See the next patches and how virtio-mem will make use of the feactored 
out functions. Not putting them as inline functions into a header will 
require exporting symbols just do add a vmcore memory node to the list, 
which I want to avoid -- overkill for these simple helpers.

I chose "vmcore_mem_node" because it is a memory range stored in a list. 
Note the symmetry with "vmcoredd_node"

If there are strong feelings I can use a different name, but 
"vmcore_mem_node" really describes what it actually is. Especially now 
that we have different vmcore nodes.
