When building U-Boot we should not blindly use make -j8 but consider the
actual core count given by os.cpu_count().

It is a pain to have to set the CROSS_COMPILE environment variable when
using test.py's --build option. It is possible to get this using the -A
option from buildman. But it seems better to just use buildman to do the
build when it is available.

However using buildman adds a new dependency to the test system which we
want to avoid. So leave the default as is and add a flag to make it use
buildman.

Note that most of these changes relate to test.py and the parts of the
travis/gitlab/azure scripts which relate to running test and building a
suitable U-Boot to run the tests on.

Consider the following test sample:

@pytest.mark.buildconfigspec('fit')
@pytest.mark.notbuildconfigspec('generate_acpi_table')
def test_sample(u_boot_console):

Whatever the argument of the 'notbuildconfigspec' is,
the test ends up being skipped with the message:

('/uboot/test/py/conftest.py', 463,
 'Skipped: .config feature "fit" enabled')

Buildman doesn't store this file in the same directory as a normal build.
Update the conftest code to handle both cases.

- Modern pytest is more visible in telling us about parameters that we
  had not described, so describe a few more.
- ConfigParser.readfp(...) is now configparser.read_file(...)
- As part of the "strings vs bytes" conversions in Python 3, we use the
  default encoding/decoding of utf-8 but in some places tell Python to
  replace problematic conversions rather than throw a fatal error.
- Fix a typo noticed while doing the above ("tot he" -> "to the").
- As suggested by Stephen, re-alphabetize the import list
- Per Heinrich, replace how we write contents in test_fit.py

Use the 2to3 tool to perform numerous automatic conversions from Python
2 syntax to Python 3.  Also fix whitespace problems that Python 3
catches that Python 2 did not.

We already can let a Python test depend on a build option being set via
@pytest.mark.buildconfigspec(). It may be necessary to let a test depend on
a build option *not* being set. So let's introduce

    @pytest.mark.notbuildconfigspec

for this purpose.
