93602e3af7 [3.5] bpo-29537: Tolerate legacy invalid bytecode (#169) 
bpo-27286 fixed a problem where BUILD_MAP_UNPACK_WITH_CALL could
be emitted with an incorrect oparg value, causing the eval loop
to access the wrong stack entry when attempting to read the
function name.

The associated magic number change caused significant problems when
attempting to upgrade to 3.5.3 for anyone that relies on pre-cached
bytecode remaining valid across maintenance releases.

This patch restores the ability to import legacy bytecode generated
by 3.5.0, 3.5.1 or 3.5.2, and modifies the eval loop to
avoid any harmful consequences from the potentially malformed legacy
bytecode.

Original import patch by Petr Viktorin, eval loop patch by Serhiy Storchaka,
and tests and integration by Nick Coghlan.

a2edd3ae40 [3.5] bpo-27593: Get SCM build info from git instead of hg. (#446) (#454) (#455) 
* bpo-27593: Get SCM build info from git instead of hg. (#446)

sys.version and the platform module python_build(),
python_branch(), and python_revision() functions now use
git information rather than hg when building from a repo.

Based on original patches by Brett Cannon and Steve Dower.

035ba5da3e Issue #29157: Prefer getrandom() over getentropy() 
Copy and then adapt Python/random.c from default branch. Difference between 3.5
and default branches:

* Python 3.5 only uses getrandom() in non-blocking mode: flags=GRND_NONBLOCK
* If getrandom() fails with EAGAIN: py_getrandom() immediately fails and
  remembers that getrandom() doesn't work.
* Python 3.5 has no _PyOS_URandomNonblock() function: _PyOS_URandom()
  works in non-blocking mode on Python 3.5
