thm_deps/unused_thms: Context.get_theory based on proper theory ancestry, not accidental theory loader state;

explicit dependency on theory HOL;

ML antiquotations @{theory} and @{theory_ref} refer to the theory ancestry, not any accidental theory loader state; recovered @{theory_ref NAME} (cf. 1f09a22a1027);

added Context.get_theory -- avoid referring to accidental theory loader state (cf. Thy_Info.get_theory);

thy_deps: more direct comparison of sessions, which is presumably what "unfold" is meant to indicate here -- also avoid referring to accidental theory loader state;

clarified/exported Future.worker_subgroup, which is already the default for Future.fork;

qualified Thy_Info.get_theory;

discontinued pervasive val theory = Thy_Info.get_theory -- prefer antiquotations in most situations;

further Mac OS X deviations;

warning in proper transaction context;

SML/NJ: refrain from modifying toplevel pp for type string -- unclear if it could work here;

avoid duplicate printing of 'theory' state (cf. 173974e07dea);

toplevel pp for Proof.state and Toplevel.state;

execute document version at high priority;

Topelevel.run_command: interactive mode for initial 'theory' ensures that Thy_Info.begin_theory loads parent theories;

edit_document: join parent execution in synchronous/uninterruptible mode, to prevent spurious interrupts when cascaded executions run into each other;

back to more strict dependencies, even for canceled groups (reverting parts of 02936e77a07c); cancel passive tasks more actively via Exn.Interrupt, by treating them like ragular jobs here; attempts to re-assign canceled futures/promises raise Exn.Interrupt; tuned;

export Graph.get_entry for convenience;

eliminated old-style sys_error/SYS_ERROR in favour of exception Fail -- after careful checking that there is no overlap with existing handling of that; tuned some error messages;

tuned;

observe follow_caret (again);

Session: predefined real time parameters; Document_View: delayed caret handling, for improved reactivity; selected_command: proper_command_at ignores ignored commands;

bind and then latex symbols

minor update of dependencies;
