- Separated the actual DVB hardware OSD implementation from the abstract OSD
  interface. 'osdbase.c/.h' now implements the abstract OSD, while 'dvbosd.c/.h'
  is the actual implementation for the DVB hardware. This is in preparation for
  allowing additional kinds of OSD hardware implementations.
- Fixed leftover references to the file FORMATS in MANUAL and svdrp.c.
- Avoiding ambiguities in the cList template class in case one defines a "list of
  lists" (thanks to Stefan Huelswitt).
- Simplified the basic cMenuSetupPage class for easier use in plugins.
- Added setup parameters and a Setup menu to the 'hello' plugin example.
- Fixed logging error message for unknown config parameters in plugins.
- Rearranged cleanup sequence at the end of the main program.
- Adapted PLUGINS.html to use the actual code examples from the 'hello' plugin.

<!--X1.1.1--><table width=100%><tr><td bgcolor=red>&nbsp;</td><td width=100%>
Header files usually contain preprocessor statements that prevent the same
file (or rather its contents, to be precise) from being included more than once, like
<p><table><tr><td bgcolor=#F0F0F0><pre><br>
#ifndef __I18N_H
#define __I18N_H
...
#endif //__I18N_H
</pre></td></tr></table><p>
The example shown here is the way VDR does this in its core source files.
It takes the header file's name, converts it to all uppercase, replaces the
dot with an underline and preceedes the whole thing with two underlines.
The GNU library header files do this pretty much the same way, except that they
usually precede the name with only one underline (there are exceptions, though).
<p>
As long as you make shure that none of your plugin's header files will be named
like one of VDR's header files, you can use the same method as VDR. However,
if you want to name a header file like one that is already existing in VDR's
source (<tt>i18n.h</tt> would be a possible candidate for this), you may want
to make sure that the macros used here don't clash. How you do this is completely
up to you. You could, for instance, prepend the macro with a <tt>'P'</tt>, as in
<tt>P__I18N_H</tt>, or leave out the trailing <tt>_H</tt>, as in <tt>__I18N</tt>,
or use a completely different way to make sure a header file is included only once.
<p>
The 'hello' example that comes with VDR makes use of <a href="#Internationalization">internationalization</a>
and implements a file named <tt>i18n.h</tt>. To make sure it won't clash with VDR's
<tt>i18n.h</tt> it uses the macro <tt>_I18N__H</tt> (one underline at the beginning
and two replacing the dot).

<a name="The Setup menu"><hr><h2>The Setup menu</h2>
<center><i><b>Have it your way!</b></i></center><p>
To implement a <i>Setup</i> menu, a plugin needs to derive a class from
<tt>cMenuSetupPage</tt> and implement its constructor and the pure virtual
<tt>Store()</tt> member function:
<p><table><tr><td bgcolor=#F0F0F0><pre><br>
int GreetingTime = 3;
int UseAlternateGreeting = false;
class cMenuSetupHello : public cMenuSetupPage {
private:
int newGreetingTime;
int newUseAlternateGreeting;
protected:
virtual void Store(void);
public:
cMenuSetupHello(void);
};
cMenuSetupHello::cMenuSetupHello(void)
{
newGreetingTime = GreetingTime;
newUseAlternateGreeting = UseAlternateGreeting;
Add(new cMenuEditIntItem( tr("Greeting time (s)"), &amp;newGreetingTime));
Add(new cMenuEditBoolItem(tr("Use alternate greeting"), &amp;newUseAlternateGreeting));
}
void cMenuSetupHello::Store(void)
{
SetupStore("GreetingTime", GreetingTime = newGreetingTime);
SetupStore("UseAlternateGreeting", UseAlternateGreeting = newUseAlternateGreeting);
}
</pre></td></tr></table><p>
In this example we have two global setup parameters (<tt>GreetingTime</tt> and <tt>UseAlternateGreeting</tt>).
The constructor initializes two private members with the values of these parameters, so
that the <i>Setup</i> menu can work with temporary copies (in order to discard any changes
if the user doesn't confirm them by pressing the "Ok" button).
After this the constructor adds the appropriate menu items, using internationalized texts
and the addresses of the temporary variables. That's all there is to inizialize a <i>Setup</i>
menu - the rest will be done by the core VDR code.
<p>
Once the user has pressed the "Ok" button to confirm the changes, the <tt>Store()</tt> function will
be called, in which all setup parameters must be actually stored in VDR's global setup data.
This is done by calling the <tt>SetupStore()</tt> function for each of the parameters.
The <i>Name</i> string given here will be used to identify the parameter in VDR's
<tt>setup.conf</tt> file, and will be automatically prepended with the plugin's name.
<p>
Note that in this small example the new values of the parameters are copied into the
global variables within each <tt>SetupStore()</tt> call. This is not mandatory, however.
You can first assign the temporary values to the global variables and then do the
<tt>SetupStore()</tt> calls, or you can define a class or struct that contains all
your setup parameters and use that one to copy all parameters with one single statement
(like VDR does with its cSetup class).
