New submission from STINNER Victor <vstin...@redhat.com>:

Eric Snow moved global variables into a _PyRuntimeState structure which is made 
of sub-structures. There is a single instance of _PyRuntimeState: the 
_PyRuntime global variable.

I would like to add "_PyRuntimeState *" parameters to functions to avoid 
relying directly on _PyRuntime global variable. The long term goal is to have 
"stateless" code: don't rely on global variables, only on input parameters. In 
practice, we will continue to use thread local storage (TLS) to get the 
"current context" like the current interpreter and the current Python thread 
state.
