These commands use prepare_command() to find a channel to act on, which returns the server to use.
The code should then use my_send_to_server() to ensure that it sends the command to that server -
these functions were using send_to_server() which sends to 'from_server', which means that they
could send the commands to the wrong place, for example if they were called from a hook on a
different server.
This patch was created with the following coccinelle script:
// Detects pairing preprare_command() with send_to_server() (which uses from_server)
@prepare3@
identifier s;
local idexpression c;
expression E1, E2, E3, E4, E5;
