Library.merge/OrdList.union: optimize the important special case where the tables coincide -- NOTE: this changes both the operational behaviour and the result for non-standard eq/ord notion;

reduced verbosity;

made SML/NJ happy

tuned interpunctation

strip_abss: always strip abstractions as far as possible, without keeping alternatives (which appear to be redundant anyway, but cause significant slowdown since discrimination nets collapse abstractions);

close/all_assm_tac: finish all subgoals from left to right (cf. Proof.goal_tac a28d83e903ce) -- NB: ALLGOALS/THEN_ALL_NEW operate from right to left;

reverted abbreviations: improved performance via Item_Net.T;

export match_rew -- useful for implementing "procs" for rewrite_term;

tuned comment;

merged

document new additions to HOL/Library

clean up proofs

adapted to general Item_Net;

turned structure NetRules into general Item_Net, which is loaded earlier;

renamed Tactic.taglist/untaglist/orderlist to tag_list/untag_list/order_list (in library.ML);

goal_tac: finish marked assumptions from left to right -- corresponds better with the strategy of etac, with significant performance gains in some situations;

eq_assumption: slightly more efficient by checking (open) result of Logic.assum_problems directly; tuned;

tuned aeconv: test plain aconv before expensive eta_contract;

substantial speedup of assumption and elim-resolution: Logic.assum_problems refrains from eager application of parameters, discriminate via Term.could_unify before invoking full unification (assumes terms in beta-normal form, as do higher term net operations anyway);

refined is_norm_hhf: reject beta-redexes (rules based on term nets or could_unify assume normal form), also potentially faster by avoiding expensive Envir.beta_eta_contract;

provide Simplifier.norm_hhf(_protect) as regular simplifier operation;

method parser: pass proper context;
