Use the new logging feature to log information about progress with
packing. This is useful to see how binman is figuring things out.
Also update elf.py to use the same feature.

This tool has quite a few arguments and options, so put the functionality
in a function so that we call it from one place and hopefully get it
right.

Add utility functions to compress and decompress using lz4 and lzma
algorithms. In the latter case these use the legacy lzma support favoured
by coreboot's CBFS.
No tests are provided as these functions will be tested by the CBFS
tests in a separate patch.

While reading files in binary mode is the norm, sometimes we want to use
text mode. Add an optional parameter to handle this.

In Python 3 bytes and str are separate types. Use bytes to ensure that
the code functions correctly with Python 3.

The difference between the bytes and str types in Python 3 requires a
number of minor changes to this function. Update it to handle the input
data using the 'bytes' type. Create two useful helper functions which can
be used by other modules too.

Create helper functions in the tools module to deal with the differences
between unicode in Python 2 (where we use the 'unicode' type) and Python 3
(where we use the 'str' type).

The method of multiplying a character by a number works well for creating
a repeated string in Python 2. But in Python 3 we need to use bytes()
instead, to avoid unicode problems, since 'bytes' is no-longer just an
alias of 'str'.
Create a function to handle this detail and call it from the relevant
places in binman.

At present cros_subprocess and the tools library use a string to obtain
stdout from a program. This works fine on Python 2. With Python 3 we end
up with unicode errors in some cases. Fix this by providing a binary mode,
which returns the data as bytes() instead of a string.

In some cases it is useful to add a group of files to the image and be
able to access them at run-time. Of course it is possible to generate
the binman config file with a set of blobs each with a filename. But for
convenience, add an entry type which can do this.
Add required support (for adding nodes and string properties) into the
state module.

When tools are needed but not present, at present we just get an error
which can be confusing for the user. Try to be helpful by reporting the
tool as missing and suggesting a possible remedy.
Also update the Run() method to support this.

When this fails it is useful to see the current directory, since U-Boot's
build system will typically change into the output directory during the
build. Add this information to the error.

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.

For tools which want to use input files and temporary output, it is useful
to have the handling of these dealt with in one place. Add a new library
which allows input files to be read, and output files to be written, all
based on a common directory structure.
