[issue25804] Make Profile.print_stats support sorting by mutiple values

[Chiu-Hsiang Hsu]

New submission from Chiu-Hsiang Hsu:

Currently, the result of profile.run can not easily sort by mutiple values with "sort" keyword argument. Following code will work with this patch.

>>> import cProfile
>>> cProfile.run('42**42', sort=('tottime', 'stdname'))
         3 function calls in 0.000 seconds

   Ordered by: internal time, standard name

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
        1    0.000    0.000    0.000    0.000 {built-in method builtins.exec}
        1    0.000    0.000    0.000    0.000 <string>:1(<module>)
        1    0.000    0.000    0.000    0.000 {method 'disable' of '_lsprof.Profiler' objects}

>>> import cProfile
>>> cProfile.run('42**42', sort=('tottime', 'stdname'))
         3 function calls in 0.000 seconds

   Ordered by: internal time, standard name

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
        1    0.000    0.000    0.000    0.000 {built-in method builtins.exec}
        1    0.000    0.000    0.000    0.000 <string>:1(<module>)
        1    0.000    0.000    0.000    0.000 {method 'disable' of '_lsprof.Profiler' objects}


>>> import profile
>>> profile.run('42**42', sort=('tottime', 'stdname'))
         4 function calls in 0.000 seconds

   Ordered by: internal time, standard name

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
        1    0.000    0.000    0.000    0.000 profile:0(42**42)
        1    0.000    0.000    0.000    0.000 :0(exec)
        1    0.000    0.000    0.000    0.000 :0(setprofile)
        1    0.000    0.000    0.000    0.000 <string>:1(<module>)
        0    0.000             0.000          profile:0(profiler)
