7eb2042bd9 fix compiler handling of top-/module-level constants 
The JIT and bytecode compiler disagreed on the definition of
"constant". Now there are two levels: "constant" means constant across
all instantiations, and "fixed" means constant for a given instantation.
The JIT uses this distinction to generate direct-primitive calls
or not. (Without the distinction, a direct jump to `reverse' could
be wrong, because `racket/base' might get instantiated with the
JIT disabled or not.)

Also, fixed a bug in the JIT's `vector-set!' code in the case that
the target vector is a top-/module-level reference that is ready,
fixed, or constant.

8eefaba187 fix `regexp-match' performance for short matches on long strings 
More specifically, for a string of length N and a match that
only looks at the first M characters, the complexity of
`regexp-match' is now O(M) instead of O(N). This allows
`regexp-split' to be O(N) for a string instead of O(N^2).

Also, fixed a bug in non-greedy matching that could affect
both long strings and input ports.

f297c98c1a Heavily revise this test. 
- Simplify code
- Remove bogus leftover (tests) in the end
- Resolve deadlock that resulted from using `tcp-abandon-port' in
  `net/ftp'
- Actually there's no need for threads, probably because of small size
  of data, so keep it.
- Use scribble syntax instead of here-strings, and move the text out of
  the way.

Matthew Flatt
3b031d6c87 `define' + keyword lambda at top/module level => static checking 
When `define' binds a keyword procedure at the top level or module
level, then it actually binds syntax that checks (i.e., warns
if arith or keywords are bad) and optimizes (i.e., avoids checking
keywords or allocating keyword-argument lists) first-order uses of
the procedure.

Checking and conversion are currently only performed for top-
and module-level bindings, because some macros detect the difference
between a variable or syntax definition --- notably `class' and
`unit'. A related problem in `class' is that the expansion
produces multiple definitions (for direct access to the fast
version of the function), which `class' turns into fields instead
of methods.

b7afb3cf8f Scribble: support for "boxable" blocks in Latex output 
For example, if you make a multi-column table with a
`racketblock' in each column, then the columns size
to fit the code --- instead of forcing the table width
to match the page width and forcing each column to take
an equal share width.

4ac85de974 Scribble: style adjustments to deter code wrapping 
For HTML, the style used in the output of `racketblock' now
disables line wrapping, and the Rkt text styles inherit
line-wrap behavior. This doesn't solve the general problem
of code overflowing the horizontal space, but it makes the
failure mode usefully better.

A new 'vertical-inset nested-flow style is used by
`defproc', `defform', etc. It has no effect for HTML,
but it introduces suitable vertical space for Latex output
(in case you want to use `defproc' in a SIGPLAN-format
paper, for example).

d048954f04 Poll mirrors for the download web pages. 
This is triggered by an environment variable that points at a file that
is used to cache polling results.  If the variable is not specified just
use all mirror links as usual.  This way, for random builds when people
try things out there is no problem, while the nightly builds (and my
manual builds when there are changes) do the right thing.

The file holds information about the polls, and verifies that the
download exists -- if not, the link is not shown.  If it is, then it
tries to get the size of the remote file (via HEAD or via FTP), and if
it doesn't match our download information, then drop it too.  If no size
informaion is available, include it, but re-poll after a few days.  Even
if the size matches, a re-poll will be done after a month, so stale
mirrors will not stick.

6a1336e75e Return a file size string when possible. 
This takes the advice from
  http://files.stairways.com/other/ftp-list-specs-info.txt
further: search for the date by an explicit occurrence of a known month
name.  This means that we won't see files with bad names (they'd be
filtered out of the result), but the filtered out entries are ones that
would not be usable with `ftp-make-file-seconds'.

When the month is found, and the entry is a file, look for a number
preceding the month, and if found, return it as the file size string.
This is a minor change in the API.  (But it's probably better to either
revise it further, or eventually make it irrelevant by exposing the
interesting functionality via `net/url'.)

234015b34d Make `ftp-make-file-seconds' use a correct year instead of 2002. 
This function was using 2002 when there's no year...  Updated it to use
the last occurrence of the guessed date, as described at
  http://files.stairways.com/other/ftp-list-specs-info.txt

This function still looks pretty bogus -- the RFC does *not* say
anything about the format of response to `LIST', so it's whatever
semi-random thing the server does.  (The above link looks like an
attempt to fix it, but I didn't see anything more official than that.)
From some looking around, it looks like ftp clients just try a bunch of
patterns against the text.  Add also warnings in the documentation about
this.

ba48669ead Use UTF-8 and CRLF in the ftp client 
RFC 2640 specifies that all transport strings are assumed UTF-8 if they
can be parsed as such.  To make this complete it should really send a
FEAT and check that the result has "UTF8", but it's kind of redundant
since there's not much else to do if it isn't.

Also, switch to a more correct line endings of CRLF when sending
messages to the server.

b972a0940d Added online expansion and compilation of files 
being edited in DrRacket (via places)

Added an API to let tools have access to that
  information (and compute more stuff)

Used that to make an online version of Check Syntax
  which led to a separately callable Check Syntax API.

ec27cbfd90 fix problems related to futures and is-list flags on pairs 
Although a future thread used an atomic compare-and-swap to
set "is a list" or "not a list" flag on pairs via the
JIT-implemented `list?', the hashing function in the runtime
thread did not; as a result, it might be possible to lose
a hash code due to cache inconsistency (although I'm not
sure it's actually possible, and I couldn't trigger a problem
with a test). Most of the changes are related to using
an atomic compare-and-swap when setting a hash code, as
well as clean-ups to related code. Processor-count tests
avoid using atomic compare-and-swap on uniprocessors, which
might not support the relevant machine instructions.

As significantly, the compare-and-swap operation for the
JIT-implemented `list?' did not actually set flags on
a pair that has a hash code. This could lead to `list?'
tests that were not constant time (but only if the relevant
pair's `eq?' hash code had been used previously).

9ace663021 Racket-implemented reverse', member', memv', memq' 
With the JIT, the `reverse' function is significantly faster,
while the `member' variants do not really change; the main
benefit is that the operations play well with futures.

The C implementation is still used when the JIT is unavailable,
since the Racket implementations can be much slower in
interpreted mode.

69f7e912d2 cocoa: fix problems with sheets and focus 
Avoids a problem with the file dialog when a sheet is the
current "main window" (Cocoa terminology); when the file
dialog is closed, both the sheet owner and the sheet
become the main window (in that order), so that when the
sheet goes away, the sheet owner doesn't become the main
window as it should. It seems like a Cocoa problem. The
workaround is to hook into the callback that says a
sheet went away.
