Add a link to binman's documentation and adjust the files so that it is
accessible. Use the name README.rst so it is easy to discover when binman
is installed without U-Boot.

Add support for this feature in the control, image and section modules, so
that expanded entries will be selected by default. So far there are no
expanded entry types, so this is a nop.

Extracting files to the current directory is not normally a very friendly
thing to do, but it can be warranted, e.g. in a new temporary dir. At
present binman reports an error when such an attempt is made. Fix it.

Update the log output to show the size, since this is useful information.

This method introduces a separation between packing and checking that is
different for sections. In order to handle compression properly, we need
to be able to deal with a section's size being smaller than the
uncompressed size of its contents. It is easier to make this work if
everything happens in the Pack() method.

The only real user of CheckEntries() is entry_Section and it can call it
directly. Drop the call from 'control' and handle it locally.

This is only used by entry_Section and that class already calls it. Avoid
calling it twice. Also drop it from the documentation.

When a section is compressed, all entries within it are grouped together
into a compressed block of data. This obscures the start of each
individual child entry.

Avoid reporting bogus 'image-pos' properties in this case, since it is
not possible to access the entry at the location provided. The entire
section must be decompressed first.

CBFS does not support compressing whole sections, only individual files,
so needs no special handling here.

When an external blob is missing it can be quite confusing for the user.
Add a way to provide a help message that is shown.

Tidy up a few test functions which lack argument comments. Rename one that
has the same name as a different test.

Also fix up the comment for PrepareImagesAndDtbs().

At present we look for resources based on the path of the Python module
that wants them. Instead we should use Python's pkg_resources feature
which is designed for this purpose.

Update binman to use this.
