interrupt-thread takes another tottering step towards correctness (now
works, it seems, unless GC kicks in at wrong time)

- missing prototype for alloc_cons was causing 32 bit truncation
(thanks jsnell)
- arrange_return_to_lisp_function wasn't restoring regs correctly
(hypothetical function arguments were passed in registers, so
don't pop them from stack)

First attempt (non-working but ought to in principle, I think,
probably) at implementing interrupt-threads using pthreads.

Two known issues:

1) The immediate and pressing reason it doesn't work is that something
in interrupt_thread is lopping off the high word of the return value
from alloc_cons before storing it in th->interrupt_fun. This is
undoubtedy some problem with abuse of C's static typechecking, but I
cannot presently see what. You can observe this with something as
simple as

(sb-thread:make-thread (lambda () (sleep 60)))
(sb-thread:interrupt-thread * #'break)

2) GC does not know about this thread->interrupt_fun slot and should
be told, in case it relocates the list between signal issuance (is
that a word?) and delivery.

signal handling and thread reaping. note this won't build on non-pthreads machines, I'll sort that portability stuff out before merging. passess all threads.impure tests except for the interrupt-threads tests. backtraces are broken

trampolines must be 8-byte aligned, else their addresses are not fixnum and gc blows up on fdefns that refer to them

Maybe speed up PCL a tiny bit more
... make the slot positioning a little less confusing, so that
the 'same' slot tends to be in the same location;
... this should help the clever DFUN mechanism to keep neat ones
like ONE-INDEX around;
... (also this puts slots in objects in the 'expected' order --
frob sb-aclrepl's dealing with the unexpected

Repetitive code is the enemy of comprehension
... refactor %COERCE-CALLABLE-TO-FUN use in REDUCE and other

Certain Aarguments to sequence functions that can be functions or
function names. Coerce them to functions once instead of each time
they are applied (similar to an earlier enhancement of REDUCE).

Maybe fix compile-file performance regression
... only bind restarts for output where there is a possibility
of an encoding error. In particular, do not bind the
OUTPUT-NOTHING restart for binary IO.

Refactor sign-extension of signed c-call return values on x86-64:
* Also sign extend short ints (fixes bug reported by Kevin Rosenberg
on sbcl-devel, "FFI size error in sbcl-amd64").
* Move the sign-extension to a :naturalize-gen alien-type-method.
* Remove signed-byte-32 ptype (used only for some sign-extension
hacks, which have now been removed).
* Add some tests.

Implement fixed-format floating point through FLONUM-TO-DIGITS.
Essentially this means a whole heap of hairy logic in
FLONUM-TO-STRING, and the deletion of the Steele & White
Dragon algorithm.

... fixes (format nil "~@F" 1.23)
... fixes (format nil "~3F" -0.0)
... fixes (format nil "~G" 1d23)
... fixes (format nil "~E" 1d23)
... fixes bug 317
... does not fix bug 19, which I think is not a bug
... fixes all sorts of other stuff

It probably also breaks something, because test coverage of
this area is definitely patchy.

Fix x86-64 GC error (reported by Kevin Rosenberg on sbcl-devel,
"Regression error sbcl-amd64 with CLSQL test suite").

* The alien stack was aligned on four byte boundaries, so the
contents of *ALIEN-STACK*'s value slot could sometimes look
like an (invalid) header word. Align to eight bytes instead.
