ref-manual: New variable entries added. 

* EXTERNALSRC
* EXTERNALSRC_BUILD

These are new.

Also fixed a link to the dev-manual that points to the section
on how to use external.bbclass.  The section name was changed
so that it does not imply how to use the class.

(From yocto-docs rev: be9b801cac6a8fd6cd3db86eacf432f73da6fd08)

When a recipe inherits
<filename>externalsrc.bbclass</filename>, this
variable points to the source tree, which is
outside of the OpenEmbedded build system.
When set, this variable sets the
<link linkend='var-S'><filename>S</filename></link>
variable, which is what the OpenEmbedded build system uses
to locate unpacked recipe source code.
