Use lmalloc() rather than the fixed (obsolete) bounce buffer, and set
the gateway for PXE stacks that need it.

It appears that there still are PXE stacks in the field which needs
the crutch of being pointed to the default gateway.  As such, put all
the IP information into a single memory structure and allow modules to
see it.

The ifcpu.c32 and ifcpu64.c32 modules take arguments including
the form <true_label> -- <false_label>.  It is convenient to
allow these labels to be not just a single word, but to include
parameters.  This is useful for <TAB>-editing and modifying the
command-line to include parameters you'd like to pass.

Since load_end_addr and bss_end_addr may be incomplete, we can't
actually use them for information.  An alternative would be to
actually modify these fields in-memory, but it is unclear if that is
permitted by the spec.
