[PATCH] Fix up discard-const warnings in s4 and tries to remove "discard_const_p"s/"CONST DISCARD"s in both s3 and s4

[Matthias Dieter Wallnöfer]

Hi all,

as suggested by abartlet, I tried to reorganize the patch in smaller 
commits (e.g. const related warnings, non-const related warnings for s4; 
const fixes without functional changes - "discard_const_p" macro, const 
fixes with functional changes for s3...). I hope I made it now easier to 
review (I know it's a very heavy patch).

Therefore I rebased it now in a different private branch here: 
http://repo.or.cz/w/Samba/mdw.git?a=log;h=refs/heads/const

If you have comments and need parts of the patch contents in form as an 
e-mail I'm happy to post them.
