Various improvements for ia64:
o s/TARGET_XFER_DIRTY/NATIVE_XFER_DIRTY/g to be conformant,
o Handle TARGET_OBJECT_DIRTY for core files. Required on Linux,
o Replace ia64_fbsd_supply_fpregs() and ia64_fbsd_supply_gregs()
with supply_fpregset() and supply_gregset() resp. Needed to
support libthread_db.
o For target_read_partial(), pass the address of bspstore as the
annex instead of bspstore itself. This fixes crossbuilds. The
annex is a pointer, while bspstore is a ULONGEST.
o In ia64_frame_prev_register(), handle dirty stacked registers.

Remove fbsd-thread.o, it's not for consumption yet.
