Add `raise-argument-error', `raise-result-error', `raise-arguments-error',
and `raise-range-error'.
The old convention was designed for reporting on a single (sometimes very
long line). The new convention is
<name>: <short message>
<field>: <detail>
...
If <detail> is long or itself spans multiple lines, then it may
also use the form
<field>:
<detail>
where each line of <detail> is indented by 3 spaces.
Backtrace information is shown as a multi-line "context" field.

The prohbition against `handle-evt' on `handle-evt' is as
document and as originally intended. I'm not sure why it
was allowed.
Existing programs that use `handle-evt' incorrectly
can break. I found and fixed one incorrect use and one
questionable use in the Racket tree (which is a small
minority of the uses of `handle-evt' in the tree).

There is a big comment in thread.rkt that explains the problem and the
"fix". I think something better could and should be done, but I don't
know what it is.

* Move the `X-Mailer' header to the top, so that the interesting headers
are all together at the bottom (the top gets littered by server
headers anyway).
* Use `subprocess' directly (`process*' wasn't really doing anything
more than that).
* Allow the sender to be `#f', leaving the header out. This makes all
sendmails that I've used use the username that is running the process.
* Just search for a sendmail program: don't barf on windows, so it can
be used in case there is a sendmail.exe executable there.
* Remove `no-mail-recipients' to make it in-line with other racket code
that doesn't raise super-specific exceptions.
* Use port counting instead of doing the counts manually, much simpler
code.

This library is used by Redex, which wants a `syntax'-like template
language, but for datum values instead of syntax objects. Using
`datum-case' and `datum' generates much less code. Redex uses
only a small part of the general functionality, so adding
`syntax/datum' could be overkill. It's implemented by generalizing
the `syntax-case' and `syntax' pattern matching and template
constructing code, though; it's not a lot of extra code, and it's
easiest to generalize completely. We may find other uses for
datum templates, too.

The `date*' structure type is an extension of `date' with
`nanosecond' and `time-zone-name' fields.
The `seconds->date' function now accepts a real and returns a
`date*'. The fractional part of its argument goes into the
`nanosecond' field.

Macros and other tools that need syntax privilege used
`(current-code-inspector)' at the module top-level to try to
capture the right code inspector at load time. It's more
consistent to instead use the enclosing module's declaration-time
inspector, and `var-ref->mod-decl-insp' provides that. The
new function works only on references to anonymous variables,
which limits access to the inspector.
The real function name is longer, of course.
