pass
that to VM_DEFAULT_ADDRESS.  Now we have a relatistic starting address
so we can do the loading of psections normally with no extra topdown
code in load_psection.  Also, if there is a gap in betweeen psections
zero map an inaccessible region between (just like ld.elf_so does) to
avoid inadvertant mmaps in the gap.
