Tweak the API for per-datatype typmodin functions so that they are passed

Browse Source 
an array of strings rather than an array of integers, and allow any simple
constant or identifier to be used in typmods; for example
	create table foo (f1 widget(42,'23skidoo',point));
Of course the typmodin function has still got to pack this info into a
non-negative int32 for storage, but it's still a useful improvement in
flexibility, especially considering that you can do nearly anything if you
are willing to keep the info in a side table.  We can get away with this
change since we have not yet released a version providing user-definable
typmods.  Per discussion.
