bug#23845: 25.0.95; Profiler has hard-coded window-width limits

Profiler reports are rendered using hard-coded width assumptions for
the window where the profile will be displayed:

  (defvar profiler-report-cpu-line-format
    '((50 left)
      (24 right ((19 right)
                 (5 right)))))

  (defvar profiler-report-memory-line-format
    '((55 left)
      (19 right ((14 right profiler-format-number)
                 (5 right)))))

This gets in the way when the profile is expanded, if the call tree is
so deep that the indentation of inner functions leaves no space for
their names -- in that case, the functions are not displayed in the
profile, and their names are replaced with an unhelpful ellipsis.

Making the profile adapt its width to the width of the frame will
allow the user to resize the frame and re-display the profile so as to
see the inner functions.  Alternatively, some user option to be used
as the width for rendering the profile might be another solution to
this problem.

In any case, there should be some way of displaying arbitrary deep
profiles in a way that the function names are readable in their
