src/c-types-parse.lisp: Plain types don't have `declspec' slots.
Type names count as declaration specifiers, so `scan-declspec' has to
cope with them. Fortunately, bare types don't come with tags, so this
is easy to work around.

src/module-impl.lisp: Don't emit `#line' to non-position-aware streams.
Because we can't switch back afterwards, the compiler will blame the
wrong thing. Also, if the output stream isn't position-aware, it's
probably because we're in the midst of pretty-printing something, and
forcing `#line' directives will produce hideous results.
This is all rather unfortunate. It's clearly a bug that we can't
produce pretty output and have useful error location information, but I
think this is the best I can manage right now.

src/: Rename the various `:lisp-class' properties.
Instead, there's now a separate property for each kind of metaobject.
The reason is that some declarations can produce two metaobjects, e.g.,
a message declaration might also include a direct method, and we can't
possibly use the same metaobject class for both. To resolve this, we
use different properties to name the different metaobject classes.
* For classes, we use `:lisp-metaclass' (to distinguish from a runtime
metaclass).
* For messages, `:message-class'.
* For methods, `:method-class'.
* For slots, `:slot-class'.
* For slot initializers, `:initializer-class'.

We'll treat them as equivalent to empty lists. Otherwise it's just too

Earlier there was a bug where effective methods and method entries were
emitted twice, because there were two paths to them: one directly from
the class, and one via method entry points. To resolve this, I removed
the path directly from the class.
This turns out to have been the wrong choice, because method entries are
found once for each chain, so there are still duplicates in classes with
more than one chain carrying methods. So don't iterate from method
entries to effective methods, and reinstate the direct path from the
top-level class.
