These are similar to the existing FF_ALLOC_ARRAY_OR_GOTO &
FF_ALLOCZ_ARRAY_OR_GOTO,
but the elsize is calcuated by sizeof(*p)

This should not duplicate functionality of FF_ALLOC_ARRAY_OR_GOTO, but it
should be defined as
FF_ALLOC_ARRAY_OR_GOTO(ctx, p, nelem, sizeof(*(p)), label)
+{\
+ p = av_malloc_array(nelem, sizeof(*p));\
+ if (!p) {\
+ av_log(ctx, AV_LOG_ERROR, "Cannot allocate memory.\n");\

Same here
