The alignment is specified as a power of 2 (ie, actual alignment = 1 <<
alignment) allowing old object files to be compatible (as their
alignment is 0). This is necessary for (in part for #30) as it turned
out even global vectors were not aligned correctly.
Currently, only data spaces even vaguely respect alignment. This may
need to be fixed in the future.
They are both gone, and pr_pointer_t is now pr_ptr_t (pointer may be a
little clearer than ptr, but ptr is consistent with things like intptr,
and keeps the type name short).
The space is meaningless for op_* relocations as they are always in the
code space, but def_* relocations need to know which space holds the
location to be adjusted.
Since there is now a proper symbol table, defs are now just references to
memory locations and the symbol table takes care of duplicates.
Also, start using far data for ObjQC structures.
The qfo functions have been stubbed out until I figure out what to do with
object files in the new scheme.
