Definition for managing Linux console keymap files.

This adds a definition console::keymap::mapfile for installing (or
removing) keymap files for the Linux VGA console.

There is also a class console::keymap::params for defining where
keymap files are stored, with suitable defaults for some Linux
distributions.

+/*
+ * Manage (install or remove) Linux console keymap files.
+ *
+ * Parameters:
+ *  - name		Name under which the keymap file will be installed.
+ *			The suffix ".map" will be added to $name.
+ *  - ensure		One of 'present' (the default) or 'absent'.
+ *  - layouttype	The keyboard layout type which this keymap file
+ *			uses.  This governs which subdirectory the file is
+ *			installed in; typically something like "sun" or
+ *			"i386/azerty".
+ *  - source, content	Where the content of the installed keymap file will
+ *			come from.  These have the same meanings as the
+ *			corresponding parameters to the 'file' type.
