Summary: GOB: 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\gob\draw.cpp(331): warning C6011: Dereferencing NULL pointer 'coord2'
d:\sources\scummvm\scummvm\engines\gob\draw_playtoons.cpp(154): warning C6259: Labeled code is unreachable: '(<expression> & 0xff)' in a switch-expr cannot evaluate to '0xffffffffffffffff'
d:\sources\scummvm\scummvm\engines\gob\game.cpp(360): warning C6202: Buffer overrun for '_curTotFile', which is possibly stack allocated, in call to 'strcpy': length '20' exceeds buffer size '14'
d:\sources\scummvm\scummvm\engines\gob\game.cpp(373): warning C6202: Buffer overrun for '_curTotFile', which is possibly stack allocated, in call to 'strcpy': length '20' exceeds buffer size '14'
d:\sources\scummvm\scummvm\engines\gob\game.cpp(338): warning C6001: Using uninitialized memory '_captureCounter'
d:\sources\scummvm\scummvm\engines\gob\game.cpp(322): warning C6011: Dereferencing NULL pointer '_vm->_inter->_variables'
d:\sources\scummvm\scummvm\engines\gob\sound\adlib.cpp(243): warning C6323: Use of arithmetic operator on Boolean type(s)

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/942f13a9f24b )
 - 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)
