Summary: Allow keyword args in dict() constructor

Initial Comment:
I sometimes use an idiom like

  def dictfromkeywords(**kwargs):
      return kwargs

  d = dictfromkeywords(
          akey = 12,
          anotherkey = "foo",
          ...etc.
  )

to conveniently build dicts with literal keys. This
patch adds this behavior to the dict constructor so one
can write:

  dict(one=1, two=2)

The patch patches Doc/lib/libfuncs.text,
Objects/dictobject.c, Lib/test/test_descr.py and Misc/NEWS

The dictobject.c patch contains an XXX comment about
something I'm not 100% sure about. Please review.

Thanks to Raymond H. for earlier comments.

Oops, the doctobject.c *doesn't* contain an XXX comment, I
was thinking of an earlier version of the patch. As far as I
can see the patch is fine as is (although Fred may want to
double check the libfuncs.tex patch).
