- emphasizing the different kinds of patterns
- factorizing code of the non-naming intro-patterns
Still some questions:
- Should -> and <- apply to hypotheses or not (currently they apply to
hypotheses either when used in assert-style tactics or apply in, or
when the term to rewrite is a variable, in which case "subst" is
applied)?
- Should "subst" be used when the -> or <- rewrites an equation x=t
posed by "assert" (i.e. rewrite everywhere and clearing x and hyp)?
- Should -> and <- be applicable in non assert-style if the lemma has
quantifications?

- made "apply" tactics of type Proofview.tactic, as well as other inner
functions about elim and assert
- used same hypothesis naming policy for intros and internal_cut (towards a
reorganization of intro patterns)
- "apply ... in H as pat" now supports any kind of introduction
pattern (doc not changed)

Also taking advantage of the change to rename it into TacML. Ultimately
should allow ML tactic to return values.

NoOccurenceFound when only typeclass resolution failed. Might break
some scripts relying on backtracking on typeclass resolution failures
to find other terms to rewrite, which can be fixed using occurrences
or directly setoid_rewrite.

The lexer parses bullets only at the beginning of sentence. In
particular, the lexer recognizes sentences (this feature was
introduced for the translator and it is still used for the
beautifier). It recognized "." but not "...'. I added "..." followed
by space or eol as a terminator of sentences. I hope this is
compatible with the rest of the code dealing with end of
sentences.
Fixed also parse_to_dot which was not aware of "...".
Maybe there are similar things to do with coqide or PG?

Names and arguments were uniformized, and some functions were redesigned to

The levels added by the context are in general much fewer than the size of the
evarmap, so it is better to add them to the latter rather than doing it the
other way around.

a primitive application only if all parameters of [p] are implicit, falling
back to the internalization of the eta-expanded version otherwise. This makes
apply [p] succeed even if its record argument is not implicit, ensuring better
compatibility.

Fixes PTSF (though I have no idea what caused this bug to show up just yesterday).

In theory [Proofview.Goal.env] should be, itself, marked as requiring a normalised goals (as it includes [hyps] which does). However, it is impractical as it is very common to pass a goal environment to a function reasoning modulo evars. So I guess we are bound to mark the appropriate functions by hand.

all the tactics using the constructor keyword in one entry. This has the
side-effect to also remove the other variant of constructor from the AST.
I also needed to hack around the "tauto" tactic to make it work, by
calling directly the ML tactic through a TacExtend node. This may be
generalized to get rid of the intermingled dependencies between this
tactic and the infamous Ltac quotation mechanism.
