Fix issue10377 - Output from pstats - it is just secs (i.e, wallclock time) and not CPU time.

Add another news entry.
........
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!
Most of this code was old enough to vote. Examples of cleanups:
+ Backslashes were used for line continuation even inside unclosed
bracket structures, from back in the days that was still needed.
+ There was no use of % formats, and e.g. the old fpformat module was
still used to format floats "by hand" in conjunction with rjust().
+ There was even use of a do-nothing .ignore() method to tack on to the
end of a chain of method calls, else way back when Python would print
the non-None result (as it does now in an interactive session -- it
*used* to do that in batch mode too).
+ Perhaps controversial (although I can't imagine why for real <wink>),
used augmented assignment where helpful. Stuff like
self.total_calls = self.total_calls + other.total_calls
is just plain harder to follow than
self.total_calls += other.total_calls
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").
There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)

Here is batch 2, as a big collection of CVS context diffs.
Along with moving comments into docstrings, i've added a
couple of missing docstrings and attempted to make sure more
module docstrings begin with a one-line summary.
I did not add docstrings to the methods in profile.py for
fear of upsetting any careful optimizations there, though
i did move class documentation into class docstrings.
The convention i'm using is to leave credits/version/copyright
type of stuff in # comments, and move the rest of the descriptive
stuff about module usage into module docstrings. Hope this is
okay.
