25b0c23db7 expander: adjust bindings in module->namespace 
Make the module path index for bindings in a `module->namespace` be a
"self" MPI (with #f for path and base), instead of the MPI associated
with bindings as view from the outside of the module instance. That
makes interactive evalaution in the namespace more closely approximate
expansion within the original module.

Example use: ASL detects a "self" MPI to determine when it should
allow assignment to module-defined variables in the REPL.

19df146ccf expand and expand-to-top-form unset observer parameter 
This change means that if a macro transformer calls expand (not
local-expand, but top-level expand), the macro debugger won't
receive the inner expand's events. Previously, the macro debugger
tried to parse and then discard the inner expand, but that was
brittle and complicated the grammar.

4e1e91a34e peek-{char,byte}-or-special: add 'special option

`peek-{char,byte}-or-special`, and update the reader to use it.

59ef254318 switch to a new, Racket-implemented expander & module system 
This commit merges changes that were developed in the "racket7" repo.
See that repo (which is no longer modified) for a more fine-grained
change history.

The commit includes experimental support for running Racket on Chez
Scheme, but that "CS" variant is not built by default.

define-simple-macro now works with an ~or macro. (#1949) 
The previous definition of define-simple-macro would fail (with
a very poor error message) if the user made a simple macro like:

(define-simple-macro (~or a b)
  (let ([tmp a])
    (if tmp tmp b)))

While the define-simple-macro form does allow syntax-parse patterns,
this should not be enabled for the initial head pattern, as described
in the define-simple-macro documentation.

9e3bdaa328 call-in-nested-thread: add prompt 
Before 544b7a3d53, an incorrect barrier check prevented applying
a continuation captured in other threads from being applied in a
thread created with `call-in-nested-thread`. There's no good
reason to prohibit such an application, and now that the bogus
check is gone, an explicit prompt is needed in the implementation
to make it behave correctly.

fb80d18428 syntax/parse: Arrange for built-in macro’s names to be preserved 
The dance that syntax/parse performs to lazily load its implementation
rewrites uses of syntax/parse macros in such a way that their original
names were discarded, which shows up in error messages. By simply
invoking the underlying transformer directly in the proxy macro instead
of expanding to a rewritten use, users’ names can be preserved.

When a composable continuation has continuation marks that should

It only worked in the case that the merge cadidates are the only
marks, because the merging check used the wrong end of the captured
sequence of marks.

512910c83f expander: fix 'module-begin expansion with definition contexts 
Using `(local-expand <expr> 'module-begin <stops> def-ctx)` didn't
work right, because definitions added to `def-ctx` were not visible.
(While adding definitions before `module-begin` expansion is an unusual
thing to do, there's no reason that it has to fail.)

dfa5d48092 unbreak JIT and check limits 
Repairs a problem with ce9894c8bf, where a large "inlined" vector
allocation is not actually inlined, but other parts of the JIT
assume that it will behave as inlined --- which implies that the
runstack will be left unchanged after the call.

Closes #1868

1e38918aa9 Improve how splicing-syntax-parameterize interacts with module* forms 
Commit 00d438cfbe made an attempt at this,
but this commit does it in a much more careful way, based on manually
emulating how the macroexpander expands module* forms in order to allow
splicing-syntax-parameterize to apply even within #%module-begin forms
introduced by the expander.
