[PATCH v3 14/34] qapi/introspect: Rename *qlit* to reduce confusion


From: Markus Armbruster
Subject: [PATCH v3 14/34] qapi/introspect: Rename *qlit* to reduce confusion
Date: Sun, 15 Mar 2020 15:46:33 +0100

We generate the value of qmp_schema_qlit from an expression tree.  The
function doing that is named to_qlit(), and its inputs are accumulated
in QAPISchemaGenIntrospectVisitor._qlits.  We call both its input and
its output "qlit".  This is confusing.

Use "tree" for input, and "qlit" only for output: rename to_qlit() to
_tree_to_qlit(), ._qlits to ._trees, ._gen_qlit() to ._gen_tree().
