In pat%constr, creating new evars is now allowed only if "eintros" is
given, i.e. "intros" checks that no evars are created, and similarly
e.g. for "injection ... as ... pat%constr".
The form "eintros [...]" or "eintros ->" with the case analysis or
rewrite creating evars is now also supported.
This is not a commitment to say that it is good to have an e- modifier
to tactics. It is just to be consistent with the existing convention.
It seems to me that the "no e-" variants are good for beginners. However,
expert might prefer to use the e-variants by default. Opinions from
teachers and users would be useful.
To be possibly done: do that [= ...] work on hypotheses with side
conditions or parameters based on the idea that they apply the full
injection and not only the restriction of it to goals which are
exactly an equality, as it is today.

simpler re-printing of assert.
Also fixing the precedence for printing "by" clause.

Note that this breaks the compatibility, in a beneficial way I believe. Tactics
defined in strict mode (i.e. through Ltac foo := ...) may not do an introduction
on a local identifier anymore. They must use the "fresh" primitive instead.

This patch splits pretty printing representation from IO operations.
- `Pp` is kept in charge of the abstract pretty printing representation.
- The `Feedback` module provides interface for doing printing IO.
The patch continues work initiated for 8.5 and has the following effects:
- The following functions in `Pp`: `pp`, `ppnl`, `pperr`, `pperrnl`,
`pperr_flush`, `pp_flush`, `flush_all`, `msg`, `msgnl`, `msgerr`,
`msgerrnl`, `message` are removed. `Feedback.msg_*` functions must be
used instead.
- Feedback provides different backends to handle output, currently,
`stdout`, `emacs` and CoqIDE backends are provided.
- Clients cannot specify flush policy anymore, thus `pp_flush` et al are
gone.
- `Feedback.feedback` takes an `edit_or_state_id` instead of the old
mix.
Lightly tested: Test-suite passes, Proof General and CoqIDE seem to work.

variables" when matching over "{v : _ | _ & _}" which hides twice the
binding "fun v" since it is "sig2 (fun v => _) (fun v => _)".
Computing the bound variables statically at internalisation time
rather than every time at interpretation time. This cannot hurt even
if I don't know how to deal with the "notation" problem of a single
bound variable actually hiding two: at the current time, the notation
is printed only if the two variables are identical (see #4592), so,
with this semantics the warning should not be printed, but we lost the
information that we are coming from a notation; if #4592 were
addressed, then one of the binding should be alpha-renamed if they
differ, so collision should be solved by choosing the variable name
which is not renamed, but the matching algorithm should then be aware
of what the notation printing algorithm is doing... maybe not the most
critical thing at the current time.
