SAGA: Code analysis warnings

Description

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\saga\saga.cpp(428): warning C6308: 'realloc' might return null pointer: assigning null pointer to 'stringsTable.strings', which is passed as an argument to 'realloc', will cause the original memory block to be leaked d:\sources\scummvm\scummvm\engines\saga\saga.cpp(436): warning C6308: 'realloc' might return null pointer: assigning null pointer to 'stringsTable.strings', which is passed as an argument to 'realloc', will cause the original memory block to be leaked d:\sources\scummvm\scummvm\engines\saga\shorten.cpp(369): warning C6308: 'realloc' might return null pointer: assigning null pointer to 'lpc', which is passed as an argument to 'realloc', will cause the original memory block to be leaked d:\sources\scummvm\scummvm\engines\saga\shorten.cpp(433): warning C6308: 'realloc' might return null pointer: assigning null pointer to 'unpackedBuffer', which is passed as an argument to 'realloc', will cause the original memory block to be leaked d:\sources\scummvm\scummvm\engines\saga\shorten.cpp(467): warning C6308: 'realloc' might return null pointer: assigning null pointer to 'unpackedBuffer', which is passed as an argument to 'realloc', will cause the original memory block to be leaked d:\sources\scummvm\scummvm\engines\saga\sprite.cpp(118): warning C6308: 'realloc' might return null pointer: assigning null pointer to 'spriteList.infoList', which is passed as an argument to 'realloc', will cause the original memory block to be leaked d:\sources\scummvm\scummvm\engines\saga\actor.cpp(151): warning C6308: 'realloc' might return null pointer: assigning null pointer to '_tileDirections', which is passed as an argument to 'realloc', will cause the original memory block to be leaked d:\sources\scummvm\scummvm\engines\saga\actor.cpp(164): warning C6308: 'realloc' might return null pointer: assigning null pointer to '_walkStepsPoints', which is passed as an argument to 'realloc', will cause the original memory block to be leaked

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)
