parse/ast/data_smart: Add parsing flag to getVar/setVar
When parsing we find problems if we clear prepends/appends when
setting variables during the initial parsing phases. Later, we actively
want to do this (in what would be post finalisation previously).
To handle this, pass a parsing flag to the operations to control
the correct behaviour for the context.
