Add TypeParamDetails for symbols that represent type parameters.
Create such symbols when a type-param-def-stmt is encountered.
At the end of the derived-type-def, check the parameters named
in the type-param-name-list against those encountered in each
type-param-def-stmt.

Add new kinds of symbol details: ProcBindingDetails, FinalProcDetails.
and GenericBindingDetails. The last is not yet implemented.
Write them to the .mod file.
Recognize DEFERRED and NON_OVERRIDABLE attributes. Enforce C783.
Resolve CLASS(t) similarly to resolution of TYPE(t).

Resolve names and do implicit typing in ArrayElement and LoopBounds.
Fix problem with creation of UseErrorDetails: when a conflict occurs,
record both the original USE and the new one.
Resolve the type name in TypeAttrSpec::Extends. Move CheckUseError to
DeclarationVisitor so that it can be used in ResolveDerivedType.
Report error on unresolved names. I.e. after name resolution, check each
parser::Name and verify we have a Symbol for it. This is on by default
now but it could be an option.

A `BLOCK` statement opens a new scope. It is different from other scopes
in that implicitly typed entities are defined in the enclosing non-block
scope, not immediately in the block. This means that `IMPORT` statements
can cause them to be hidden.
Check that blocks can't have `IMPLICIT` statements in them. It is simpler
for the parser not to deal with the different between a
specification-part and a block-specification-part.
Change `ImplicitRules` to have a parent that is consulted when there isn't
an answer in the current one. For an interface body that does not happen
but for all other nested scopes it does. This parent link eliminates the
need for the `implicitRules_` stack. Make `isImplicitNoneType_` and
`isImplicitNoneExternal_` optional: not set means look in parent.
Fixesflang-compiler/f18#71.
Remove `CurrNonTypeScope()` and put the logic in `Symbol::FindSymbol`.

`CurrScope()` is now a simple accessor with no logic, so rename to `currScope()`.
`PushScope()` doesn't need to return a `Scope&` and the other functions
with that name do not, so make it consistent.

Host association is done by search for symbols using `Scope::FindSymbol()`
which looks for the the name in the parent scope if the import rules
permit it.
Import statements are implemented using `importKind_` and `importNames_`
in class `Scope`. Most of the constraints are checked when the
`ImportStmt` is encountered. `CheckImports()` is called at the end of
the `SpecificationPart` to verify the names mentioned in the IMPORT
statement. That has to happen then so that we can detect if an imported
name is hidden by a declaration in the current scope.

We don't need to manage a stack of scopes: each scope has a reference to
its parent, so popping the scope stack is equivalent to setting the
new current scope to the parent of the old current scope.

Verify that checksums are correct when reading a module file.
Don't write a module file if its current contents are correct.
Don't make .mod files read-only. It doesn't do much to prevent
users from editing them, checksum verification will detect when
it happens, and having them read-only causes problems if you then
compile with another compiler (e.g. PGI).
