9b04aef0f8 fix a problem with `syntax-local-lift-require' at top level 
The problem was exposed by improved error checking
in the expander to detect references to exports of a module that
is not yet visited, and as triggered by the documentation for
`2htdp/planetcute'.

23d0627acc scribble: improve HTML handling of 'unnumbered and 'toc-hidden 
A part with style property 'toc-hidden no longer
hides child sections, which makes it consistent with Latex/PDF
rendering.

A part with style 'grouper and 'unnumbered does not make its
child parts render as more nested, which is consistent with
'gruper without 'unnumbered. An unnumbered grouper is represented
as "" in a section-number list (while #f is still used for
unnumbered non-grouper layers).

840fc9c657 full unboxing for extflonums, plus `ffi/unsafe' support 
Includes a repair for floating-point `min' and `max' that affects all
x86 builds that use SSE arithmetic, leaving the (otherwise unused)
floating-point stack in a bad state, which might have affected
x87-using C/foreign libraries running alongside Racket.

ca8ad3b88b try to be slightly smarter about invalidating the green region 
in the line numbers when it moves around

specifically, if the before and after green line are right
next to each other, then put it into a single edit sequence
(which unions the invalidated regions); if not, then we
may be jumping far away, so invalidate the two regions
and redraw them separately

294bed209e macro expander fix 
Repair 73e07f576b added an item to a list without incrementing a
counter for the list length, which cause a different element of
the list to be dropped, which could mess up binding resolution in
arbitrarily bad ways.

(Ths bug falls into the "how did this not get exposed earlier?"  bin,
although part of the answer is that it requires a combination of
module re-expansion and simplification of syntax objects in the
residual program.)

405e51bb05 adjust contour to track edit sequences better 
Specifically when there is no delegate and an edit
sequence is started, track that differently in case
a delegate is set before the edit sequence ends
(in which case we don't want to end the edit
sequence in the delegate since we didn't start it
there)

Instead of assumning that the snip's text will match a font's height
metrics, check and remember the actual metrics if its doesn't match,

a3cde5fb42 adjust check syntax so it highlights all identifiers with the same 
binding site (with a green/yellow bubble) when the mouse moves over
any one of them

This change comes about because of the recent fixes to the
interactivity wrt to the rename menu. Basically, in order to fix the
bug (but still preserve the interactivity optimization), check syntax
changed from sending the information "here is a place to offer a
rename for these identifiers" to "here is a set of identifiers that
are all free-identifier=?" (the difference being that the latter does
not imply you got them all (which enables the optimization) and that
the information is slightly less rename-menu specific (which enables
the change in this commit))

17b8092641 extflonums 
An extflonum is like a flonum, but with 80-bit precision and
not a number in the sense of `number?': only operations such as
`extfl+' work on extflonums, and only on platforms where extflonums
can be implemented by hardware without interefering with flonums
(i.e., on platforms where SSE instructions are used for
double-precision floats).

[Patch provided by Michael Filonenko and revised by Matthew.]

The compiler tracks information about bindings that are known to
hold extflonums, but the JIT does not yet exploit this information
to unbox them (except as intermediate results).

aed3b39546 Added flexp2', fllog2', `fllogb'; refactored and documented flonum testing 
Note: With this refactoring, `math/utils' no longer depends on `rackunit'.

* (flexp2 x) computes (flexpt 2.0 x) but in about 1/3 the time for integer
  `x' using a lookup table. Written for exact argument reduction in `fllog2'
  after discovering that (flexpt 2.0 x) was the main performance bottleneck.

* (fllog2 x) computes (/ (fllog x) (fllog 2.0)) with near perfect accuracy.
  Invented an algorithm to compute it with at least 8 extra bits before
  final rounding; quite pleased with the result. Needed `fllog2' to ensure
  (fllogb 2.0 x) would be exact when `x' is a power of two.

* (fllogb b x) computes (/ (fllog x) (fllog b)) with better accuracy, and
  also handles limit values in a way that's consistent with the mathematical
  limits. When those are ambiguous, it's consistent with `flexpt', which
  follows IEEE 754 and C99. Otherwise returns +nan.0. See docs for details.

* `bflogb' is currently just for testing `fllogb'.

* Refactored FPU testing and documented it. So far, the only documented way
  to do it is by calling `test-floating-point', which runs a comprehensive
  deterministic+randomized suite of tests and returns a list representing
  failed tests. I'll document individual tests after I document flonum
  expansions and result/error functions like `fl+/error'.

* Added `fllog2' and `fllogb' to the flonum tests.
