Cargo lists storing lists of cargo for each carrier

Persistent game state encodes "who carries what" by storing the
carrier uid in the cargo.  Cargo lists augment that: they store lists
of cargo for each carrier.  They are not persistent.

New unit_cargo_init() to compute the cargo lists from game state.
Call it in ef_init_srv() and at the end of update_main().

New unit_onresize() to resize the cargo list data structure.
Installed as units' struct empfile callback onresize to make them
resize automatically with the unit files.

New unit_carrier_change() to update cargo lists when carriers change
in game state.  Convenience wrappers pln_carrier_change(),
lnd_carrier_change() and nuk_carrier_change().  Call them from
prewrite callbacks to keep cargo lists in sync with game state.

To make that work, unused units must not point to a carrier.  Add new
pln_oninit(), lnd_oninit() and nuk_oninit() take care of newly created
units.  Change lnd_prewrite() and nuk_prewrite() to take dead land
units and nukes off their carrier.  pln_prewrite() did that already.

New unit_cargo_first(), unit_cargo_next() to traverse cargo lists.
Convenience wrappers lnd_first_on_ship(), lnd_first_on_land(),
lnd_next_on_unit(), pln_first_on_ship(), pln_first_on_land(),
pln_next_on_unit() and nuk_on_plane().  The latter is disabled for now
because it clashes with an existing function.
