Where there isn't a copyright statement, add one to make it explicit.
Also drop editor config lines where they were present and add license
identifiers as MIT if there isn't one.

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.

The 'task-time' Python script is used for simple manual analysis of
buildstats. It displays task timing information in the same format (and
using the same calculation) as the Bash 'time' builtin, and can
optionally sort tasks by real (wall-clock), user (user space CPU), or
sys (kernel CPU) time used.
The timing information comes from the getrusage(2) fields added by
commit adfdca4df1 ("buildstats: Improve to add getrusage data and
corrected IO stats"). That commit is required for the script to work.
Example 1: Running 'task-time' on a specific task buildstat:
$ task-time ./20161005235448/gettext-0.16.1-r6/do_compile
./20161005235448/gettext-0.16.1-r6/do_compile:
real 0m54.560s
user 0m46.028s
sys 0m2.772s
Example 2: Running 'task-time' on a directory, sorting on wall-clock
time:
$ task-time tmp/buildstats/20161018083535 --sort real
tmp/buildstats/20161018083535/bash-4.3.30-r0/do_fetch:
real 10m59.140s
user 0m1.152s
sys 0m0.320s
tmp/buildstats/20161018083535/readline-native-6.3-r0/do_fetch:
real 8m57.310s
user 0m0.860s
sys 0m0.288s
tmp/buildstats/20161018083535/perl-5.22.1-r0/do_compile:
real 4m28.840s
user 4m1.348s
sys 0m15.816s
...
Example 3: Running 'task-time' on all do_compile buildstats for a
particular build by using shell globbing, sorting on user space CPU
time:
$ task-time tmp/buildstats/20161018083535/*/do_compile --sort user
tmp/buildstats/20161018083535/qemu-native-2.7.0-r1/do_compile:
real 0m49.570s
user 21m45.236s
sys 1m44.380s
tmp/buildstats/20161018083535/linux-yocto-4.8+gitAUTOINC+03bf3dd731_67813e7efa-r0/do_compile:
real 0m49.530s
user 21m39.588s
sys 1m59.576s
tmp/buildstats/20161018083535/gcc-cross-i586-6.2.0-r0/do_compile:
real 1m8.130s
user 15m54.256s
sys 1m28.776s
...
Example 4: Comparing a task between two builds:
$ task-time 201610052{25856,35448}/gettext-0*/do_compile --sort real
20161005235448/gettext-0.16.1-r6/do_compile:
real 0m54.560s
user 0m46.028s
sys 0m2.772s
20161005225856/gettext-0.19.8.1-r0/do_compile:
real 0m41.520s
user 2m17.312s
sys 0m7.536s
