Prepares Flow.qll for co-existence with the new CFG facade by switching
'import python' to 'import python as Py' and qualifying every AST-class
reference inside Flow.qll's body. Flow.qll's own CFG types
(ControlFlowNode, BasicBlock, CallNode, NameNode, etc.) keep their
unqualified names.
This change is a no-op semantically:
* all 24 evaluation-order tests still pass,
* the bindings + store-load + new-CFG-SSA library tests still pass,
* compilation produces zero errors.
The change enables a follow-up commit to swap python.qll's
'import semmle.python.Flow' for 'import semmle.python.controlflow.internal.Cfg'
without triggering name-clash errors inside Flow.qll itself. Legacy
modules that still want the legacy CFG (essa/, GuardedControlFlow,
LegacyPointsTo, objects/, pointsto/, types/, dataflow/old/) will need a
similar treatment in subsequent commits.
The qualification was applied mechanically via a script that prefixed
every reference to a known AST class. The list includes the standard
AST node types from semmle.python.{Files, Variables, Stmts, Exprs,
Class, Function, Patterns, Comprehensions} plus 'Location' / 'File' /
'Folder' / 'Container' / 'ConditionBlock' / 'Delete' / 'Load'.
