globally use session-qualified imports; add Lib session Session-qualified imports will be required for Isabelle2018 and help clarify the structure of sessions in the build tree. This commit mainly adds a new set of sessions for lib/, including a Lib session that includes most theories in lib/ and a few separate sessions for parts that have dependencies beyond CParser or are separate AFP sessions. The group "lib" collects all lib/ sessions. As a consequence, other theories should use lib/ theories by session name, not by path, which in turns means spec and proof sessions should also refer to each other by session name, not path, to avoid duplicate theory errors in theory merges later. 2018-06-13 07:55:36 +00:00			`imports Main`
