Add counting of segment lengths of segmented callback list. This will be useful for a number of things such as knowing how big the ready-to-execute segment have gotten. The immediate benefit is ability to trace how the callbacks in the segmented callback list change. Also this patch remove hacks related to using donecbs's ->len field as a temporary variable to save the segmented callback list's length. This cannot be done anymore and is not needed. Also fix SRCU: The negative counting of the unsegmented list cannot be used to adjust the segmented one. To fix this, sample the unsegmented length in advance, and use it after CB execution to adjust the segmented list's length.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
