a3f37c53d5 support/scripts: sort pie charts
Make sure that the pie charts produced by 'graph-build' and 'graph-size'
targets are sorted on the size of each piece of the pie. Otherwise, making
visual analysis is difficult, as one needs to look at the legends of each
piece and do the sorting manually in their head.

88af7d330d support/scripts/size-stats: avoid divide-by-zero
Some packages (ex: skeleton-init-systemd) have a zero size so we cannot
divide by the package size. In that case make their percent zero
explicitly and avoid a ZeroDivisionError exception.

2ec0a7d11c size-stats: don't count hard links
This change adds inode tracking to the size-stats script so that hard
links don't cause files to be double counted. This has a significant
effect on the size computation for some packages. For example, git has
around a dozen hard links to a large file. Before this change, git would
weigh in at about 170 MB with the total filesystem size reported as
175 MB. The actual rootfs.ext2 size was around 16 MB. With the change,
the git package registers at 10.5 MB with a total filesystem size of
15.8 MB.

34b1bdeba4 size-stats: fix bug when parsing file names with comma
The size-stats script fails when the usb_modeswitch_data is enabled,
because this package installs files that contain commas in their
name. However, the size-stats script also uses comma as a separator for
its CSV files, causing a "ValueError: too many values to unpack" in:

  pkg, fpath = l.split(",")

Fix this by splitting only the two fields that need to be split.

The bug was reported by Matthias <porto.rio@gmx.net>, who also suggested
a fix.

Fixes bug #9136.

a059055c52 support/scripts/size-stats: fix copy/paste error in ArgumentParser
A copy/paste error in the ArgumentParser() constructor call disclosed
the fact that the author of the script has shamefully based his work
on the existing graph-build-time script. This commit fixes this
mistake, therefore hiding in a better way how size-stats was
vampirized from graph-build-time.

598c80be8f support/scripts: add size-stats script
This new script uses the data collected by the step_pkg_size
instrumentation hook to generate a pie chart of the size contribution
of each package to the target root filesystem, and two CSV files with
statistics about the package size and file size. To achieve this, it
looks at each file in $(TARGET_DIR), and using the
packages-file-list.txt information collected by the step_pkg_size
hook, it determines to which package the file belongs. It is therefore
able to give the size installed by each package.
