090543736f Issue #19512: add some common identifiers to only create common strings once, 
instead of creating temporary Unicode string objects

Add also more identifiers in pythonrun.c to avoid temporary Unicode string
objets for the interactive interpreter.

d02fbb8f71 Issue #19512: sys_displayhook() now uses an identifier for "builtins" 
dictionary key and only decodes "\n" string once to write a newline.

So "builtins" and "\n" are only decoded once from UTF-8, at the first call.

41bb43a71e Issue #18408: Add a new PyFrame_FastToLocalsWithError() function to handle

ad73a9cf97 Issue #16400: Add command line option for isolated mode. 
-I

    Run Python in isolated mode. This also implies -E and -s. In isolated mode
    sys.path contains neither the script’s directory nor the user’s
    site-packages directory. All PYTHON* environment variables are ignored,
    too. Further restrictions may be imposed to prevent the user from
    injecting malicious code.

1c8f059019 Issue #18520: Add a new PyStructSequence_InitType2() function, same than 
PyStructSequence_InitType() except that it has a return value (0 on success,
-1 on error).

 * PyStructSequence_InitType2() now raises MemoryError on memory allocation failure
 * Fix also some calls to PyDict_SetItemString(): handle error

f9d0b1256f Issue #13390: New function :func:sys.getallocatedblocks() returns the number of memory blocks currently allocated. 
Also, the ``-R`` option to regrtest uses this function to guard against memory allocation leaks.

3adc7b75a5 Issue #15242: Have PyImport_GetMagicTag() return a const char * 
defined in sysmodule.c instead of straight out of a Unicode object.

Thanks to Amaury Forgeot d'Arc for noticing the bug and Eric Snow for
writing the patch.

09a7c72cad Merge from 3.1: Issue #13703: add a way to randomize the hash values of basic types (str, bytes, datetime) 
in order to make algorithmic complexity attacks on (e.g.) web apps much more complicated.

The environment variable PYTHONHASHSEED and the new command line flag -R control this
behavior.
