Explicitly track whether aggregate final functions modify transition state.

Browse Source 
Up to now, there's been hard-wired assumptions that normal aggregates'
final functions never modify their transition states, while ordered-set
aggregates' final functions always do.  This has always been a bit
limiting, and in particular it's getting in the way of improving the
built-in ordered-set aggregates to allow merging of transition states.
Therefore, let's introduce catalog and CREATE AGGREGATE infrastructure
that lets the finalfn's behavior be declared explicitly.

There are now three possibilities for the finalfn behavior: it's purely
read-only, it trashes the transition state irrecoverably, or it changes
the state in such a way that no more transfn calls are possible but the
state can still be passed to other, compatible finalfns.  There are no
examples of this third case today, but we'll shortly make the built-in
OSAs act like that.

This change allows user-defined aggregates to explicitly disclaim support
for use as window functions, and/or to prevent transition state merging,
if their implementations cannot handle that.  While it was previously
possible to handle the window case with a run-time error check, there was
not any way to prevent transition state merging, which in retrospect is
something commit 804163bc2 should have provided for.  But better late
than never.

In passing, split out pg_aggregate.c's extern function declarations into
a new header file pg_aggregate_fn.h, similarly to what we've done for
some other catalog headers, so that pg_aggregate.h itself can be safe
for frontend files to include.  This lets pg_dump use the symbolic
names for relevant constants.

Ordinarily, Postgres functions are expected to be true functions that
do not modify their input values. However, an aggregate transition
function, <emphasis>when used in the context of an aggregate</>,
is allowed to cheat and modify its transition-state argument in place.
This can provide substantial performance benefits compared to making
a fresh copy of the transition state each time.
</para>
<para>
Likewise, while an aggregate final function is normally expected not to
modify its input values, sometimes it is impractical to avoid modifying
the transition-state argument. Such behavior must be declared using
the <literal>FINALFUNC_MODIFY</> parameter. The <literal>READ_WRITE</>
value indicates that the final function modifies the transition state in
unspecified ways. This value prevents use of the aggregate as a window
function, and it also prevents merging of transition states for aggregate
calls that share the same input values and transition functions.
The <literal>SHARABLE</> value indicates that the transition function
cannot be applied after the final function, but multiple final-function
calls can be performed on the ending transition state value. This value
prevents use of the aggregate as a window function, but it allows merging
of transition states. (That is, the optimization of interest here is not
applying the same final function repeatedly, but applying different final
functions to the same ending transition state value. This is allowed as
long as none of the final functions are marked <literal>READ_WRITE</>.)

Note that whether or not the aggregate supports moving-aggregate
mode, <productname>PostgreSQL</productname> can handle a moving frame
end without recalculation; this is done by continuing to add new values
to the aggregate's state. It is assumed that the final function does
to the aggregate's state. This is why use of an aggregate as a window
function requires that the final function be read-only: it must
not damage the aggregate's state value, so that the aggregation can be
continued even after an aggregate result value has been obtained for
one set of frame boundaries.

the transition value in-place, aggregate final functions are generally
