8449470db4 rktio: restore early SIGCHLD blocking to support Linux 
Process handling relies on SIGCHLD being blocked, but signals are
blocked per-thread in Linux, so SIGCHLD needs to be blocked before new
threads are created.

a13bfd25d0 rktio: reset non-blocking on sockets after dup 
On Linux, is appears that duping a socket doesn't give the
new one the same non-blocking option as the original.

This code is unlikely to get used, but make sure it runs just
in case Racket otherwise works on Windows 95/98.

36ca1361d9 rktio: normalize 'replace and 'truncate/replace behavior 
For `open-output-file`:

Move 'replace mode handling out of rktio and into the client.
Formerly, on Windows, 'replace mode was just 'truncate with a fallback
for permission problems, so this change makes it delete an existing
file and replace it, which is more consistent with how 'replace has
always worked on Unix.

In 'truncate/replace mode, if a truncating open fails due to a
permission error and the file exists, then try again as a 'replace.
That's how it worked on Windows before, and now it's how Unix works.

64146e94dc rktio: first cut at moving Racket OS wrappers to a library 
The world doesn't need yet another cross-platform I/O library, but
it's getting one. This one has exactly the things that Racket needs,
and pulling it out will make it reusable from other VMs while
improving the Racket code organization.

This first step just gets started.

dc14a68162 fix performance problem in expander 
For a term

 (lambda (arg-id ...) (define def-id _rhs) ... (arg-id def-id) ...)

the expander could take quadratic time in the number of `def-id`s
due to walking an environment to remove use-site scopes. (The
variant of the expander rewritten in Racket didn't have this
problem.)

* int mzrt_sema_create(mzrt_sema **sema, int init);
* int mzrt_sema_post(mzrt_sema *sema);
* int mzrt_sema_wait(mzrt_sema *sema);
* int mzrt_sema_destroy(mzrt_sema *sema);

scheme_add_atexit_closer now uses scheme_atexit.

bf83d1126d add some unsafe operations as an alternative to FFI access 
Accessing unsafe functionality through the FFI seemed like a good way
to avoid writing C code, but it made things more complicated instead
of easier, and it interacts badly with a more agressive shift away
from C (such as porting to Chez Scheme). So, add functions to the
primitive `#%unsafe` module, instead.

f43234e1cb add prop:authentic and (struct .... #:authentic ....) 
An authentic structure type is one whose instances cannot be
impersonated or chaperoned. The intended use of `prop:authentic` is to
annotate a library-private data structure where impersonators are
never needed internally for the data structure, and the declaration
lets the compiler produce less code and fewer branches by omitting
impersonator support.
