[7929] Some fixes and optimizations for work with packet guids. Author: VladimirMangos

    * Allocate only minimal required buffer size for object packet guid cache, avoid it realocation.
    * At adding aboyher buffer content copy only until wpos (really writed to buffer data)
    * In appendPackGUID check buffer size before data write.
