dev-manual: Added "Properly Versioning Pre-Release Recipes" section.
Fixes [YOCTO #6243] This section addresses situations when working with recipe file names of recipes that have not been released (e.g. recipe-name_1.0.3.rc1). When the recipe is released the system has difficulty recognizing the new recipe name as a later version. So the work-around is to use PV to set the recipe version in the recipe. The section describes this.

2154 Sometimes the name of a recipe can lead to versioning
2155 problems when the recipe is upgraded to a final release.
2156 For example, consider the
2157 <filename>irssi_0.8.16-rc1.bb</filename> recipe file in
2158 the list of example recipes in the
2159 "<link linkend='new-recipe-storing-and-naming-the-recipe'>Storing and Naming the Recipe</link>"
2160 section.
2161 This recipe is at a release candidate stage (i.e.
2162 "rc1").
2163 When the recipe is released, the recipe filename becomes
2164 <filename>irssi_0.8.16.bb</filename>.
2165 The version change from <filename>0.8.16-rc1</filename>
2166 to <filename>0.8.16</filename> is seen as a decrease by the
2167 build system and package managers, so the resulting packages
2168 will not correctly trigger an upgrade.

2171 <para>
2172 In order to ensure the versions compare properly, the
2173 recommended convention is to set
2174 <ulink url='&YOCTO_DOCS_REF_URL;#var-PV'><filename>PV</filename></ulink>
2175 within the recipe to
2176 "&lt;previous version&gt;+&lt;current version&gt;".
2177 You can use an additional variable so that you can use the
2178 current version elsewhere.
2179 Here is an example:
2180 <literallayout class='monospaced'>
2181 REALPV = "0.8.16-rc1"
2182 PV = "0.8.15+${REALPV}"
