Change the length of the obs-sdom-array array.
In the execution this resizes (to grow or shrink) the underlying Common Lisp array. The logical definition is based on resize-list:
Function:
(defun resize-sdominfos$a (stobjs::i obs-sdom-array$a) (declare (xargs :guard (obs-sdom-array$ap obs-sdom-array$a))) (resize-list obs-sdom-array$a stobjs::i 't))
