* "fail*" and "assert*" aliases of TestCase methods.
* Broken from start TestCase method assertDictContainsSubset().
* Ignored TestLoader.loadTestsFromModule() parameter use_load_tests.
* Old alias _TextTestResult of TextTestResult.
Previously, test classes ISOTPTest, J1939Test, BasicUDPLITETest and
UDPLITETimeoutTest were not included in the list of tests and
were not run by regrtest.
The main advantage is that the files will no longer show up in diffs and PRs. That means, for a PR, the number of files / lines changed will more clearly reflect the actual change. (This is essentially an un-revert of gh-28375.)

tearDown() is not called if setUp() raises an exception
(including SkipTest). addCleanup() should be used for guaranteed
execution of the cleanup code.

Here's one more small cleanup that should have been in PR gh-28319. We eliminate stdout side-effects from importing the frozen __hello__ module, and update tests accordingly. We also move the module's source file into Lib/ from Toos/freeze/flag.py.

Make test_compileall quiet: test_year_2038_mtime_compilation() and
test_larger_than_32_bit_times() of test_compileall no longer log
"Compiling ..." messages to stdout.
This will enable us to drop the frozen module header files from the repository.
It does currently cause many source files to be built twice, which just takes more time. For whoever comes to fix this in the future, the files shared between freeze_module and pythoncore should be put into a static library that is consumed by both.
Doing this provides significant performance gains for runtime startup (~15% with all the imported modules frozen). We don't yet freeze all the imported modules because there are a few hiccups in the build systems we need to sort out first. (See bpo-45186 and bpo-45188.)
Note that in PR GH-28320 we added a command-line flag (-X frozen_modules=[on|off]) that allows users to opt out of (or into) using frozen modules. The default is still "off" but we will change it to "on" as soon as we can do it in a way that does not cause contributors pain.

Refactor pytime.c:
* Add pytime_from_nanoseconds() and pytime_as_nanoseconds(),
and use explicitly these functions
* Add two empty lines between functions
* PEP 7: add braces { ... }
* C99: declare variables where they are set
* Rename private functions to lowercase
* Rename error_time_t_overflow() to pytime_time_t_overflow()
* Rename win_perf_counter_frequency() to py_win_perf_counter_frequency()
* py_get_monotonic_clock(): add an assertion to detect overflow when
mach_absolute_time() unsigned uint64_t is casted to _PyTime_t
(signed int64_t).
_testcapi: use _PyTime_FromNanoseconds().
The line that should not have been needed on macOS tk 8.6.8 but was,
should not be a problem on Ubuntu, but is. It is not needed on macOS
tk 8.6.11, installed with 3.10. Disable it but leave it for
now in case some system needs it.
Currently we freeze several modules into the runtime. For each of these modules it is essential to bootstrapping the runtime that they be frozen. Any other stdlib module that we later freeze into the runtime is not essential. We can just as well import from the .py file. This PR lets users explicitly choose which should be used, with the new "-X frozen_modules=[on|off]" CLI flag. The default is "off" for now.

There are a few things I missed in gh-27980. This is a follow-up that will make subsequent PRs cleaner. It includes fixes to tests and tools that reference the frozen modules.

In the configparser module, these have been deprecated since Python 3.2:
* the SafeConfigParser class,
* the filename property of the ParsingError class,
* the readfp method of the ConfigParser class,
In Unix operating systems, time.sleep() now uses the clock_nanosleep() function,
if available, which allows to sleep for an interval specified with nanosecond precision.
