Issue #19936: Added executable bits or shebang lines to Python scripts which

requires them.  Disable executable bits and shebang lines in test and
benchmark files in order to prevent using a random system python, and in
source files of modules which don't provide command line interface.  Fixed
shebang lines in the unittestgui and checkpip scripts.

+- Issue #19936: Added executable bits or shebang lines to Python scripts which
+  requires them.  Disable executable bits and shebang lines in test and
+  benchmark files in order to prevent using a random system python, and in
+  source files of modules which don't provide command line interface.  Fixed
+  shebang lines in the unittestgui and checkpip scripts.

 - Issue #20268: Argument Clinic now supports cloning the parameters and
   return converter of existing functions.
