Use ptid from regcache in almost all remaining nat files

This patch contains almost all of the remaining changes needed to make
to_fetch_registers/to_store_registers/to_prepare_to_store independent of
inferior_ptid.  It contains only some "trivial" changes, the more
complicated ones are in separate patches.
