Cleaning the status of Local Definition and similar.
Formerly, knowing if a declaration was to be discharged, to be global
but invisible at import, or to be global but visible at import was
obtained by combining the parser-level information (i.e. use of
Variable/Hypothesis/Let vs use of Axiom/Parameter/Definition/..., use
of Local vs Global) with the result of testing whether there were open
sections.
We change the meaning of the Discharge flag: it does not tell anymore
that it was syntactically a Variable/Hypothesis/Let, but tells the
expected semantics of the declaration (issuing a warning in the
parser-to-interpreter step if the semantics is not the one suggested
by the syntax). In particular, the interpretation/command engine
becomes independent of the parser.
The new "semantic" type is:
type import_status = ImportDefaultBehavior | ImportNeedQualified
type locality = Discharge | Global of import_status
In the process, we found a couple of inconsistencies in the treatment
of the locality status. See bug #8722 and test file LocalDefinition.v.
