d41160f8a5 Modify environment. Now, when a builtin value is declared, if it has a unicode alternative representation, then we add it as a definition. Now, everything that occurs in the environment has been 'declared'.

e955c054ca Modify type checker. Now, it only accepts builtin values that have been declared in the environment. The idea is to be able to track which classes of builtin values have been used in a given environment. We want to be able to quantify the size of the trusted code base for a particular development.

57c0c69872 Fix bug reported by Valgrind. Reason: m_metavars is a vector of metavar_info; each metavar_info has a context; when we invoke mk_metavar the vector can grow in size, and the context is moved to a new location. The previous location is invalidated. To avoid the problem we have to save ctx in a local variable.

9d9f9797e4 Improve elaborator interface. Now, the metavariables are created inside the elaborator. The elaborator-user only needs to create placeholders. Motivaton: the placeholders are meaningful independently of the elaborator. On the other hand, the metavariables depend on the elaborator state.
