45b8e103e5 places: fix GC of unreceived place-channel messages 
An unreceived message can have a reference to a master-allocated
value, in which case that value must be marked. This marking
is implemented by embedding a linked link within the message
memory.

eb25a2db47 add epoll() support for Linux, kqueue() support for BSDs 
This change builds on the blocking-I/O change to provide substantially
better performance when waiting on lots of sockets.

67df1f7bce change handling of blocking I/O to collapse sources to a single poll 
This improvement applies to both poll() and select() modes, and it
can reduce scheduling overhead when blocking on many I/O sources
at once.

This mode is not enabled for Windows, however, since Racket doesn't
exactly use select() on Windows.

646f7e70e7 prefer poll() to select() on Linux 
On Mac OS X, poll() doesn't work right in versions earlier than 10.5.5,
select() is always faster, and large number of sockets will be
better handled via kqueue(). On Linux, poll() is defintely better.
Otherwise, we stick with select() to be conservative.

35526a7bd7 fix JIT early reference to JIT generated address 
On x86_64, if the scratch-space address fits into 32
bits and the final place for shared code doesn't
fit into a 32-bit address, then the size of the generated
code could change, leading to a JIT buffer overflow.

5c0956d7b1 more memory accounting fixes for places 
Fix memory accounting to detect when messages pile up in a
place channel and when shared values (such as the result of
`make-shared-bytes') pile up. Also fix problems where a GC
or free-page purge needs to be triggered.

The implementation causes a minor API change, which is that
a place channel sent multiple times as a message generates
values that are `equal?' but no longer eq?'.

6a8d3c34f1 win64: avoid msvcr90.dll 
The libjpeg, libeay, and ssleay libraries for Win64 linked to
msvcr90.dll, because of the way that they were compiled with
MSVC 2008, but msvcr90.dll is not included with Win7, and
redistributing it is problematic. The new variants of the libraries
link instead of msvcrt.dll --- which you're not supposed to do
according to MS, but that's the way libraries like Gtk are
built, and it seems to be the right approach. See also

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.
