At present if libfdt is not available binman can't do anything much.
Improve the situation a little.
Ideally there should be a test to cover this, but I'm not quite sure how
to fake this.

(fixed up missing ReadChildData() enty test)
At present we simply extract the data directly from entries using the
image_pos information. This happens to work on current entry types, but
cannot work if the entry type encodes the data in some way. Update the
ReadData() method to provide the data by calling a new ReadChildData()
method in the parent. This allows the entry_Section class, or possibly
any other container class, to return the correct data in all cases.

It is useful to be able to extract entry contents from an image to see
what is inside. Add a simple function to read the contents of an entry,
decompressing it by default.

At present the logic skips the blob class' handling of compression, so
this is not supported with device tree entries. Fix this.

Compression is currently available only with blobs. However we want to
report the compression algorithm and uncompressed size for all entries,
so that other entry types can support compression. This will help with
the forthcoming 'list' feature which lists entries in the image.
Move the compression properties into the base class. Also fix up the docs
which had the wrong property name.

The lz4 utility inserts binary data in its output which cannot always be
converted to unicode (nor should it be). Fix this by using the new binary
mode for program output.

Add support for compressing blob entries. This can help reduce image sizes
for many types of data. It requires that the firmware be able to
decompress the data at run-time.

This function name is too generic for its purpose and is therefore
confusing. It actually only applies to blobs, so rename it to indicate
this.

At present only the more complex entries are documented. It is useful to
have documentation for all entries in one place.
As a first step, add and expand the documentation to cover all entries.

At present the contents of an entry are set in subclasses simply by
assigning to the data and content_size properties. Add some methods to do
this, so that we have more control. In particular, add a method to set the
contents without changing its size, so we can validate that case.
Add a test case for trying to change the size when this is not allowed.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Add entries to support some standard U-Boot binaries, such as u-boot.bin,
u-boot.dtb, etc. Also add some tests for these.
