Issue #29157 : getrandom() is now preferred over getentropy()
...
The glibc now implements getentropy() on Linux using the getrandom() syscall.
But getentropy() doesn't support non-blocking mode.
Since getrandom() is tried first, it's not more needed to explicitly exclude
getentropy() on Solaris. Replace:
if defined(HAVE_GETENTROPY) && !defined(sun)
with
if defined(HAVE_GETENTROPY)

Issue #29157 : dev_urandom() now calls py_getentropy()
...
Prepare the fallback to support getentropy() failure and falls back on reading
from /dev/urandom.

os.urandom() now blocks on Linux
...
Issue #27776 : The os.urandom() function does now block on Linux 3.17 and newer
until the system urandom entropy pool is initialized to increase the security.
This change is part of the PEP 524.

Issue #27776 : _PyRandom_Init() doesn't call PyErr_CheckSignals() anymore
...
Modify py_getrandom() to not call PyErr_CheckSignals() if raise is zero.
_PyRandom_Init() is called very early in the Python initialization, so it's
safer to not call PyErr_CheckSignals().
