Syncing with lots of upstream bug fixes and security fixes.

Bug fixes :

CVE-2019-9674: Improved the documentation to reflect the dangers of zip-bombs (bsc#1162825).

CVE-2019-18348: Fixed a CRLF injection via the host part of the url passed to urlopen(). Now an InvalidURL exception is raised (bsc#1155094).

Fixed mismatches between libpython and python-base versions (bsc#1162224).

Fixed segfault in libpython2.7.so.1 (bsc#1073748).

Unified packages among openSUSE:Factory and SLE versions (bsc#1159035).

Added idle.desktop and idle.appdata.xml to provide IDLE in menus (bsc#1153830).

Excluded tsl_check files from python-base to prevent file conflict with python-strict-tls-checks package (bsc#945401).

Changed the name of idle3 icons to idle3.png to avoid collision with Python 2 version (bsc#1165894).

Additionally a new 'shared-python-startup' package is provided containing startup files.

python-rpm-macros was updated to fix :

Do not write .pyc files for tests (bsc#1171561)
