Add random.randbytes() function and random.Random.randbytes()
method to generate random bytes.
Modify secrets.token_bytes() to use SystemRandom.randbytes()
rather than calling directly os.urandom().
Rename also genrand_int32() to genrand_uint32(), since it returns an
unsigned 32-bit integer, not a signed integer.
The _random module is now built with Py_BUILD_CORE_MODULE defined.

bpo-35513, unittest: TextTestRunner uses time.perf_counter() (GH-11180)

TextTestRunner of unittest.runner now uses time.perf_counter() rather

can go backwards, whereas time.perf_counter() is monotonic.
Similar change made in libregrtest, pprint and random.

Currently, the *n* and *total* variables get converted to floats each time they are multiplied by random(). This minor tweak does the conversion just once and gets a small speedup (approx 3%).
