In the past kernel built object files were named 'built-in.o'.
Nowadays it is 'built-in.a'.
The script is modified to work with both. I expect
it will not happen that there are built-in.a and built-in.o
files in the same kernel.

Although the script was running with Python3, almost no detailed
output was generated.

This adds SPDX license headers in place of the wide assortment of things
currently in our script headers. We default to GPL-2.0-only except for the
oeqa code where it was clearly submitted and marked as MIT on the most part
or some scripts which had the "or later" GPL versioning.
The patch also drops other obsolete bits of file headers where they were
encoountered such as editor modelines, obsolete maintainer information or
the phrase "All rights reserved" which is now obsolete and not required in
copyright headers (in this case its actually confusing for licensing as all
rights were not reserved).
More work is needed for OE-Core but this takes care of the bulk of the scripts
and meta/lib directories.
The top level LICENSE files are tweaked to match the new structure and the
SPDX naming.

'ksum.py' generates a combined summary of vmlinux and module sizes for
a built kernel, as a quick tool for comparing the overall effects of
systemic tinification changes. Execute from the base directory of the
kernel build you want to summarize. Setting the 'verbose' flag will
display the sizes for each file included in the summary.

Python 3 ignores the __cmp__() method and doesn't have cmp() builtin
function. This caused sorted() call to raise
TypeError: unorderable types: Record() < Record()
Removing __cmp__ method and implementing __lt__ should solve the
problem as __lt__ is the only method needed for sort[ed] to work.

Used join method instead of strings.join as stings.join
doesn't exist in python 3.

Changed old syle except statements 'except <exception>, var'
to new style 'except <exception> as var' as old style is not
supported in python3.

Fixes [YOCTO #5388]
These scripts can be useful when working to reduce the size of the Linux
kernel and the root filesystem.
ksize.py displays the kernel build size by the built-in.o files.
dirsize.py displays the various sizes of the components of the root
directory.
