Raymond Hettinger fd7ed407d7 Give meaning to the oparg for BUILD_MAP: estimated size of the dictionary.
Allows dictionaries to be pre-sized (upto 255 elements) saving time lost
to re-sizes with their attendant mallocs and re-insertions.

Has zero effect on small dictionaries (5 elements or fewer), a slight
benefit for dicts upto 22 elements (because they had to resize once
anyway), and more benefit for dicts upto 255 elements (saving multiple
resizes during the build-up and reducing the number of collisions on
the first insertions).  Beyond 255 elements, there is no addional benefit.

Raymond Hettinger effde12f5f Speed-up dictionary constructor by about 10%.
New opcode, STORE_MAP saves the compiler from awkward stack manipulations
and specializes for dicts using PyDict_SetItem instead of PyObject_SetItem.

Christian Heimes 8affb5f236 Fixed for #1601: IDLE not working correctly on Windows (Py30a2/IDLE30a1)
Amaury's ideas works great. Should we build the Python core with WINVER=0x0500 and _WIN32_WINNT=0x0500, too?

is now simpler.  Thanks Mark Dickinson.

Raymond Hettinger 6c87af5d87 Optimize PyList_AsTuple(). Improve cache performance by doing the
pointer copy and object increment in one pass.  For small lists,
save the overhead of the call to memcpy() -- this comes up in
calls like f(*listcomp).

Gerhard Häring 99b9df8e11 Forward-port of commit 59184.
- Backported a workaround for a bug in SQLite 3.2.x/3.3.x versions where a
  statement recompilation with no bound parameters lead to a segfault
- Backported a fix necessary because of an SQLite API change in version
  3.5.
  This prevents segfaults when executing empty queries, like our test suite
  does

Christian Heimes f15c66e143 The new float repr causes too much trouble and pain. I'm disabling the feature until we have sorted out the issues on all machines. 64bit machines seem to have issues and Guido has reported even worse.
Guido: It's pretty bad actually -- repr(1e5) comes out as '1.0'... Ditto for
repr(1eN) for most N... Both in 2.6 and in 3.0...
