Merge cmucl simple-streams

... major code shifting: simple-streams.lisp is no more; its contents
have moved into several files, each for a specific kind of stream
... file layout is now the same as cmucl pcl/simple-streams directory

... new functionality: external formats (need some work still, but
infractructure is there), string-streams

Exciting gencgc hacking: SB-SYS:WITH-PINNED-OBJECTS

When passing Lisp objects to foreign code, it is important
that GC doesn't change the object's address as the foreign
code's pointers to it won't be updated. Traditionally this is
done using WITHOUT-GCING, but that's not ideal in a threaded
system where one thread may be doing a blocking alien call and
other threads would like to continue as normal.

So, instead we shove pointers to the important objects on the
C stack where they will cause the pages pointed to to be
pinned in place using preserve_pointers. Additionally we make
a small change to gencgc to ensure that they _stay_ pinned in
subsequent GCs

On ports that use cheneygc we can't do this, so
these ports don't have threads anyway, that's not a major

Small updates to doc/internals-notes/threading-specials,
slightly larger updates to comments regarding ALLOCATION
and PSEUDO-ATOMIC macros

Documentation update to the FFI chapter

Restore the GC hooks. *BEFORE-GC-HOOKS* and *AFTER-GC-HOOKS*
are run with interrupts disabled and all other threads
paused. They should take no arguments. This means that
finalization works again: three cheers.

Remove all trace of *GC-NOTIFY-{BEFORE,AFTER,STREAM}* : if you
want to notify the user that G is being C, use a hook.

test/threads.impure.lisp contains a new test which is known
to fail. Don't feel bad about deleting it

Fix asdf-install to actually chase dependencies recursively
instead of just finding the first one then stopping. Now it
seems to be able to install Araneida

Restore inadvertently chopped line to version.lisp-expr

Merge patch from Brian Mastenbrook for better dlfoo handling

... reindent to 4 spaces;
ASSQ patch from observation by PFD sbcl-devel 2003-08-16
... (NOT (NULL PAIR)) plus explanatory comment;
Pragmatism: since not all lisps implement arrays with NIL
specialized-array-element-type, our cross-compiler version needs
to be more robust. Symptoms: building sbcl/ppc from openmcl loses
in cold-init; sbcl/sparc from sbcl-0.7.x hangs in cross-compiler
compilation of STRING
... since we don't need any (ARRAY NIL)s to cross-compile SBCL,
the answer to SIMPLE-ARRAY-NIL-P for constant-folding
purposes in the cross-compiler is always NIL.

Implement INTERRUPT-THREAD, which forces another thread to
execute a function supplied by the caller.

In the process, design a mostly entirely new scheme for
calling Lisp code as a result of a handled signal: instead of
calling into Lisp directly, frob the signal context and the
stack to arrange that the Lisp is called after the signal
handler itself has returned. This is expected to be
applicable to signal handlers generally (and will have portability
benefits), but needs them to be changed around to call it.
Presently it's used only for interrupt-thread (SIGRTMIN)
and control stack exhaustion (one branch of SIGSEGV)

In principle, all you need do to use this in other places is
call return_to_lisp_function in the signal handler, with the
context and the function object that you wish to be called.
For the x86 you also need to make sure the signal is being
handled on the alternate signal stack, otherwise you'll
overwrite your own stack frame.
