Split the opam packages into why3 and why3-ide.

For the sake of opam pinning, the opam directories have been moved to the
root directory. They can be moved back into opam/ once opam 2.0 has been
released.

opam/why3-base/descr

-Why3 environment for deductive program verification (base)
-
-This package is for advanced users only, normal users should use the
-full why3 package.

why3-ide.opam/descr

+Why3 environment for deductive program verification.
+
+Why3 provides a rich language for specification and programming, called
+WhyML, and relies on external theorem provers, both automated and
+interactive, to discharge verification conditions. Why3 comes with a
+standard library of logical theories (integer and real arithmetic,
+Boolean operations, sets and maps, etc.) and basic programming data
+structures (arrays, queues, hash tables, etc.). A user can write WhyML
+programs directly and get correct-by-construction OCaml programs
+through an automated extraction mechanism. WhyML is also used as an
+intermediate language for the verification of C, Java, or Ada
+programs.
+
+Why3 is a complete reimplementation of the former Why platform. Among
+the new features are: numerous extensions to the input language, a new
+architecture for calling external provers, and a well-designed API,
+allowing to use Why3 as a software library. An important emphasis is
+put on modularity and genericity, giving the end user a possibility to
+easily reuse Why3 formalizations or to add support for a new external
+prover if wanted.
+
+This package provides an IDE for Why3.
