When 'log' directive was implemented, the internal representation was named 'struct logsrv', because the 'log' directive would directly point to the log target, which used to be a (UDP) log server exclusively at that time, hence the name. But things have become more complex, since today 'log' directive can point to ring targets (implicit, or named) for example. Indeed, a 'log' directive does no longer reference the "final" server to which the log will be sent, but instead it describes which log API and parameters to use for transporting the log messages to the proper log destination. So now the term 'logsrv' is rather confusing and prevents us from introducing a new level of abstraction because they would be mixed with logsrv. So in order to better designate this 'log' directive, and make it more generic, we chose the word 'logger' which now replaces logsrv everywhere it was used in the code (including related comments). This is internal rewording, so no functional change should be expected on user-side.
