RCU consolidation effort causes the update side of the RCU API to be consistent across all the 3 RCU flavors (normal, sched, bh). This commit therefore updates the full API in the whatisRCU document, thus encouraging people to use the consolidated RCU update API instead of the old RCU-bh and RCU-sched update APIs. Also rcu_dereference is documented to be the same for all 3 mechanisms (even before the consolidation), however its actually different - as using the right rcu_dereference primitive (such as rcu_dereference_bh for bh) is needed to make lock debugging work correctly. This update also corrects that. Also, add local_bh_disable() and local_bh_enable() as softirq protection primitives and correct a grammar error in a quiz answer.

README
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.
