Collecting the data from a list of entries and putting it in a file is
a useful operation that will be needed by other entry types. Put this into
a method in the Entry class.

Add some documentation about how to collect data for an entry type.

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.

Bintools can be missing, in which case binman continues operation but
reports an invalid image. Plumb in support for this and add tests for
entry types which use bintools.

Tweak some naming and comments to resolve these. Use WriteFile() to write
the file.

The compression functions are not actually used by patman, so we don't
need then in the tools module. Also we want to change them to use
bintools, which patman will not support.

Move these into a new comp_util module, within binman.

Support collecting the available bintools needed by an image, by
scanning the entries in the image.

Also add a command-line interface to access the basic bintool features,
such as listing the bintools and fetching them if needed.

Since this is a list of blobs, each blob should have the ability to be
faked, as with blob-ext. Update the Entry base class to set allow_fake
and use the base class in the section code also, so that this propagagtes
to blob-ext-list, which is not a section.

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,
such as Entry_blob_ext_list, are not subclasses of Entry_blob.
