reinserted legacy ML function

Set.UNIV and Set.empty are mere abbreviations for top and bot

explicit is better than implicit

Meson.first_order_resolve: avoid handle _; proper context for various Meson and Metis rules and tactics unified meson_tac/meson_claset_tac;

removed old global get_claset/map_claset; added local get_claset/put_claset;

eliminated METAHYPS;

Future.shutdown before loading sequentially -- workaround scheduler deadlock;

ResAxioms.neg_conjecture_clauses: proper context; let exceptions get through unhindered -- Poly/ML exception_trace will do the tracing;

neg_conjecture_clauses, neg_clausify_tac: proper context, eliminated METAHYPS; external_prover: neg_conjecture_clauses should handle TVars within goals; misc tuning;

Hilbert_Classical: sequential loading due to @{prf}, which joins within a critical section (via options);

eliminated separate Future.enabled -- let Future.join fail explicitly in critical section, instead of entering sequential mode silently;

non-critical use_thy;

future result: Synchronized.var;

added unsynchronized Synchronized.peek;

group status: Synchronized.var;

tuned;

Task_Queue.dequeue: explicit thread;

more precise treatment of scheduler_event: continous pulse (50ms) instead of flooding, which was burning many CPU cycles in spare threads;

interruptible_task: unified treatment of Multithreading.with_attributes (cf. 9f6461b1c9cc);

misc tuning;

tuned

moved obsolete same_fst to Recdef.thy
