Specifically, when expanding in the body of a dependent argument, put
the original variable for the dependened on field into that code, but
changing the expansion so that the binder becomes the original field's
x, not the x in the dependent declaration list.
This means that, for example, in this program:
(->i ([x any/c]
[y (x) (begin x any/c)]
[z (x) (begin x any/c)]) any)
the first x will be the binder and the other four now count as
bound occurrences.

The intent is to support phase-crossing data such as the `exn:fail:syntax'
structure type that is instantiaed by macros and recognized by contexts
that use `eval' or `expand'. Phaseless modules are highly constrained,
however, to avoid new cross-phase channels, and a module is inferred to
be phaseless when it fits syntactic constraints.
I've adjusted `racket/kernel' and improved its documentation a little
so that it can be used to implement a phaseless module (which can
import only from other phaseless modules).
This change also adds a `flags' field to the `mod' structure type
from `compiler/zo-structs'.
* The all-versions page has a docs column with html/pdf links, and also
two links in the nightly builds footer.
* Specific version download pages have a link to the docs for that
version. (Only html, to save space.)
* Move sha1 test to the same place, to be run like the others.
* Unify tests for untar and unzip.
* Also improve them: test results instead of failing with errors. Also,
generate random text to archive, and use 0 for group+other permission
bits (to avoid world writable results on an error).
Also, minor code cleanup (don't create a function and pass it
around when has only one thing in its closure and you can
just pass that around, especially when passing the function around
makes the code harder to read and the created function has to
have a "dot" arglist and use "apply" in its body)
better wrt to its first result
That is, instead of just returning the string "#lang" it now
returns the actual text that was there (it was supposed to be
doing that all along and my recent commit fixed it, but I
missed the test cases)
