Summary: SWORD2: Code analysis warnings

Initial Comment:
Here are the warnings I get when compiling the engine using Code Analysis in VS2010. I tried to remove all the obvious false positives. Some warnings look suspicious, others are pointing to correct code that still might benefit from better error checking.

d:\sources\scummvm\scummvm\engines\sword2\music.cpp(500): warning C6308: 'realloc' might return null pointer: assigning null pointer to '_mixBuffer', which is passed as an argument to 'realloc', will cause the original memory block to be leaked
d:\sources\scummvm\scummvm\engines\sword2\protocol.cpp(415): warning C6336: Arithmetic operator has precedence over question operator, use parentheses to clarify intent
d:\sources\scummvm\scummvm\engines\sword2\protocol.cpp(416): warning C6336: Arithmetic operator has precedence over question operator, use parentheses to clarify intent
d:\sources\scummvm\scummvm\engines\sword2\render.cpp(734): warning C6336: Arithmetic operator has precedence over question operator, use parentheses to clarify intent
d:\sources\scummvm\scummvm\engines\sword2\render.cpp(735): warning C6336: Arithmetic operator has precedence over question operator, use parentheses to clarify intent
d:\sources\scummvm\scummvm\engines\sword2\resman.cpp(305): warning C6011: Dereferencing NULL pointer '_resFiles[cluFileNum].entryTab'
d:\sources\scummvm\scummvm\engines\sword2\controls.cpp(188): warning C6011: Dereferencing NULL pointer 'buf'

Note:
If you want to try it yourself, you will need:
 - the create_project patch set, along with the WIP code analysis patch (http://bitbucket.org/Littleboy/scummvm-jt/src)
 - the following patch to silence some false positives ( http://bitbucket.org/Littleboy/scummvm-jt/src/tip/COMMON%20-%20Add%20annotations%20for%20analysis%20build%20configuration.patch )
 - Visual Studio 2010 Ultimate or Team System (create_project support for analysis with VS2005/2008 isn't complete yet)
