Once binman has packed the image, the position and size of each entry is
known. It is then possible for binman to update the device tree with these
positions. Since placeholder values have been added, this does not affect
the size of the device tree and therefore the packing does not need to be
performed again.
Add a new SetCalculatedProperties method to handle this.

Some entry types modify the device tree, e.g. to remove microcode or add a
property. So far this just modifies their local copy and does not affect
a 'shared' device tree.
Rather than doing this modification in the ObtainContents() method, and a
new ProcessFdt() method which is specifically designed to modify this
shared device tree.
Move the existing device-tree code over to use this method, reducing
ObtainContents() to the goal of just obtaining the contents without any
processing, even for device tree.

This method is supposed to return the contents of an entry. However at
present there is no check that it actually does. Also some implementations
do not return 'True' to indicate success, as required.
Add a check for things working as expected, and correct the
implementations.
This requires some additional test cases to cover things which were missed
originally. Add these at the same time.

Sometimes we have several sections which repeat the same entries (e.g. for
a read-only and read-write version of the same section). It is useful to
be able to tell these entries apart by name.
Add a new 'name-prefix' property for sections, which causes all entries
within that section to have a given name prefix.

It is useful to be able to see a list of regions in each image produced by
binman. Add a -m option to output this information in a '.map' file
alongside the image file.

It is useful to be able to split an image into multiple sections,
each with its own size and position, for cases where a flash device has
read-only and read-write portions.
Add support for this.

We want to support multiple sections within a single image. To do this,
move most of the Image class implementation into a new Section class. An
Image contains only a single Section, but at some point we will support
a new 'section' entry, thus allowing Sections within Sections.
Use the name 'bsection' for the module so we can use 'section' for the
etype module.
