[sr-dev] per module log level

[Daniel-Constantin Mierla]

Hello,

I just added a framework to enable per module log level. Following IRC 
devel meeting, I analyzed a bit and come up with a solution that relies 
on debugger module registering a callback to core for getting the log 
level per module. See my last commits related to debugger.

It still needs some enhancements to make it more flexible, maybe Hugh 
can jump in and contribute, I won't have time for it in the near future. 
Here is what I think will be nice to add:
- mi/rpc commands to change the log levels at runtime
- make log_level_mode accessible via cfg parameter reload framework so 
it can be enabled/disabled at runtime

Of course, enabling this feature will slow down a bit printing the log 
messages comparing with the case when this feature is disabled, but 
should be not that much, as modules log level are kept in memory in a 
hash table.

Cheers,
Daniel
