for the three supported auth mechanisms around srp
Add new opcodes TOCLIENT_ACCEPT_SUDO_MODE and TOCLIENT_DENY_SUDO_MODE
for sudo mode handling (auth mech generic way of changing password).
Add TOCLIENT_HELLO for presenting server to client after client
presentation
Add TOCLIENT_AUTH_ACCEPT to accept connection from client
Rename GENERIC_CMD_SET_ATTACHMENT to AO_CMD_ATTACH_TO
PROTOCOL_VERSION 26:
Add TileDef tileable_horizontal, tileable_vertical flags
PROTOCOL_VERSION 27:
backface_culling: backwards compatibility for playing with
newer client on pre-27 servers.
Add nodedef v3 - connected nodeboxes
PROTOCOL_VERSION 28:
CPT2_MESHOPTIONS
PROTOCOL_VERSION 29:
Server doesn't accept TOSERVER_BREATH anymore
serialization of TileAnimation params changed
TAT_SHEET_2D
Removed client-sided chat perdiction
PROTOCOL VERSION 30:
New ContentFeatures serialization version
Add node and tile color and palette
Fix plantlike visual_scale being applied squared and add compatibility
with pre-30 clients by sending sqrt(visual_scale)
PROTOCOL VERSION 31:
Add tile overlay
Stop sending TOSERVER_CLIENT_READY
PROTOCOL VERSION 32:
Add fading sounds
PROTOCOL VERSION 33:
Add TOCLIENT_UPDATE_PLAYER_LIST and send the player list to the client,

Rename TOCLIENT_CHAT_MESSAGE to TOCLIENT_CHAT_MESSAGE_OLD (0x30)
Add TOCLIENT_CHAT_MESSAGE (0x2F)
This chat message is a signalisation message containing various
informations:
* timestamp
* sender
* type (RAW, NORMAL, ANNOUNCE, SYSTEM)
* content
Add TOCLIENT_CSM_RESTRICTION_FLAGS to define which CSM features should be
limited
Add settable player collisionbox. Breaks compatibility with older
clients as a 1-node vertical offset has been removed from player's
position
Add settable player stepheight using existing object property.
Breaks compatibility with older clients.
PROTOCOL VERSION 36:
Backwards compatibility drop
Add 'can_zoom' to player object properties
Add glow to object properties
Change TileDef serialization format.
Add world-aligned tiles.
Mod channels
Raise ObjectProperties version to 3 for removing 'can_zoom' and adding
'zoom_fov'.
Nodebox version 5
Add disconnected nodeboxes
Add TOCLIENT_FORMSPEC_PREPEND
PROTOCOL VERSION 37:
Redo detached inventory sending
Add TOCLIENT_NODEMETA_CHANGED
New network float format
ContentFeatures version 13
Add full Euler rotations instead of just yaw
Add TOCLIENT_PLAYER_SPEED
PROTOCOL VERSION 38:
Incremental inventory sending mode
Unknown inventory serialization fields no longer throw an error
Mod-specific formspec version
Player FOV override API
"ephemeral" added to TOCLIENT_PLAY_SOUND
PROTOCOL VERSION 39:
Updated set_sky packet
Adds new sun, moon and stars packets
Minimap modes
