Background:

The Router logger was very basic and always emitted started and completed logs which were of limited utility. It was difficult from the router log alone to determine which routing function was responsible for creating the response seen.

Further the routing involved reflection at runtime to determine where to route to - this is inefficient and slow, and there was a bug in that the logging level was not previously logged.

This PR

  • Started logging is now at Trace level
  • Long polling handlers are recognised and slow executing routes are logged.
  • All logging lines (except started) state the name of the function that is currently running.
  • This PR prewraps the router functions meaning that reflection no longer occurs a routing time, as all reflection is precalculated.

⚠️ BREAKING ⚠️

This PR substantially changes the logging format of the router logger. If you use this logging for monitoring e.g. fail2ban you will need to update this to match the new format.

I don't completely understand what you're trying to do here but I really dislike the "panic occurred " changes.

I've sent a small PR to do a few changes but I'll need to think a bit more about this.

Remove logger v1
4cb7e03 
Now 1.16.0 is out and we're at the start of the v1.17 cycle we can make
more radical breaking changes. In which case we can simply remove the
logger v1 changes.

Although this is potentially an extremely breaking change - we are making this change right at the start of the 1.17 cycle therefore we have time for people to spot this and complain.

If necessary we can implement the changes in wxiaoguang#4 and rediscuss the log levels for started etc.
