Add option to filter the stats results for a single recipe, allowing
to easilly visuality the task resource consumption per recipe.
This is specially useful when debugging the performance of
the overall bitbake build system.

Add option to accumulate stats values per recipe, allowing
to sum related values such as memory (main process + childs).
This is specially useful when debugging the performance of
the overall bitbake build system.

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.

There are many more stats on buildstats that 'Elapsed time', so make the script
more flexible to support all stats. Some cmd line examples:
$ buildstats.sh -s 'utime'
Buildstats' data covers proc's stats in different areas, including CPU times,
IO, program system resources and child program system resources. In order
to print values on each of these sets from command line, one can use the
following:
$ buildstats.sh -H -s 'TIME' | less
$ buildstats.sh -H -s 'IO' | less
and 'RUSAGE' and 'CHILD_RUSAGE' for program and program's child system
resources.

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-native-1.0.2a-r0 107.48
do_compile openssl-1.0.2a-r0 102.10
do_configure perl-native-5.20.0-r0 90.70
do_configure gettext-0.19.4-r0 88.17
do_compile gcc-cross-i586-4.9.2-r0 83.98
do_configure m4-native-1.4.17-r0 83.44
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
do_configure 0.03 140.34 1968.66
