Nothing in the server writes or reads a packet by hand any more, so the
helpers for doing so go:
- CBITSTREAM, CMSGHEADER, CINSTREAM, CINSTREAM_SKIP_HEADER, SEND_PACKET,
SEND_PACKET_BROADCAST and HEADER_SIZE leave dCommonVars.h;
- the free BitStreamUtils::WriteHeader (LUBitStream::WriteHeader writes the
same bytes) and the unused PacketUtils::SavePacket are deleted.
The last raw reads are replaced: WorldServer builds its input stream
directly, the master packet logs read the header with
LUBitStream::ReadHeader instead of peeking at packet->data[1] and [3], and
MessageInspector reads a sent game message's header with the new
NetGameMsg::ReadPacketHeader (the counterpart of WritePacket) instead of
memcmp/memcpy. packet->data[0] is still compared with RakNet's own
connection IDs.
The frozen oracles keep using the macros verbatim through the test-only
tests/dGameTests/LegacyPacketMacros.h; the HeaderSkip tests, which only
tested CINSTREAM_SKIP_HEADER, are removed.
docs/PacketArchitecture.md: "where we are" now describes the final state
and what still touches raw bytes (RakNet IDs, replica headers, behavior bit
streams), and a new section collects the known wire discrepancies found
during the conversion, with client addresses.

Converts build mode, arranging, modular build and brick by brick
messages to NetGameMsgs in BuildingMessages.{h,cpp}: StartArrangingWithItem,
FinishArrangingWithItem, ModularBuildEnd and SetBuildModeConfirmed
(sent), and StartBuildingWithItem, DoneArrangingWithItem,
ModularBuildFinish, ModularBuildMoveAndEquip, ModularBuildConvertModel,
SetBuildMode, BuildModeSet, UnUseBBBModel, BBBLoadItemRequest and
BBBSaveRequest (received, registered in GameMessageHandler's map with
their handlers' logic kept). The BLUEPRINT_SAVE_RESPONSE and
BLUEPRINT_LOAD_RESPONSE_ITEMID client packets become the LUBitStream
structs ClientPackets::BlueprintSaveResponse and BlueprintLoadItemResponse,
also used by WorldServer's level load. The never-called
SendBBBSaveResponse is gone.
SetBuildModeConfirmed keeps writing modeValue's and startPos's default
flags as always set, as DLU did. BuildModeSet and UnUseBBBModel now read
their whole client layout (DLU read only the first fields).
No wire change and no change in recipients. Verified byte for byte
against a frozen verbatim copy of the old functions and inline packet
writes over an input grid, received messages compared with the old
handlers' read sequences with every truncated payload rejected, hand
computed golden bytes, round trips and a mutation check. Layouts
confirmed against the 1.10.64 client in Ghidra.
