Rewrite client media download and support hash-based remote download Move most of the media-related code in client.cpp into a new class ClientMediaDownloader (clientmedia.cpp, clientmedia.h). Among other things, this class does the following things: - Download [remote_server][sha1] instead of [remote_server][name]. This is to support servers that provide the same file name with different contents. - Initially fetch [remote_server]index.mth. This file should follow the Minetest Hashset format (currently version 1) and contain a list of SHA1 hashes that exist on the server. - The list of needed SHA1s is uploaded (via HTTP POST) when index.mth is requested, so servers can optionally narrow down the list to the needs of the client. - If index.mth is missing (HTTP response code 404), we enter compat mode, fetching [remote_server][name] as before this commit. - remote_server can now contain multiple servers, separated by commas. The downloader code attempts to split requests between the different servers, as permitted by each server's index.mth. If one server claims to have a file but actually doesn't (or something fails), we ask a different server that also claims to have it. - As before, when none of the remote servers provide a particular file, we download it via the conventional method, i.e. using the minetest protocol: TOSERVER_REQUEST_MEDIA / TOCLIENT_MEDIA. - Bugfix: Every downloaded file's SHA1 is now verified against the SHA1 announced by the minetest server (before loading it and inserting it into the file cache). - Bugfix: Only send TOSERVER_RECEIVED_MEDIA when we actually have all media. This should fix #863.

[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

Rewrite client media download and support hash-based remote download Move most of the media-related code in client.cpp into a new class ClientMediaDownloader (clientmedia.cpp, clientmedia.h). Among other things, this class does the following things: - Download [remote_server][sha1] instead of [remote_server][name]. This is to support servers that provide the same file name with different contents. - Initially fetch [remote_server]index.mth. This file should follow the Minetest Hashset format (currently version 1) and contain a list of SHA1 hashes that exist on the server. - The list of needed SHA1s is uploaded (via HTTP POST) when index.mth is requested, so servers can optionally narrow down the list to the needs of the client. - If index.mth is missing (HTTP response code 404), we enter compat mode, fetching [remote_server][name] as before this commit. - remote_server can now contain multiple servers, separated by commas. The downloader code attempts to split requests between the different servers, as permitted by each server's index.mth. If one server claims to have a file but actually doesn't (or something fails), we ask a different server that also claims to have it. - As before, when none of the remote servers provide a particular file, we download it via the conventional method, i.e. using the minetest protocol: TOSERVER_REQUEST_MEDIA / TOCLIENT_MEDIA. - Bugfix: Every downloaded file's SHA1 is now verified against the SHA1 announced by the minetest server (before loading it and inserting it into the file cache). - Bugfix: Only send TOSERVER_RECEIVED_MEDIA when we actually have all media. This should fix #863.
