getter/setters instead of overriding a method
this has the benefit that the delegate does not have to be
rebuilt when switching tabs in drracket; we just leave the
old delegate on the old definitions text, and the swap it
back into the editor-canvas when we swap the text% object
itself back in.
Track fixnum results in the same way as flonum results to enable
unboxing, if that turns out to be useful. The intent of the change,
though, is to support other types in the future, such as "extnums".
The output `raco decompile' no longer includes `#%in', `#%flonum',
etc., annotations, which are mostly obvious and difficult to
keep in sync with the implementation. A local-binding name now
reflects a known type, however.
The change includes a bug repair for he bytecode compiler that
is independent of the generalization (i.e., the new test case
triggered the old problem using flonums).
The new function allows declaration of a module dependency, as
opposed to a mere file dependency. Misuse of this function opens
the door to cyclic compilation dependencies, so we have to check
for that in `compiler/cm'.
Also, log a warning when it is used in a position where it
doesn't work rght with the executable creator. I didn't make
this case an error, because `define-runtime-path' can still
work in that case as long as no standalone executable needs
to be created.
I started from tabs that are not on the beginning of lines, and in
several places I did further cleanings.
If you're worried about knowing who wrote some code, for example, if you
get to this commit in "git blame", then note that you can use the "-w"
flag in many git commands to ignore whitespaces. For example, to see
per-line authors, use "git blame -w <file>". Another example: to see
the (*much* smaller) non-whitespace changes in this (or any other)
commit, use "git log -p -w -1 <sha1>".
Add "Version" in front of a version name via `.version:before' or
`.versionNoNav:before' and `\SVersionBefore', so that they can
be configured through overriding CSS or Latex macro declarations.
Also, improve the documentation for how the `#:version' argument
of `title' is propagated to a `part' style property.

Shape information allows the linker to check the importing
module's compile-time expectation against the run-time
value of its imports. The JIT, in turn, can rely on that
checking to better inline structure-type predicates, etc.,
and to more directy call JIT-generated code across
module boundaries.
In addition to checking the "shape" of an import, the import's
JITted vs. non-JITted state must be consistent. To prevent shifts
in JIT state, the `eval-jit-enabled' parameter is now restricted
in its effect to top-level bindings.
Updated example for for/digits to avoid confusion: it's not clear
otherwise that the intentional syntax error wasn't just a casual
mistake.
Added an example for sequence-add-between.
Turn use of a finalized ffi callout into a reported error,
instead of a crash. Clarify the existence of the finalizer
in the docs. Fix error logging of the finalizer thread.
Merge to v5.3.1
Bytecode changes in two small ways to help the validator:
* a cross-module variable reference preserves the compiler's
annotation on whether the reference is constant, fixed, or other
* lifted procedures now appear in the module body just before the
definitions that use them, instead of at the beginning of the
module body
The new argument gets to chaperone/impersonate a guard at
the prompt, and it is applied when the continuation is applied ---
based on a wrapper on th prompt tag of the continuation (as opposed to
the prompt tag of the prompt).
