Finds the memory blocks that span size bytes starting from offset in this.
When this function returns true, idx will contain the index of the first memory block
where the byte for offset can be found and length contains the number of memory blocks containing the size
remaining bytes. skip contains the number of bytes to skip in the memory block at idx to get to the byte
for offset.
size can be -1 to get all the memory blocks after idx.
