f114a3ae63 Refactor and optimize code for UNPACK_SEQUENCE. 
* Defer error handling for wrong number of arguments to the
  unpack_iterable() function.  Cuts the code size almost in half.

* Replace function calls to PyList_Size() and PyTuple_Size() with
  their smaller and faster macro counterparts.

* Move the constant structure references outside of the inner loops.

dd80f76265 SF patch #910929: Optimize list comprehensions 
Add a new opcode, LIST_APPEND, and apply it to the code generation for
list comprehensions.  Reduces the per-loop overhead by about a third.

30e97dbe96 SF Patch #902444: Use process scope thread on FreeBSD. System scope 
is too expensive on FreeBSD's KSE threading infrastructure and
even test_threadedimport fails on default setting.

786ea6bc23 Add pystack definition to Misc/gdbinit with some explanation of its behavior 
and add flag comments to ceval.c and main.c alerting people to the coupling
between pystack and the layout of those files.

ecfeb7f095 This is my patch #876198 plus a NEWS entry and a header frob. 
Remove the ability to use (from C) arbitrary objects supporting the
read buffer interface as the co_code member of code objects.

a72169871d SF patch #884022: dynamic execution profiling vs opcode prediction 
(Contributed by Andrew I MacIntyre.)

disables opcode prediction when dynamic execution
profiling is in effect, so the profiling counters at
the top of the main interpreter loop in eval_frame()
are updated for each opcode.

1dd8309246 SF patch #864059: optimize eval_frame 
Simplified version of Neal Norwitz's patch which adds gotos for
opcodes that set "why".  This skips a number of tests where the
outcome of the tests are known in advance.

b86269db45 Apply pre-sizing optimization to a broader class of objects. 
Formerly, the length was only fetched from sequence objects.
Now, any object that reports its length can benefit from pre-sizing.

1d7323e4e7 Py_Finalize(): disabled the second call of cyclic gc, and added extensive 
comments about why both calls to cyclic gc here can cause problems.

I'll backport to 2.3 maint.  Since the calls were introduced in 2.3,
that will be the end of it.

6c9e130524 - Removed FutureWarnings related to hex/oct literals and conversions 
and left shifts.  (Thanks to Kalle Svensson for SF patch 849227.)
  This addresses most of the remaining semantic changes promised by
  PEP 237, except for repr() of a long, which still shows the trailing
  'L'.  The PEP appears to promise warnings for operations that
  changed semantics compared to Python 2.3, but this is not
  implemented; we've suffered through enough warnings related to
  hex/oct literals and I think it's best to be silent now.

a690a9967e * Migrate set() and frozenset() from the sandbox. 
* Install the unittests, docs, newsitem, include file, and makefile update.
* Exercise the new functions whereever sets.py was being used.

Includes the docs for libfuncs.tex.  Separate docs for the types are
forthcoming.
