framework - Find/remove useless ifdefs and dead code within them

Hi List!

Some days ago, I developed a script that can show to us all ifdefs that
don't have a "#define".

After run this script in the "framework" dir, I get this list:

ifdef ENABLE_COMPONENT_SELF_CHECK without #define. This can be removed?
ifdef DBG_UTIL without #define. This can be removed?
ifdef fpf without #define. This can be removed?
ifdef fpc without #define. This can be removed?
ifdef ENABLE_SERVICEDEBUG without #define. This can be removed?
ifdef ENABLE_TARGETINGDEBUG without #define. This can be removed?
ifdef ENABLE_REGISTRATIONDEBUG without #define. This can be removed?
ifdef ENABLE_PLUGINDEBUG without #define. This can be removed?
ifdef ENABLE_MUTEXDEBUG without #define. This can be removed?
ifdef ENABLE_FILTERDBG without #define. This can be removed?
ifdef ENABLE_EVENTDEBUG without #define. This can be removed?
ifdef ENABLE_GENERATEFILTERCACHE without #define. This can be removed?

This is the output of my script. I belive DBG_UTIL is defined in an other
way (a lot of code within this ifdefs around the LO) but I didn't notice
any define explicitly. But the others, like ENABLE_COMPONENT_SELF_CHECK,
only appears in the framework dir. After some git digs, I saw that this
ifdef was created near 2002/2003, so it seems to very very old...

Tor Lillqvist, told me that we need to get the feedback of the list,
correctly of course, and so I came here to ask you guys, what we can do
with these macros!

I belive with this script, we can remove a lot of dead code within the LO,
but I will need you feedback to verify is these macros are really
unused/dead.

If one of these macros are defined in other way, please tell me, because I
can change the script to skip these ifdefs.

When you answer me, I will send a patch removing what is dead!

Thanks since now!
