[PATCH 07/18] doc: Improve "Library" chapter, moving "Types of Compositor" as its section

[Peter Hutterer]

From: Tiago Vignatti <tiago.vignatti at intel.com>

It was added a "Server API" section and "Types of Compositor" was moved there
also. I hope this gives a better structure for the documentation.

+  The open-source reference implementation of Wayland protocol is split in two

+  <emphasis>libwayland-client</emphasis>. Their main

+  <para>
+  This Chapter describes in detail each library's methods and their helpers,
+  aiming implementors who can use for building Wayland clients and servers;
+  respectively at <xref linkend="sect-Library-Client"/> and
+  <xref linkend="sect-Library-Server"/>. The last
+  <xref linkend="sect-Compositors"/>, gives an example how
+  <emphasis>libwayland-server</emphasis> can be used for building different
