improve precision of set constructs in Nitpick

produce more potential counterexamples for subset operator (cf. quantifiers)

improved Sledgehammer proofs

pass "full_type" argument to proof reconstruction

made Sledgehammer's full-typed proof reconstruction work for the first time; previously, Isar proofs and full-type mode were mutually exclusive because both options were hard-coded in the ATP names (e.g., "e_isar" and "full_vampire") -- making the options orthogonal revealed that some code was missing to handle types in the proof reconstruction code

delect installed ATPs dynamically, _not_ at image built time

Fix syntax; apparently constant apply was introduced in an earlier changeset.

Merged.

Add mixin to base morphism, required by class package; cf ab324ffd6f3d.

Remove improper use of mixin in class package.

Multiset: renamed, added and tuned lemmas; Permutation: replaced local "remove" by List.remove1

use 'subsection' instead of 'section', to maintain 1 chapter per file in generated document

more precise dependencies

updated SMT certificates

layered SMT setup, adapted SMT clients, added further tests, made Z3 proof abstraction configurable

integrated SMT into the HOL image

replaced More_conv.top_conv (which does not re-apply the given conversion to its results, only to the result's subterms) by Simplifier.full_rewrite

use proper context operations (for fresh names of type and term variables, and for hypothetical definitions), monomorphize theorems (instead of terms, necessary for hypothetical definitions made during lambda lifting)

split monolithic Z3 proof reconstruction structure into separate structures, use one set of schematic theorems for all uncertain proof rules (to extend proof reconstruction by missing cases), added several schematic theorems, improved abstraction of goals (abstract all uninterpreted sub-terms, only leave builtin symbols)

added tracing of reconstruction data

added new SMT translation files which use a simpler intermediate term representation and a simpler translation of builtin symbols, have less overhead for renaming symbols and generating the signature, add come with a simpler separation of formulas and terms

deleted SMT translation files (to be replaced by a simplified version)

move the addition of extra facts into a separate module

normalize numerals: also rewrite Numeral0 into 0

added missing rewrite rules for natural min and max

rewrite bool case expressions as if expression

simplified normalize_rule and moved it further down in the code

merged addition of rules into one function

added simplification for distinctness of small lists

moved the addition of DLO tactic into the Z3 theory (DLO is required only for Z3 proof reconstruction)

added Proofterm.unconstrain_thm_proof for Thm.unconstrainT -- loosely based on the version by krauss/schropp;

conditionally unconstrain thm proofs -- loosely based on the version by krauss/schropp;

the_classrel/the_arity: avoid Thm.transfer for proofterm version -- theory might already have become stale within the proof_body future;

avoid redundant rebinding of name/prop -- probably introduced accidentally in 80bb72a0f577;

raise Fail uniformly for proofterm errors, which appear to be rather low-level;

unconstrainT operations on proofs, according to krauss/schropp;

added Proofterm.get_name variants according to krauss/schropp; tuned signature;

conditional structure SingleAssignment;
