When switching tabs while an on-reflow initiated callback
might still be running can lead to bogus information
coming back from position-locations, as the editor loses
its admin.
So, we just give up recomputing the rectangles when the
admin is gone and, for now, expect that there will be
another on-reflow call when the admin comes back that'll
restart the process (not sure that this is guaranteed tho)

Changes the implementation of highlight-range so that it
only recomputes all of the new locations from the positions
when on-reflow is called (otherwise only computing the
relevant ones) and make the on-reflow callback chop itself
up, in case there are lots of highlighted ranges to avoid
tying up the event loop.
Changes searching so that it doesn't neccessarily compute
the entire search results in a single event callback
(but also make it start the computation more aggressively)
Overall, this changes the strategy from one that, for any potentially
long-running callback, just tried to push it off into the future, into
a strategy that tries to avoid long-running callbacks by breaking the
work up into chunks, but starting the first chunk immediately (in a
low-priority callback).
Also, misc other changes to make this work better and generally clean
things up.

A long time ago, I tried to improve the interactiveness
of DrRacket when the contour window was open with the
code that is removed in this commit. Looking at it today,
it seems clear that this code was buggy (and, now that
we've had lots of experience with it, it didn't actually
help with interactivity either)
The problem is that the code didn't record enough
information about the change to the editor in the thunk put
into the 'todo' field. It would remember that a particular
range was out of date, but it woudln't remember which
characters were in that range, so when it would go to copy
the characters, it may be getting the wrong characters
(since another edit may have happened since the thunk was
stored in the todo field)
This change also has the side benefit that the time it takes
to change the contour window is now being tracked by the
colorer, which means that it'll give up a bit sooner
coloring less in each go, but hopefully maintaining the
interactivity

multiple ones, try to guarantee that there is an edit sequence)

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

The set-replace-start and get-replace-search-hit methods were
missing in the text:searchable<%> interface. The latter was
also undocumented.

For example, autocomplete of `cur-dir' will produce the same list of results as the documentation search, with `current-directory' first, instead of producing no results.

line terminators when:
a) running under windows, and
b) the file on the disk (when DrRacket first opens it)
contains all CRLF line endings.
In all other situations, the file is saved with LF terminators.
Before this commit, DrRacket would always use the platform-specific
convention, regardless of the original content of the file.

then, use that to change how it works for the scheme mode (and also another variation for the REPL to
cope with the prompt)
I spent a while trying to make this work at the keymap% level (ie putting different keybindings for "home"
and "c:a" into different keymaps) but this just turned out to be far too confusing and fragile, so went
with this alternative (one keybinding, but that delegates to an overridable method)
