*
Redefine bigops to get more definitional equalities.

Various new specification patterns for
`done`
and framing.
*
Improve solve_ndisj.

There is common machinery for symbolic execution of pure reductions. This
is provided by the type classes
`PureExec`
and
`IntoVal`
.

There is a new connective
`tc_opaque`
, which can be used to make definitions
opaque for type classes, and thus opaque for most tactics of the proof
mode.

Many missing type class instances for distributing connectives have been
defined.
*
The generic
`fill`
operation of the
`ectxi_language`
construct has been
defined in terms of a left fold instead of a right fold. This gives rise to
more definitional equalities.
*
The big operators have been improved:
+
They are no longer tied to cameras, but work on any monoid
+
The version of big operations over lists was redefined so that it enjoy more
definitional equalities.

`solve_ndisj`
