Revert r983, use a cast to get rid of the compiler warning:
A string is serialized as [int, chars...] with the int specifying the number of chars that follow. We must not change the int to something else! At least not without also adjusting the string read serialization and providing a way to read the old format as well.

Switch to the proper variable size.

This fixes a Win32 compiler warning.

(Fixes issue #419) : Some expression always TRUE/FALSE. Unsigned type value is always >= 0

Remove the "using namespace std" statements and explicitly refer to the std namespace where needed.

Make the serializer use only fixed types which are the same for 32-bit and 64-bit versions.
(Closes issue #387) : use the same data files for 32- and 64-bit versions

Use smart pointers for allocating memory and fix a few memory leaks while doing so.
Also replace our custom auto_buffer with std::unique_ptr<>.

Fix compiler warnings for the x64 build.
