Remove unused functions reported by cppcheck (#10463)
Run unused functions reported by cppcheck

This change removes a few (but not all) unused functions.
Some unused helper functions were not removed due to their complexity and potential of future use.

c10952b574 Rework packet receiving in ServerThread
Notably it tries to receive all queued packets
between server steps, not just one.

ad7daf7b52 Add session_t typedef + remove unused functions (#6470)
* Add session_t typedef + remove unused functions

u16 peer_id is used everywhere, to be more consistent and permit some evolutions on this type in the future (i'm working on a PoC), uniformize u16 peer_id to SessionId peer_id

Of course, this is not ideal solution, but we want our users to be happy in the
first place, right?

7ddf67aa14 Chat protocol rewrite (#5117)
* New TOCLIENT_CHAT_MESSAGE packet

* Rename old packet to TOCLIENT_CHAT_MESSAGE_OLD for compat
* Handle TOCLIENT_CHAT_MESSAGE new structure client side
* Client chat queue should use a specific object
* SendChatMessage: use the right packet depending on protocol version (not complete yet)
* Add chatmessage(type) objects and handle them client side (partially)
* Use ChatMessage instead of std::wstring server side

* Update with timestamp support

82e35edff5 Make early protocol auth mechanism generic, and add SRP
Adds everything needed for SRP (and everything works too),
but still deactivated, as protocol v25 init packets aren't final yet.
Can be activated by changing the LATEST_PROTOCOL_VERSION header to 25
inside networkprotocol.h.

1fe4256462 Connection::Receive(): receive Network Packet instead of SharedBuffer<u8>.
Because we get a Buffer<u8> from ConnectionEvent, don't convert it to SharedBuffer<u8> and return it to Server/Client::Receive which will convert it to NetworkPacket
Instead, put the Buffer<u8> directly to NetworkPacket and return it to packet processing
This remove a long existing memory copy
Also check the packet size directly into Connection::Receive instead of packet processing

61f2d0ca34 Remove unused ConnectionCommand::sendToAll function. NetworkPacket::oldForgePacket returns Buffer instead of SharedBuffer and is used in ConnectionCommand instead of Connection::Send
This remove the NetworkPacket buffer => SharedBuffer => Buffer copy. Now NetworkPacket => Buffer

ed04e8e9e4 [Patch 2/4] Network rework: packet writing, sending and cleanups
NetworkPacket.cpp:
* Remove some deprecated functions, we must use streaming interface
* m_data converted from u8* to std::vector<u8>
* Add an exporter to forge packet to Connection object
* implement operator << std::wstring. n
* implement operator << std::string
* dynamic resize when write packet content.
* fix string writing and performances.
* create ServerCommandFactory, used by client to get useful informations about packet processing (sending).
  * Reliability
  * Transmit channel
* Implement putRawString for some ugly char (_INIT packet), and use it.
* Many packet read and write migrated
* Implement oldForgePacket to interface writing with current connection
* fix U8/char/bool writing
* fix string writing and performances.
* add some missing functions
* Use v3s16 read instead of reading x,y,z separately
* Add irr::video::SColor support into packets
* Add some missing handlers
* Add a template function to increase offset
* Throw a serialization error on packet reading (must be improved)

PacketFactories:
* Create ServerCommandFactory, used by client to get useful informations about packet processing (sending).
* Create ClientCommandFactory, used by server to get useful informations about packet processing (sending).

Client.cpp:
* implement NetworkPacket ::Send interface.
* Move packet handlers to a dedicated file
* Remove Client::Send(SharedBuffer)

Server.cpp:
* implement NetworkPacket ::Send interface.
* Rewrite all packets using NetworkPacket
* Move packet handlers to a dedicated file
* Remove Server::Send(SharedBuffer)

ClientIface.cpp:
* Remove sendToAll(SharedBuffer<u8>)

Connection.hpp rework:
* Remove duplicate include
* Remove duplicate negation
* Remove a useless variable
* Improve code performance by using a m_peers_list instead of scanning m_peers map
* Remove Connection::Send(SharedBuffer)
* Fix useafterfree into NetworkPacket Sending
* Remove unused Connection::sendToAll

Test.cpp:
* Remove dead code
* Update tests to use NetworkPackets

Misc:
* add new wrappers to Send packets in client, using NetworkPacket
* Add NetworkPacket methods for Connection
* coding style fix
* dead code since changes cleanup
* Use v3s16 read instead of reading x,y,z separately in some packets
* Use different files to handle packets received by client and server
* Cleanup: Remove useless includes

ok @Zeno-
Tested by @Zeno- @VanessaE and @nerzhul on running servers

a704c04f00 Network Layer 7 rework (Packet handling)
* Move networkcode to a dedicated directory
* Rename clientserver.h to network/networkprotocol.h (Better name) and sanitize some includes
* Create object NetworkPacket
  * It stores command (opcode) and data separated
  * It also stores peer_id
  * Data reading can be done by using a streaming interface
* Change packet routing analysis
  * Remove old conditional analysis
  * Now uses function pointed analysis and add connection state ({Client,Server}::handlers)
  * Connection state permit to categorize condition to handle before analyze packets
  * Create a handler for depreciated messages, instead of duplicating code
