Runtime tests running on test runners are subject to a high
variability in term of performance and timing. Most or the runtime
test commands are executed with a timeout, in pexpect.
Slow or very loaded test runners can use the timeout_multiplier to
globally increase those timeouts.
Some runtime test commands sometimes needs to poll or query a state,
rather than having purely sequential actions. It is sometimes hard to
know, from the test writer point of view, the maximum timeout to set, or
if a retry logic is needed.
In order to help debugging runtime tests failing due very slow
execution, this commit adds extra information on the host test runner
about its load in the run log. Relevant information are: number of
cpus, the load average at the moment the emulator is started and the
current timeout_multiplier.

s6-test was removed in s6-portable-utils 2.3.0.0, and replaced with
eltest (from execline). This change broke the existing runtime tests
with commit 42fad03182 ("packages: bump skalibs-related packages").
Instead of s6-test simply use the shell built-in "test", which provides
sufficient functionality.

The TestInitSystemNone bypasses the normal init and instead launches
directly into a shell. So it needs to bypass the login code and go
directly to a shell.

This test started failing at commit
0cad947b96
"support/testing/infra/emulator.py: fix qemu prompt detection" with the
error message
AttributeError: 'NoneType' object has no attribute 'run_command'
This is because we changed emulator.run() so that emulator.login() must
be called first. But this test skips the login and goes directly to a
shell. Use the new emulator.connect_shell() function which prepares the
shell without logging in.

Since we copied a piece from code from pexpect, we need to also follow
the license of pexpect. Effectively, that makes the file licensed under
both our default GPL-2.0 and pexpect's ISC license. This is already
hinted at in the comment inside _repl_sh_child, but let's make it
explicit by adding a license header to the file.
Ideally, of course, each file in Buildroot would have a license file.
This was done with the reuse tool:
reuse annotate -l GPL-2.0 -l ISC support/testing/infra/emulator.py

The qemu.run() method can break when a command happens to output the
string "# " to stdout. This is because qemu.run() detects when a command
has completed by searching for the shell prompt, which by default is
"# ". It then captures everything before the "# " as the commands
output, causing the rest of output to be lost.
Instead use the pexpect libraries REPLWrapper to handle running
commands. It has hooks to set a custom prompt and avoid some other
pitfalls of wrapping a shell.
We unfortunately can't reuse replwrap._repl_sh directly, because it
tries to spawn a command while we already have a qemu started. So we
need to copy that code into _repl_sh_child. While we're at it, also
define our own prompt strings.

- Make all arguments to _repl_sh_spawn non-optional.
- Move non_printable_insert to a local variable instead of an argument,
we don't need to override it.
- Copy the comment from _repl_sh that explains why non_printable_insert
is needed.
- Add a comment about timeouts.
- Rename spawn to child (we don't actually spawn anything so this felt
more natural, even though the class
- Use single quotes instead of triple quotes, and explicitly escape the
nested quotes.

The python-pymupdf and mupdf packages do not follow the exact same
version numbers anymore. There is no specific mention of version
compatibilities in the upstream package, so update our comment to just
say that both should be "compatible" (to try to avoid one being
updated without the other).
The hardcoded paths we used to remove from setup.py are no longer
present, so the post-patch hook is removed. The new setup.py instead
uses new environment variables which we now provide.
This new python-pymupdf version fails at runtime when mupdf builds
static libraries.
Note also that python-pymupdf is gradually switching to a new
implementation that requires mupdf to be built with python
bindings. For now, both implementations are still available but we
only compile the old one. The runtime test is adapted accordingly as
the legacy implementation has to be imported with "fitz_old".
While at it, the dependencies are also split to one per line to make
them easier to diff in the future.

To give us a chance to catch runtime issues (such as missing
dependencies) more easily, add a test that writes a sample PDF file,
read it back and verify the text that was read.
Like similar packages that lead to a big
rootfs (e.g. python-botocore), this test requires a separate ext2
rootfs to avoid filling the default amount of RAM available
entirely (which would cause missing files from the root filesystem and
in turn, test failures).

Version 2.1.0 is a major bump, with an API change that should be
backward compatible with version up to 1.6.1.
The runtime test failed in timeout because the crng init did not have
time to complete in the default 5-second timeout; tests showed that the
trip-off would be between 6s and 7s here, so increase it enough to leave
some margin on less-capable machines.

The python-magic-wormhole runtime test can randomly fail on slow
runners, see [1].
The issue is that the sending command is started first in background
_without_ redirecting its output to /dev/null. The receiving command
is started after, expecting the message to be printed on the first
standard output line. On slower systems, the sending command still
print messages while the test controller expect output from the
receiving command. The expected string finally appear, but not on the
first line. This makes the test fail.
This commit fixes the issue by redirecting all outputs (stdout, stderr)
of the sending command to /dev/null. To help even more, the sleep time
is moved from the emulator to the test controller. The sleep time is
also multiplied by the timeout_multiplier.
