370a03f0a3 refactor: remove the packet macros, WriteHeader and PacketUtils
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.

e9ab4f5418 refactor: vendor, donation and trade game messages as structs
Converts the vendor, donation vendor and trade game messages to
NetGameMsgs in VendorMessages.{h,cpp} and TradeMessages.{h,cpp}:
VendorOpenWindow and VendorTransactionResult (SendToClient: the old
functions never broadcast), VendorStatusUpdate, ServerTradeInvite,
ServerTradeInitialReply, ServerTradeFinalReply, ServerTradeAccept,
ServerTradeCancel and ServerTradeUpdate, and the received
RequestVendorStatusUpdate, BuyFromVendor, SellToVendor,
BuybackFromVendor, AddDonationItem, RemoveDonationItem,
ConfirmDonationOnPlayer, CancelDonationOnPlayer, ClientTradeRequest,
ClientTradeCancel, ClientTradeAccept and ClientTradeUpdate. A trade
offer entry (the client's inventory item layout, optional fields and
config block included) is TradeItemEntry, shared by both trade updates.

Selling and buying back move into VendorComponent (SellToVendor,
BuybackFromVendor), adding and confirming donations into
DonationVendorComponent, and VendorComponent builds its own status
update and transaction results. Only the VENDOR component sends its
stock, as before. The received messages are registered in
GameMessageHandler's map, the switch cases and the old functions are
deleted. Handler logic is unchanged.

No wire change and no change in recipients. Verified byte for byte
against a frozen verbatim copy of the old functions over an input grid
(to one client and broadcast), received messages compared with the old
handlers' read sequences (every optional field of a trade entry,
raw and compressed config blocks) and truncated payloads rejected, hand
computed golden bytes, round trips, and a deliberate width mutation made
the tests fail. ConfirmDonationOnPlayer still accepts a message without
its vendor ID, since the old handler read nothing.
