When running multiple instances of emulator in parallel, the login
prompt can take some time to appear.
Use a large timeout when waiting for the prompt to avoid random
failures.

Remove unused import.
Use 2 empty lines before a class.

When using pexpect there is no need for a helper function. Just use
expect() directly everywhere.

When the parameter logfile is passed to spawn(), pexpect sends both
stdin and stdout to the logfile and it creates a double echo effect.
One way to avoid the double echo in the logfile would be to disable the
echo on the terminal just after login ("stty -echo"), but double echo of
user and password would remain.
Instead of that, send only the stdout to the logfile using the
logfile_read property.

Instead of redirecting qemu serial to telnet, redirect it to stdio.
It allows to run testcases in parallel without random failing caused by
two emulators trying to use the same telnet port (1234).
'qemu -serial stdio' returns some extra <CR> characters, so remove them
from the log.

Replace subprocess + telnetlib with pexpect.
Use the telnet installed on the host machine instead of telnetlib, while
the serial from qemu is not yet redirected to stdio.

We currently call infra.smart_open() to open log files each time we
need to write to them.
Opening the file once in the constructor of Builder and Emulator and
writing to it whenever needed is simpler and slightly more efficient.
Remove smart_open and instead create a new open_log_file() function
which just opens the logfile. Also let it compute the filename, in
order to simplify even further the Builder and Emulator code.

This commit adds the core of a new testing infrastructure that allows to
perform runtime testing of Buildroot generated systems. This
infrastructure uses the Python unittest logic as its foundation.
This core infrastructure commit includes the following aspects:
- A base test class, called BRTest, defined in
support/testing/infra/basetest.py. This base test class inherited
from the Python provided unittest.TestCase, and must be subclassed by
all Buildroot test cases.
Its main purpose is to provide the Python unittest setUp() and
tearDown() methods. In our case, setUp() takes care of building the
Buildroot system described in the test case, and instantiate the
Emulator object in case runtime testing is needed. The tearDown()
method simply cleans things up (stop the emulator, remove the output
directory).
- A Builder class, defined in support/testing/infra/builder.py, simply
responsible for building the Buildroot system in each test case.
- An Emulator class, defined in support/testing/infra/emulator.py,
responsible for running the generated system under Qemu, allowing
each test case to run arbitrary commands inside the emulated system.
- A run-tests script, which is the entry point to start the tests.
Even though I wrote the original version of this small infrastructure, a
huge amount of rework and improvement has been done by Maxime
Hadjinlian, and squashed into this patch. So many thanks to Maxime for
cleaning up and improving my Python code!
