Support impure initialise and finalise predicates in user code. In order to
support this the arity of the initialise or finalise predicate can no longer be
optionally omitted from the declaration. Supporting impure arity zero
initialise/finalise declarations removes the restriction that every module that
has an initialise/finalise declaration must import the io module.
Allow initialize/finalize to be used as synonyms for initialise/finalise.
Improve the documentation of initialise/finalise declarations.
In particular:
- mention the above changes.
- mention that they may be cc_multi.
- specify the order in which they invoked with respect to
standard library initialisation/finalisation.
- mention that these declarations are not currently available
on non-C backends.
compiler/make_hlds_passes.m:
Support impure user initialise/finalise predicates.
compiler/mercury_to_mercury.m:
Write out the arities of the predicates specified in
initialise and finalise declarations.

Add an arity field to the initialise and finalise items.
compiler/prog_io.m:
Don't allow the arity to be omitted in initialise and finalise
declarations.
