buildhistory: record additional image info

Record some additional information about images - the uncompressed size
of the final image as well as the values of various variables that may
have influenced its contents. This is recorded in a machine-readable
"image-info.txt" file similar in structure to the package history files.

Also add some code to analyse changes to these values. (Most of the
variable values aren't monitored directly but will be used as contextual
information when they change at the same time as the content of the
image changing.)
