Initial version of semaphores both for POSIX and Windows. Includes test that detects failure of unnamed semaphores under Darwin. The whole code is still inactive.

Code to implement mp:interrupt-process in Windows:
...
* unixint.d: capture exceptions caused by page guards.
* unixint.d: to interrupt a Windows thread, set up a page guard onto the
ECL environment and in addition queue an APC call that accesses the
environment to trigger that exception.
* stacks.h: CL_CATCH_ALL uses _try/_except to enforce ECL's exception
handler. Without it, Windows behaves randomly and sometimes uses the
default handler and sometimes it simply aborts.
* threads.d: we use ordinary handlers to identify threads.
* time.d: SLEEP now uses Windows' SleepEx, leaving the thread in an
alertable state -- that is, it can be interrupted.
* top.lsp: fixed and improved the code that handles console interrupts,
by first using ordinary conditions and then using an interactive
query function to decide which process to interrupt.

New interrupt handling model:
...
* threads.d: New code to suspend and resume processes.
* threads.d: Threads are created detached with more robust code to wait
for completion.
* top.lsp: New code for handling console interrupt (Ctrl-C) allows
selectively interrupting one or more processes or continuing.
* file.d: Console streams are created in non-locking mode when needed.
* load.lsp.in: mp.lsp is always loaded.
* mp.lsp, symbols_list*: without-interrupts and the like belong in EXT
not in MP package.

unixint.d:
...
* The code that decides whether to process or queue a signal is factored into
handle_or_queue. This code is now used by both Linux and Windows handlers.
* Each Linux or Windows handler translates the signal into a lisp object that
is passed to handle_or_queue. This allows for simpler, platform independent
queueing, and in particular it enables Windows to discriminate FPE errors.

Bignum registers can not use statically allocated memory if we use GMP's own allocation/deallocation routines. This implies additional cleanup when deallocating an environment, and allowing for larger registers to decrease the pressure on the garbage collector.

Changed the routines that manipulate bignums so that they use bignum registers and free them when finished -- this should allow ECL work without changing GMP's memory functions.

ecl_namestring() takes now a second argument which is a flag and includes the possibility of enforcing that the output be a base string. This is used by chdir, which formerly failed to work because of getting an extended string from namestring.
