Explicit Feedback on Layout Change

With [1b94560] push an Advanced Policy comes with a verbose build steps.
Now after modifying a source the build process informs about what has changed in *.ld layout since previous build (this is planned to be changed and compared against previous memory content, not previous build as not every build is programmed into memory).

From there it should be quite easy to provide a more descriptive way of what has been changed and why some modifications cause ROM content change (and impose time-consuming reflashing).

Current implementation informs only about the layout change (informs about change of the location of some resource in memory). However there is no information given about the change of the resource as such so far.

• if we make a resource move from ROM to RAM then that is indicated
• if we change only the size of the resource then that is not indicated

in the build report.

This is on my todo list.

Works great!
