Based on lsprof (patch #1212837) by Brett Rosen and Ted Czotter.
With further editing by Michael Hudson and myself.
History in svn repo: http://codespeak.net/svn/user/arigo/hack/misc/lsprof

* Module/_lsprof.c is the internal C module, Lib/cProfile.py a wrapper.
* pstats.py updated to display cProfile's caller/callee timings if available.
* setup.py and NEWS updated.
* documentation updates in the profiler section:
   - explain the differences between the three profilers that we have now
   - profile and cProfile can use a unified documentation, like (c)Pickle
   - mention that hotshot is "for specialized usage" now
   - removed references to the "old profiler" that no longer exists
* test updates:
   - extended test_profile to cover delicate cases like recursion
   - added tests for the caller/callee displays
   - added test_cProfile, performing the same tests for cProfile
* TO-DO:
   - cProfile gives a nicer name to built-in, particularly built-in methods,
     which could be backported to profile.
   - not tested on Windows recently!

call, or via setting an instance or class vrbl.
Rewrote the calibration docs.
Modern boxes are so friggin' fast, and a profiler event does so much work
anyway, that the cost of looking up an instance vrbl (the bias constant)
per profile event just isn't a big deal.

hasn't worked in years, docs were wrong, and they aren't interesting
anymore regardless.

translation more difficult, as well as reading the English more
difficult for non-native speakers.

This closes SF bug #438032.

about setting up the dispatch table, and update the OldProfile and
HotProfile classes to the current implementations, showing the adjusted
construction for the dispatch table.

Turn reference to the cmd module into a hyperlink.

All sections get reasonable file names in the HTML output.

Consistently use ' instead of ":  this conforms to my unofficial stance that
constants should be presented using the repr() whenever it makes sense.  This
isn't because I think repr() is the greatest thing since spam, just that it's
an easy to adopt consistency standard.  (It also holds no new surprises!)

Consistency nits.

particular example.

works better with LaTeX2HTML, and allows some simplification of the python.sty
macros.

checkin of myformat.sty.

Change "\renewcommand{\indexsubitem}{(...)}" to "\setindexsubitem{(...)}"
everywhere.

Some other minor nits that I happened to come across.
