...instead of GNU binutils to extract DWARF information.
This is now a bit more portable across OS and toolchain.
One bouns is that this nows with on qemu_x86_64.
A few differences are:
() z_mrsh_* which are aliases to handler_no_syscalls() are now
dropped as they are mapped to the same address, so that they
are not counted multiple times.
() Static functions and variables with same names should now be
attributed to the correct source files instead of being
accumulated into the same symbol of one file (e.g. multiple
thread_entry() in kernel tests).
() The totals for ROM and RAM are calculated from the
corresponding sections. Previous script includes the debug
sections as total ROM size which is not entirely correct.

- Remove unused variables and an unused 'sys' import
- Simplify 'if len(foo) != 0' to 'if foo'. Non-empty lists/dicts/etc.
are truthy in Python.
- Use a raw string to fix this warning:
scripts/footprint/size_report:270:0: W1401: Anomalous backslash
in string: '\.'. String constant might be missing an r prefix.
(anomalous-backslash-in-string)
The issue is that '\.' just happens to work due to not being
recognized as an escape sequence.
Escape sequences are not interpreted in raw strings, so they're safer
for regexes.
- Replace 'is 0' with '== 0'. 'is' is for testing object identity, and
0 isn't guaranteed to be a unique object (but always is in practice).

When stripped symbols are present in the build size_report has crashed
due to it not being aware of this case.
This patch causes stripped symbols to be ignored instead, allowing
analysis of the non-stripped symbols.
It is left as future work to somehow display how much space stripped
symbols are taking up.
Stripped symbols can be present when third-party binaries are linked
into the build.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

Was apparently an artifact of Python2 to Python3 conversion. Led to
printing of literal '='*110i instead of a line of ='s.

We first check to see if we have a valid elf file before doing anything
else. Otherwise we'd could get script errors instead of just notifying
the user the file doesn't exist.

We need a minimum of --outdir, --objdump, and --nm set for the script to
work so mark these arguments as required.

Do a straight forward conversion from optparse to argparser. All

Instead of crashing when a source file outside of ZEPHYR_BASE is

Some boards do not generate .bin files by default, this file is however
needed when generating ram/rom reports, so in case it is not present,
create it.

size_report was assuming Unix-style absolute paths and misbehaving
when paths had a colon ("C:\") in them. Also, refactored and improved
documentation.

Use Universal newlines when calling check_output and rely on the
locale's encoding to decode the output instead of explicitly decoding
UTF-8.

size_report was assuming that the GNU Binutils programs were
generating files with the line ending '\n'. But on native Windows
binutils will generate files with the line ending \r\n.
This patches size_report to use so-called "Universal newlines"[0], so
that size_report can deal with any kind of newline on any kind of
platform.

size_report was using the environment variables NM and OBJDUMP to find
it's toolchain dependencies. It is not clear how well this will work
on different platforms; OSX, Windows. So we now pass the paths of
these dependencies from the build system to the script.
PS: This ensures that size_report uses the cross-compiler's GNU bin
tool instead of the host GNU bin tools. This is presumably beneficial
as it has been required for other GNU bin tools like GDB.
