Binman can embed a copy of the image description into the images it
builds as a fdtmap entry, but it omits the /binman/<image-name> prefix
from the node paths while doing so. When reading an already-built image
file, entries are reconstructed using this fdtmap and their associated
nodes still lack that prefix.
Some entries like fit and vblock create intermediate files whose names
are based on an entry unique name. This name is constructed from their
node's path by concatenating the parents with dots up to the binman
node, e.g. /binman/image/foo/bar becomes 'image.foo.bar'.
However, we don't have this /binman/image prefix when replacing entries
in such an image. The /foo/bar entry we read when doing so erroneously
has the unique name of '/.foo.bar', causing permission errors when the
entry attempts to create files based on that.
Fix the unique-name generation by stopping at the '/' node like how it
stops at the binman node. As the unique names are used as filenames, add
tests that check if they're safe to use as filenames.

Binman's FIT entry type can have image subentries with "hash" subnodes
intended to be processed by mkimage, but not binman. However, the Entry
class and any subclass that reuses its implementation tries to process
these unconditionally. This can lead to an error when boards specify
hash algorithms that binman doesn't support, but mkimage supports.
Let entries skip processing these "hash" subnodes based on an instance
variable, and set this instance variable for FIT subsections. Also
re-enable processing of calculated and missing properties of FIT entries
which was disabled to mitigate this issue.

Since this is a list of blobs, each blob should have the ability to be

At present binman writes fake blobs to the current directory. This is not
very helpful, since the files serve no useful purpose once binman has
finished. They clutter up the source directory and affect future runs,
since the files in the current directory are often used in preference to
those in the board directory.
To avoid these problems, write them to the output directory instead.
Move the file-creation code to the Entry base class, so it can be used by
any entry type that needs it. This is required since some entry types,

Generally the content of sections is not built until the final assembly
of the image. This is partly to avoid wasting time, since the entries
within sections may change multiple times as binman works through its
various stages. This works quite well since sections exist in a strict
hierarchy, so they can be processed in a depth-first manner.
However the 'collection' entry type does not have this luxury. If it
contains a section within its 'content' list, then it must produce the
section contents, if available. That section is typically a sibling
node, i.e. not part oc the collection's hierarchy.
Add a new 'required' argument to section.GetData() to support this. When
required is True, any referenced sections are immediately built. If this
is not possible (because one of the subentries does not have its data yet)
then an error is produced.
The test for this uses a 'collection' entry type, referencing a section as
its first member. This forces a call to _BuildSectionData() with required
set to False, at first, then True later, when the image is assembled.

Normally when an entry is created, any entry arguments it has are required
to be provided, so it can actually generate its contents correctly.
However when an existing image is read, Entry objects are created for each
of the entries in the image. This happens as part of the process of
reading the image into binman.
In this case we don't need the entry arguments, since we do not intend to
regenerate the entries, or at least not unless requested. So there is no
sense in reporting an error for missing entry arguments.
Add a new property for the Image to handle this case. Update the error
reporting to be conditional on this property.
