Given a 'buildstats' path (created by bitbake when setting
USER_CLASSES ?= "buildstats" on local.conf) and task names, outputs
'<task> <recipe> <elapsed time>' for all recipes. Elapsed times are in
seconds, and task should be given without the 'do_' prefix.
Some useful pipelines
1. Tasks with largest elapsed times
$ buildstats.sh -b <buildstats> | sort -k3 -n -r | head
do_compile perl-5.20.0-r1 221.82
do_configure gettext-native-0.19.4-r0 140.34

do_compile openssl-1.0.2a-r0 102.10

do_compile qemu-native-2.2.0-r1 71.69
do_compile glibc-2.21-r0 60.88
2. Min, max, sum per task
$ buildstats.sh | datamash -t' ' -g1 min 3 max 3 sum 3 | sort -k4 -n -r

If not every combination of BB_NUMBER_THREADS and PARALLEL_MAKE have
been tested by bb-matrix.sh, e.g., by using BB_RANGE="04 08 10 12 16"
and PM_RANGE="04 08 10 12 16", then the graph that gnuplot generates by
default looks very jagged due to the missing data points. By using
splines to interpolate the missing data the graph looks a lot better.
This should not change graphs where all data points are available in any
way, only improve sparse graphs.

This makes sure the the first build starts from a clean state. Otherwise
one could have the first build affected by any leftover state from
a previous build.
This also leaves a working state behind after the final build.

The BB and PM ranges were originally intended to use leading 0s to
ensure all the values were the same string length, making for nice log
filenames and columnar dat files. However, not everyone will do this -
especially if it isn't documented.
Document the intent. Make the generation and parsing of dat files robust
to either method.

The bash string operation ${BB##*0} was greedy and in addition to converting
"02" to "2", also converted "20" to "", causing all builds for a BB value ending
in 0 to run with BB_NUMBER_THREADS=1.

The bb-matrix.sh script will run a bitbake command, building core-image-minimal
by default, for various combinations of BB_NUMBER_THREADS and PARALLEL_MAKE. It
records all relevant metrics of the TIME(1) command for each combination in a
data file.
The bb-matrix-plot.sh script can be used to visualize each of these metrics via
a 3d surface plot, either solid surface or wireframe with a value-map
projection on the XY plane.
