The console interaction that waits for predicted strings uses
readline(), and thus is only capable of waiting for strings
that are followed by a newline.
This is inconvenient when needing to match on some things,
particularly login prompts, or shell prompts, causing tests
to use time.sleep(...) instead, which is unreliable.
Switch to reading the console 1 byte at a time, comparing
against the success/failure messages until we see a match,
regardless of whether a newline is encountered.
The success/failure comparisons are done with the python bytes
type, rather than strings, to avoid the problem of needing to
decode partially received multibyte utf8 characters.
Heavily inspired by a patch proposed by Cédric, but written
again to work in bytes, rather than strings.

When waiting for expected output, the 'success_message' is a mandatory
parameter, with 'failure_message' defaulting to None.
The code has logic which indicates it was trying to cope with
'success_message' being None and 'failure_message' being non-None but
it does not appear able to actually do anything useful. The check for
'success_message is None' will break out of the loop before any check
for 'failure_message' has been performed.
IOW, for practcal purposes 'success_message' must be non-None unless
'send_string' is set. Assert this expectation and simplify the loop
logic.

When functional tests go wrong, it will often be related to the console
interaction wait state. By logging the messages that we're looking for,
and data we're about to be sending, it'll be easier to diagnose where
tests are getting stuck.

has_cmd returns a tuple, not a boolean value. This fixes a crash when
e.g. "tesseract" is not available in the test_m68k_nextcube test.

Straight forward conversion. Update the SHA1 hash to
SHA256 since SHA1 should not be used anymore nowadays.
Provide get_qemu_img() helper in qemu_test.

The files are mostly a copy of the tests/avocado/avocado_qemu/__init__.py
file with some adjustments to get rid of the Avocado dependencies (i.e.
we also have to drop the LinuxSSHMixIn and LinuxTest for now).
The emulator binary and build directory are now passed via
environment variables that will be set via meson.build later.
