convert 53 malloc(a*b) to reallocarray(NULL, a, b). that is 53

potential integer overflows easily changed into an allocation return
of NULL, with errno nicely set if need be.  checks for an allocations
returning NULL are commonplace, or if the object is dereferenced
(quite normal) will result in a nice fault which can be detected &
repaired properly.
