901ffdcbac fix inexact-number parsing problem 
Bug introduced in c40229f756.

f5dbd99e43 fix precision in exact->inexact on bignums 
The strategy of converting a bignum to a flonum by converting on word
boundaries can lose one bit of precision. (If the use of a word
boundary causes a single bit to get rounded away, but the first bit of
the next word is non-zero, then the rounding might have been down when
it should have been up.)

Avoid the problem by aligning relative to the high bit, instead.

c40229f756 fix reading of extflonums, including with large exponents 
Fix even basic readind when extflonums are not supported, but
also fix reading extflonums with large exponents (related to
the other recent changes to number parsing).

8e46e46d40 add more support for continuation marks in procedure impersonators 
Allow a more dynamic (than `impersonator-prop:application-mark`)
determination of continuation marks and associated values to wrap the
call of an impersonated procedure.

0e16ce4bea add internal-definition-context-{binding-identifier,track} 
When an internal-definition context is used with `local-expand`, the
any binding added to the context affect expansion, but the binding do
not appear in the expansion. As a result, Check Syntax was unable to
draw an arrow from the `s` use to its binding in

 (class object%
   (define-struct s ())
   s)

The general solution is to add the internal-definition context's
bindings to the expansion as a 'disappeared-bindings property. The new
`internal-definitionc-context-track` function does that using a new
`internal-definition-context-binding-identifier` primitive.

e3d78e44cc avoid excessive path retention in raco dist output 
This change builds on 5c909cca0d, but it better handles files that
are installed in "lib" or "share" instead of residing in a

a053c78c30 fix re-export of shadowing binding 
Mishandling of the `require`-binding table could cause
`racket/private/pre-base` to export `andmap` as syntax, for example,
instead of as a variable. The syntax-versus-variable distinction
doesn't usually matter, but it affects the order of exports in
bytecode form.
