[3857] Alterations to DSO/shared library text in hooks documentation

The hooks framework is a Kea system that simplifies the way that
users can write code to modify the behavior of Kea. Instead of
altering the Kea source code, they write functions that are compiled
and linked into a dynamic shared object called here a shared library
(even the concepts are different they are implemented in the same
way with a common naming). The library is specified in the Kea
and linked into one or more dynamic shared objects, called here (for
historical reasons), shared libraries. The library is specified in the Kea
configuration and at run time Kea dynamically loads the library
into its address space. At various points in the processing, the component
"calls out" to functions in the library, passing to them the data is it

Kea uses the modified data in the remainder of its processing.
In order to minimize the interaction between Kea and the user
code, the latter is built independently of Kea in the form of
a dynamic shared object (or objects). Even they are conceptually
different dynamic shared objects are called here shared libraries.
These are made known to Kea through its configuration mechanism, and
Kea loads the library at run time. Libraries can be unloaded and
reloaded as needed while Kea is running.
