We have a working theory that IO queues on the autobuilder are impacting
runtime testing under qemu, particularly async writes which inice does not
influence. We already pass the snapshot option to qemu which copies the
image and runs out of the copy. Add in the ability to copy the image to
a specificed location which can be a tmpfs. This means that writes to the
image would no longer be blocked by other writes to disk in the system.
Preliminary tests show that this does improve the qemu errors at the expense
of sometimes showing qemu startup timeouts as on a loaded system with a large
test image, it can take longer than 120s to copy the image to tmpfs. Having
a most consistent failure mode for loaded tests is probably desireable though.

We're seeing failures due to system load. In theory we've set process
nice levels which should compensate for this. Add debugging so we can
find out if they're being correctly applied.

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 5s timeout for non-kvm is too short, especially when the load is high,
which leads to unexpected errors, so set timeout to 60s by default.

The logger handling in oeqa was confused at best. This patch:
a) Passes in a logger through various qemu runner pieces
b) Uses that logger consistently in the code
c) Creates a logger for QemuRunner outside the bitbake namespace
meaning we don't conflict with the tinfoil logging changes
The result of this is more consistency. For runtime tests in testimage,
the logs always contain the debug info, nothing is shwon on the console.
For the oe-selftests, logs are intercepted and only shown if the test
fails.

By default, QemuRunner avoids modifying the image files that it boots
into by enabling the qemu snapshot mode. However, some tests may want
to test changes that must persists across reboots, so this mode
should be optional.
This can be combined by copying the image file to a temporary location
first and then booting with that copy. It's also useful when testing
with additional drives attached to a virtual machine.
QemuTinyRunner doesn't use the snapshot parameter and therefore ignores
the new parameter.
Long term, a better way of passing these various configuration
parameters should be used, and perhaps QemuRunner and QemuTinyRunner
can be merged into one again to avoid code duplication. But for now
the patch follows the exiting style.
Also beware that QemuTarget.start() now acts in two different modes
(with or without explicit launch command), and depending on that mode
parameters like discard_writes must be ignored, i.e. not get passed to
launch().

Sometimes, the OEQA utility code aborts with:
...
File ".../meta/lib/oeqa/utils/qemurunner.py", line 131, in start
return self.launch(launch_cmd, qemuparams=qemuparams, get_ip=get_ip, extra_bootparams=extra_bootparams)
File ".../meta/lib/oeqa/utils/qemurunner.py", line 259, in launch
sread, swrite, serror = select.select(socklist, [], [], 5)
InterruptedError: [Errno 4] Interrupted system call
strace shows that this is because of a SIGWINCH:
Connection from 127.0.0.1:52668
select(21, [20], [], [], {5, 0}) = ? ERESTARTNOHAND (To be restarted if no handler)
--- SIGWINCH {si_signo=SIGWINCH, si_code=SI_KERNEL} ---
This is related to some special conditions:
* whether qemu opens a graphical console window (enabled in Poky by default)
* where that window gets opened
* whether the window manager changes the size of the shell window (mine
is a tiling window manager and reorders and resizes windows automatically)
Ignoring the interrupted system calls avoids the problem. Code elsewhere (for example,
run() in ssh.py) already does the same thing.

Some commands might need to run longer than the default timeout of
five seconds. If that occurred, run_serial() returned with a status
code of zero (sic!) and no other indication of what went wrong.
Now the timeout is configurable (with five still the default) and
an explicit warning ("<<< run_serial(): command timed out after 5 seconds without output >>>")
gets appended at the end of the data returned to the caller.
While at it, the logic for checking for the timeout was updated a bit
because both implementations could overshoot the timeout when entering
select() right before the final deadline.

Added possibility to pass additional runqemu parameters
down the stack of APIs:
commands.runqemu -> QemuTarget.start -> QemuRunner.start
This will be used to pass ovmf parameter in testing of
efi wic images under qemu.

In python3, strings are unicode by default. We need to encode/decode
from command pipelines and other places where we interface with the
real world using the correct locales. This patch updates various
