[PATCH 0/4] MR5483: server: Correctly align 64-bit integer types in protocol.def.

[Jinoh Kang (＠iamahuman)]

__int64 has an inconsistent alignment: 4 bytes on Unix, 8 bytes on PE.

Fix this by using INT64/UINT64 which has consistent alignment on both
Unix and PE side.

This allows adding 64-bit fields at unaligned offset in the future,
without triggering struct layout mismatch between Unix and PE due to
inserted padding (which exists on PE but not on Unix).
