(This is in part a temporary solution since the ",bt" command is now used
to show a backtrace as well as any "foo...:" hidden fields.)
(cherry picked from commit c2bea19d1b)
Fix tchecking for a rest argument to a function that
is lifted by closure conversion so that one of its
arguments is a mutable local variable's location.
Also reject bytecode that would pass too many arguments
to a lifted function, since that would trigger an arity
error that might try to use a location as a value.
Merge to v5.3
(cherry picked from commit 9d6f0e96ba)
appear in saved wxme format files
also, improve the testing support for testing snip loading
(before this, the testing infrastructure could let one test
"leak" into another one in a way that could mask failures)
please include in release branch
(cherry picked from commit b342009e71)
Leave it working in splicing mode. I prefer doing that over always
splicing them, since that would make a less uniform interface, so I
rather keep all options open. There is no longer a `#:nothing' keyword,
which is the main point of this downgrade.
(See mailing list discussion on "no-argument" for the reason.)

and the change to the racket/gui load-handler
(unfortunately, there is still another problem that keeps
the test suite from passing)

When a module is loaded from bytecode and then the value of
`use-compiled-file-paths' changes, an attempt to load a submodule
would fail, because source isn't used if the main module is
already declared, and the bytecode code is not used according to
`use-compiled-file-paths'. Make the bytecode path stick when it
is used once, so that submodule loads succeed, and make it work
even with `namespace-module-attach'.
The module-attach part of this protocol requires a change to the
API of a module name resolver: the notification mode gets two
arguments, instead of one, where the second argument is an
environment.
The lambda-lifting transformation needs to iterate to a fixpoint
where each lambda's added arguments and order are known. The
check for whether something changed was formerly just the number
of added arguments, but that's not good enough, because a binding
might get lifted away while another one acquires an extra argument.
The right test is to check the count and original bindings for the
added arguments.

- Allow indexing into a VectorTop, with result `Any`.
- Don't use special typing rules for applications when the operator
has an annotation or instantiation.

Closes PR 12888.
The optional arguments for `call-as-current' for `gl-context<%>'
were not implemented, and the locking implementation didn't match
the documentation in other ways.
