9722381c0d scripts/graph-build-time: properly warn about missing modules
Currently the graph-build-time script prints a python exception if a
needed module cannot be imported. Catch the exception and tell the user
which packages are missing, as we do for other missing dependencies.

96183af9af scripts/graph-build-time: clarify backend selection
This instruction in the middle of 'import' lines looks very strange.

Also, it was not obvious to me what the 'Agg' backend is.

Both things are actually correct, but it took a while to find out why.
So clarify with a comment to save someone else's time.

[Peter: fix s/soe/some/ typo]

a89f14e0f1 support/graphs: fix comparisons agains None
As Samuel said:
    In Python, None is a singleton, and it is recommended to use "is" or
    "is not" for testing them [1].

ef8b8d950f graphs: make graphs with lots of packages nicer to look at
Some magic numbers obtained with trial-and-error and successive
iterations, to eventually get a nice graph.

[Thomas: remove excessive spaces in expressions.]

f1fedbb246 graphs: support generating png graphs
PDF files can not be easily embedded in other documents (eg. ODT, or HTML).

Add support for generating PNG graphs, by setting the GRAPH_OUT=pdf|png on
the command line:
    make GRAPH_OUT=png graph-build graph-depends

The default is still to generate PDF graphs.

7d656636bd graph-build-time: generate graphs based on timing data
This script generates graphs of packages build time, from the timing
data generated by Buildroot in the $(O)/build-time.log file.

Example usage:

  ./support/scripts/graph-build-time \
      --type=histogram --input=$(O)/build-time.log --output=foobar.pdf

Three graph types are available :

  * histogram, which creates an histogram of the build time for each
    package, decomposed by each step (extract, patch, configure,
    etc.). The order in which the packages are shown is
    configurable: by package name, by build order, or by duration
    order. See the --order option.

  * pie-packages, which creates a pie chart of the build time of
    each package (without decomposition in steps). Packages that
    contributed to less than 1% of the overall build time are all
    grouped together in an "Other" entry.

  * pie-steps, which creates a pie chart of the time spent globally
    on each step (extract, patch, configure, etc...)

The default is to generate an histogram ordered by package name.

[yann.morin.1998@free.fr: adapt to the format of the step-hooks build-time.log,
    add sort order by name, default to name-ordered histogram, use our colours
    for pie-charts, add alternate color-scheme, add short-options, add
    --input/-i]
