When an image has the 'allow-repack' property, binman includes the
original offset and size properties from the image description in the
fdtmap. These are later used as the packing constraints when replacing
entries in an image, so other unconstrained entries can be freely
positioned.
Replacing an entry in an image without 'allow-repack' (and therefore the
original offsets) follows the same logic and results in entries being
merely concatenated. Instead, skip resetting the calculated offsets and
sizes to the missing originals for these images so that every entry is
constrained to its existing offset/size.
Add tests that replace an entry with smaller or equal-sized data, in an
image that doesn't allow repacking. Attempting to do so with bigger-size
data is already an error that is already being tested.

Binman entries can use other executables to compute their data, usually
in their ObtainContents() methods. Subclasses of Entry_section would use
bintools in their BuildSectionData() method instead, which is called
from several places including their Pack().
These binary tools are resolved correctly while building an image from a
device-tree description so that they can be used from these methods.
However, this is not being done when replacing entries in an image,
which can result in an error as the Pack() methods attempt to use them.
Collect and resolve entries' bintools also when replacing entries to fix
Pack() errors. Add a way to mock bintool usage in the testing entry type
and tests that check bintools are being resolved for such an entry.

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.

While converting to binman for an imx8mq board, it has been found that
building in the u-boot CI fails. This is because an imx8mq requires an
external binary (signed_hdmi_imx8m.bin). If this file cannot be found
mkimage fails.
To be able to build this board in the u-boot CI a binman option
(--fake-ext-blobs) is introduced that can be switched on via the u-boot
makefile option BINMAN_FAKE_EXT_BLOBS. With that the needed dummy files are
created.

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.

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.

At present the symbol information is written to binaries just before

contents is calculated when it is needed, so the updated symbol values are

their contents and do not notice that the entries have changed (e.g. Intel
IFWI).

At present binman cannot replace data within a CBFS since it does not
allow rewriting of the files in that CBFS. Implement this by using the
new WriteData() method to handle the case.
Add a header to compressed data so that the amount of compressed data can
be determined without reference to the size of the containing entry. This
allows the entry to be larger that the contents, without causing errors in
decompression. This is necessary to cope with a compressed device tree
being updated in such a way that it shrinks after the entry size is
already set (an obscure case). It is not used with CBFS since it has its
own metadata for this. Increase the number of passes allowed to resolve
the position of entries, to handle this case.
Add a test for this new logic.
