Fixed Tls initialization problem

TSK_FS_INFO must be deallocated via tsk_fs_free

Added additional calls to registerError() in auto_db.cpp

Added private method to TskImgDBPostgreSQL that looks for an existing module based on its name and returns the module id. This method is called by TskImgDBPostgreSQL::addModule() to initially check if the module already exists. If the module does not exist we attempt to insert. This insert attempt may fail if another node in a distributed environment creates the module entry. In that case we again fall back on the new getModuleId() method.

Otherwise the critical section in TSK_FS_INFO is not freed

Visual Studio optimization removes GetTlsIndex class constructor execution in release builds, due to it's not used anywhere. So the previous code has never initialized tlsIndex variable with anything. Such behavior sometime caused the crashes due to error code was not saved into unallocated TLS. 
I've made the explicit calls of GetTlsIndex methods to force class instance creation.
p.s. You may see it yourself how TlsGetValue() fails each time by running the release build under MS Application verifier.
