9ba663aa77 preserve submoduleness in module path index for expanded submodules
The preserved path is exposed by a new `module-path-index-submodule'
function, and `module-path-index-join' now accepts an optional
submodule path.

Also, fixed a problem with `collapse-module-path-index' when
a module path indx is built on a resolved module path that
is a submodule path.

In addition to the main repair, `collapse-module-path[-index]' is
correctly documented to allow '(quote <sym>) rel-to paths.

Finally, `collapse-module-path-index' changed to use a symbolic
resolved module path that appears as the base of a module path
index, rather than falling back to the given rel-to path. It's
possble that the old beavior was intentional, but it wasn't tested,
and it seems more likely to have been a bug.

ba8684cb63 provide provide, so it's possible to use provide and require in
student languages.  This will be a problem if somebody writes a
function in BSL or BSLLA, provides it, requires it in a non-student
language, and uses it as an argument to a higher-order function
that isn't declared as a "higher order primitive".  That is,
not very often.  Even if so, just re-open the BSL or BSLLA source
file, switch languages to ISL, save it, and the problem goes away.

5e03c7cf99 Added struct/dc and cleaned up a bunch of stuff in the contract
library (mostly in opt/c)

Specifically:

- add inlining declaration for ->i helper function

- modernized the opt/c contracts and improved them so that mutually
  recursive define-opt/c functions recognize each other instead of
  bailing out to the slow path.

- added =/c as an optimized contract

- improve the error message for the between and comparison opt
  contracts

- adjust the blame struct so the name is created lazily, since opt/c
  contracts just stick a copy o the contract into the thunk that
  creates the name and we don't want to run those effects twice if we
  can help it.

aa8b280f1c adjust the splay tree implementation so that it creates fewer cons
cells when searching in the tree

Two tricks: represent lists of nodes as improper lists so singleton
lists don't allocate a cons and pass around two accumulators that
correspond to the hd & tl of a path, instead of cons'ing that up
into a list and them immediately taking it apart again

measurement: when starting up drracket with
collects/drracket/private/unit.rkt and then waiting for the colorer to
finish, and then inserting an open quote right before the first open
quote in the file (and waiting again for the colorer to finish)
creates 249000 cons cells before this change and 116000 after this
change

After a little more work, I'm pretty much convinced that this was
the wrong approach and that the splaying implementation should just
change to not allocate the paths into lists at all, thus removing
the other 116k cons cells. (I plan to get to this another day;
it should not be difficult now that I roughly understand how these
things work.)

I also looked into top-down splaying and found these notes to
be illuminating:

  http://digital.cs.usu.edu/~allan/DS/Notes/Ch22.pdf

They essentially convinced me that we cannot use top-down splaying
here, since the "reassembling" stage requires moving some arbitrary,
unexplored subtree from a right-child to a left-child, and thus the
left-subtree-length cannot be updated properly.

86572cc8c3 adjust the contract on string->url so that it actually catches all of
the errors that would be signalled by the body. also, remove
url-regexp from the exports (it was only recently added)

I believe this eliminates two of Eli's concerns:

  - the contract is no longer so painful to read

  - the performance is more reasonable.

Specifically, for the performance, here are the times I see to call
string->url on "http://www.racket-lang.org":

no contract: any/c
cpu time: 564 real time: 566 gc time: 3

weak contract: (-> (or/c string? bytes?) url?)
cpu time: 590 real time: 590 gc time: 3

strong, regexp-based contract:
(-> (or/c (not/c #rx"^([^:/?#]*):") #rx"^[a-zA-Z][a-zA-Z0-9+.-]*:") url?)
cpu time: 632 real time: 633 gc time: 5

This appears to be about a 10% slowdown for the regexp-based contract
over the weaker contract.

The `get-handle' method provides the underlying Cairo surface for
a bitmap, while the unsafe `make-handle-brush' function supports the
use of a Cairo surface as a `brush%'.

Also, add `racket/draw/unsafe/cairo-lib', which simplifies access
Cairo from external libraries. Documenting `racket/draw/unsafe/cairo'
might be better, but that's a lot more work.

b3002cfab0 add hinting configuration to `font%'
The default is that hiniting is enabled, which causes some text
metrics (notably width) to be rounded to integer values, which makes
spacing more consistent. This default is backward-compatible. The
non-default 'unaligned mode refrains from rounding, which makes metric
information scale correctly and improves output for PS/PDF (such as
Redex output).

The `text' function from `slideshow/pict' defaults to
disabling hinting --- which is consistent with its default to combine
text instead of drawing character-by-character -- so slides and Redex
inherit the improvement.

89dee6f6c1 Xrepl improvements, mainly around the treatment of module names.
* Get rid of the concept of `modspec': `getarg' now has `require' for
  require specs and `module' for a module name (the latter is what all
  previous uses of 'modspec except for ,require really needed); command
  descriptions use "<require-spec>" and "<module>", documentation
  adjusted as well.

* `module-name?' etc turn to `known-module' and `known-module-name',
  with a saner behavior, and tests to keep it sane.

* This cleans up a lot of things.  Two specific points: ,switch works
  better with toplevel-defined modules (see the corresponding change in
  the test suite), and also fixes PR 12148.

* Ensure that ,sh commands return void.

* Add tests for ,r with non-atomic require spec, and for use of $F in
  ,sh commands.

* Improved the test suite, including uses of `module+' so each file can
  be run by itself to perform a subset of the tests.

0d6b825377 add a preference to control whether or not there is an extra
pixel of space in between lines in DrRacket.

This change is based on Matthew's experience having a look
at the font setup on the three platforms.

He writes:
>  * Mac OS X: the convention seems to be to add space between lines.
>   TextEdit, for example, looks like DrRacket: the maze has spaces.
>
>   (I can't find a font that makes the maze look right, actually, even
>   if I adjust the line spacing.)
>
>  * Windows: the convention seems to be that space is built into the
>   font. DrRacket (and SirMail) draw lines more sparsely than Notepad.
>
>   Perhaps consistent with the differing conventions, the height of
>   "Courier New" at 11-pixel size is 14 on Windows, 13 on Mac OS X.
>
>  * Unix: the convention seems to be to add space. DrRacket looks like
>   the default Terminal and Text Editor programs on Ubuntu.
>
>   The maze nevertheless looks right everywhere, because the glyphs
>   extend an extra pixel above the declared bounding box!
