Minor grammar correction along with making the term 'login banner'

The current logging always assumes the boot timeout has expired yet
there is a second reason we might have ended up in a position where no
login banner was found, that being a socket disconnect. Add logging
for the disconnect case and make the timeout expiration conditional on
the timeout being exhausted.

When debugging issues when timeouts are involved it is always best to
have wall clock times included. This helps give confidence that the
timeout is in fact run down at the right rate and that no unexpected
events were the true cause of a premature running down of the
timeout. Having these times in old logs also helps when debugging
issues as we have a historic record as to what is a 'typical' time to
complete an action.
In addition to adding the wall clock times the time to 'login' is now
printed making it consistent with the time to 'qemu pid'.

I have concerns that bad timing of the flow of data from the logger
might corrupt the output due to the way binary strings are handled
in qemurunner.
This simplifies the code to do the same thing it did before but much
more safely.

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.

There are cases where the 'while loop' waiting for login prompt fails
and the bootlog variable does not get populated, thus use the the new
qemurunner member (self.msg) which stores all output coming from the qemu
process.

We need QEMU PID in order to access "/proc/<qemupid>/cmdline"
Having a valid QEMU PID does not mean we can access the proc entry
immediately, we need to wait for the /proc/<qemupid> to appear

Python unittest intercepts stdout and stderr however qemurunner sets
up a streamhandler before that interception occurs, hence the messages
spam the unittest output.
By moving the logging init to the class init time, we use the unittest
stdout/stderr and this means unittest can only show the log output upon
failure. This cleans up the selftest and testimage output whilst still
showing logging upon failure.

We're seeing timeouts in the autobuilder testing code. Increase these

That a utility function permanently changes the process environment is
bad style and leads to subtle, hard to debug problems.
For example, we had one oe-selftest which used runqemu() with an
override for DEPLOY_DIR_IMAGE. Another test then just called runCmd()
and ended up passing the wrong DEPLOY_DIR_IMAGE set earlier in
os.environ.
The approach used here is to pass the desired environment dict to the
launch() method as a new, optional parameter, which then gets passed
on to subproject.Popen(). The modified env variables do not get
logged, as before.

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.

Rather than copying images, use the snapshot option to qemu. This fixes a regression
caused by the recent runqemu changes where the wrong images were being testes since
the image is copied without the qemuboot.conf file. This means the latest image is
found by runqemu rather than the specified one, leading to various confused testing
results.
It could be fixed by copying more files but use snapshot mode instead.

QemuRunner requires pair of ip addresses provided through kernel
commandline for method 'start' to work. These ip addresses are
used to connect to the image using ssh and run tests there.
However, this functionality should not be mandatory as testing
doesn't always require ssh connection. Some tests can be run using
serial console.
Added new parameter 'get_ip' to QemuRunner.start to make it possible
to skip getting pair of ip addresses from kernel command line. This
should allow oe-selftest to test images without modifying kernel
command line.

Sometmes when there is high load in the server the
commands executed in the target take a lot of time
to complete and this lead to incorrect dump files or
empty files. This is caused because run_serial has a
timeout of five seconds when running the commands in
the target.
This change removes the timeout and just keep reading
the socket until it finds the prompt from the target
or when the socket is not ready to be read.

Currently the output from qemu could contain control
or Unicode characters; having such characters in the
log will cause an internal server error when sending
the report to error reporting web. Control characters
can be found in the command line used to run quemu too.
This change sanitize the output from qemu and the
command line used to run qemu, this way the logs doesn't
contain control or Unicode characters and this will solve
the issue of error reporting web and generate better
logs.
The only Unicode character found in the qemu output
is the copyright symbol, it really doesn't interfer
removing Unicode characters with debugging.

Currently, if qemu segfaults, the tests merrily continue trying to execute
which takes time for them to timeout and is a bit silly. Worse, no logs about
the segfault are shown to the user, its silent!
This patch tries to unravel the tangled web of issues and ensures that we:
* install a SIGCHLD handler which tells the user qemu exited
* check if qemu is running, if it isn't fail the test outright
* don't leave processes behind in sshcontrol which would hold
bitbake.lock and block shutdown
