[vdr] Suggestion: Simplify vdr update for modded dvb-cards

["Christoph Hermanns" <Christoph.Hermanns@web.de>]

As owner of a modded Nexus dvb-card with 4MB RAM it is a little bit nasty  
for me
to edit the dvbosd.c file every time when i want to compile a new fresh  
vdr version
and change the line 21
#define MAXOSDMEMORY  92000 // number of bytes available to the OSD  
(depends on firmware version, but there is no way of determining the  
actual value)
into
#define MAXOSDMEMORY  1000000 // for 4mb mod


I suggest to introduce a user option in the Make.config file
to change the MAXOSDMEMORY value if necessary, because i easily copy my  
personal
Make.config file from the previous vdr version to the new one i want to  
compile.

For example:

In Make.config :

MAXOSDMEMORY=1000000

and in dvbosd.c :

ifndef MAXOSDMEMORY
#define MAXOSDMEMORY  92000 // default number of bytes available to the OSD
endif


should change the behaviour as needed.
Any other suggestions are welcome of course.

Greetings,
Christoph
