+ move the enum declaration for output formats near the head

of the file, so it can be used from more places;
+ make the declaration of contenttype[] more robust;
+ remove the wrappers around __xml_translate(), since they were
  used only in one place, and rename to xml_translate().
  This allows for a bit of simplifications.
+ document the output produced by the above function.

+/*! \brief Convert the input into XML or HTML.
+ * The input is supposed to be a sequence of lines of the form
+ *	Name: value
+ * optionally followed by a blob of unformatted text.
+ * A blank line is a section separator. Basically, this is a
+ * mixture of the format of Manager Interface and CLI commands.
+ * The unformatted text is considered as a single value of a field
+ * named 'Opaque-data'.
+ *
+ * At the moment the output format is the following (but it may
+ * change depending on future requirements so don't count too
+ * much on it when writing applications):
+ *
+ * General: the unformatted text is used as a value of 
+ * XML output:  to be completed
+ *   Each section is within <response type="object" id="xxx">
+ *   where xxx is taken from ajaxdest variable or defaults to unknown
+ *   Each row is reported as an attribute Name="value" of an XML
+ *   entity named from the variable ajaxobjtype, default to "generic"
+ *
+ * HTML output:
+ *   each Name-value pair is output as a single row of a two-column table.
+ *   Sections (blank lines in the input) are separated by a <HR>
+ *
