Subject: ref-manual: Added useradd-staticids class and edits to some
 variables.

Added the new useradd-staticids class to the reference section
for classes.

Updated the USERADD_UID_TABLES and USERADD_GID_TABLES variables
to tell how the system uses BBPATH in the default mode to
get UID and GID information from the files/passwd and files/group
files.

Added a note indicating that you can delete the TMPDIR directory
to fix things up if you configure useradd-staticids in a
configured system.

(From yocto-docs rev: a3f5ee3f5060369405d59a238fb02bddfeae5d6f)

+        The <filename>useradd-staticids</filename> class supports the addition of
+        users or groups that have static user identification
+        (<filename>uid</filename>) and group identification
+        (<filename>gid</filename>) values.

+

+        The default behavior of the OpenEmbedded build system for assigning
+        <filename>uid</filename> and <filename>gid</filename> values when
+        packages add users and groups during package install time is to
+        look in
+        <link linkend='var-BBPATH'><filename>BBPATH</filename></link> for
+        <filename>files/passwd</filename> and <filename>files/group</filename>
+        files for the values.
+        This works fine for programs that do not care what the values of the
+        resulting users and groups become.
+        In these cases, the order of the installation determines the final
+        <filename>uid</filename> and <filename>gid</filename> values.
+    </para>
+
+    <para>
+        If non-deterministic
+        <filename>uid</filename> and <filename>gid</filename> values are a
+        problem, you can override the default, dynamic application of these
+        values by setting static values.
+        See the
+        <link linkend='var-USERADDEXTENSION'><filename>USERADDEXTENSION</filename></link>,
+        <link linkend='var-USERADD_UID_TABLES'><filename>USERADD_UID_TABLES</filename></link>,
+        <link linkend='var-USERADD_GID_TABLES'><filename>USERADD_GID_TABLES</filename></link>,
+        and
+        <link linkend='var-USERADD_ERROR_DYNAMIC'><filename>USERADD_ERROR_DYNAMIC</filename></link>
+        variables for more information.
+        You can also see the
+        <link linkend='ref-classes-useradd'><filename>useradd</filename></link>
+        class for additional information.

+        You do not use this class directly.
+        You either enable or disable the class by setting the
+        <filename>USERADDEXTENSION</filename> variable.
+        If you enable or disable the class in a configured system,
+        <link linkend='var-TMPDIR'><filename>TMPDIR</filename></link>
+        might contain incorrect <filename>uid</filename> and
+        <filename>gid</filename> values.
+        Deleting the <filename>TMPDIR</filename> directory
+        will correct this condition.
