leaks this patch fixes.
* Instead of having FD-STREAM objects directly hold onto input and
output buffer SAPs and head/tail indexes, use BUFFER objects which
contain the SAP, size of the memory area, head/tail indexes, and
are have finalizers to deallocate the system memory assosicated
with the SAP. (This fixes system memory leaks when streams are not
properly closed.)
* Make CLOSE :ABORT release the output queue associated with the
stream. (This was another memory leak in the old system: now
the finalizers make not doing this safe, but it's still better
to recycle the buffers.)
* Slightly reduce lock contention by grabbing the *AVAILABLE-BUFFERS*
lock only if there is something there right before the lock is
taken, and by doing allocation outside the lock.
* Rename and refactor FROB-OUTPUT and friends:
BUFFER-OUTPUT is the main interface function, which always
adds new output to the current buffer / output queue.
WRITE-OR-BUFFER-OUTPUT tries to write immediately, falling
back to buffering if writing is not possible.
WRITE-OUTPUT-FROM-QUEUE is called by the SERVE-EVENT
system to deal with output queue.
FLUSH-OUTPUT-BUFFER writes the current buffer out if possible,
queues it otherwise. Ensures that the output buffer of

1.0.7.17: SLOT-VALUE and SET-SLOT-VALUE transforms (really 1.0.7.16)
This is the real commit message that was supposed to go in 1.0.7.16.
Sorry.
* Define SLOT-VALUE and SET-SLOT-VALUE as known functions.
* Use &ENVIRONMENT in CONSTANTP and CONSTANT-FORM-VALUE calls in
their compiler-macros.
* Add transforms for SLOT-VALUE and SET-SLOT-VALUE in addition to the
compiler-macros. The transforms are functionally equivalent to the
compiler-macros, but catch more cases: eg.
(define-modify-macro appendf (&rest lists) append)
(appendf (slot-value x 'y) z)
needs the deftransforms as setf-expansion replaces the constant
argument with a gensym.
Keep the compiler-macros around, since they catch the common cases
early and don't mess up the build: the transforms are agressive
enough that we can't enable them until the PCL boot-state is
complete. (The compiler-macros are also slightly cheaper, since
each transform introduces a new lambda.)

1.0.7.2: fix potential GC errors due to bogus objects in backtraces
Backtrace construction involves calling MAKE-LISP-OBJ on things we
devoutly hope are tagged lisp pointers, but this is not always the
case. When we fail to detect this, and a GC follows while the bogus
object is at location visible to GC bad things will happen. (Pinning
doesn't change anything, as the object still needs to be scavenged.)
To fix this (mostly -- one can still construct bogus lisp-objects
using MAKE-LISP-OBJ, it just takes more work / is less likely to
happen by accident):
* Rename MAKE-LISP-OBJ %MAKE-LISP-OBJ, and MAKE-VALID-LISP-OBJ
MAKE-LISP-OBJ.
* Add an optional ERRORP argument to the former MAKE-VALID-LISP-OBJ,
defaulting to T.
* Always use the function formerly known as MAKE-VALID-LISP-OBJ,
passing in errorp=NIL when in doubt.
* Improve the validation done on x86/x86-64: factor out the checking
logic in possibly_valid_dynamic_space_pointer, and use it to
implment valid_lisp_ponter_p. Could be done on other platforms as
well, but better done by someone who can test the results...
Adjust other code to suit:
* MAP-ALLOCATED-OBJECTS uses %MAKE-LISP-OBJ for now, as the new
MAKE-LISP-OBJ is too slow to use for groveling over the whole
heap. (Though it does detect a bunch of bogus objects we're
constructing in ROOM now, so the time would not be really
wasted...)
No test cases because I've been unable to construct one that calls
MAKE-LISP-OBJ with bogus arguments while backtracing, but such
backtraces have been seen in the wild.
