Bump logback to 1.2.3 and SLF4J to 1.7.25

The changelog entries that stand out the most:

* The ReentrantLock in OutputStreamAppender is now "unfair". In previous
  versions of logback, a fair lock was used. Fair locks are much slower.
  Just as importanly, logback has no mandate to influence thread scheduling.
* In PatternLayoutBase the same StringBuilder is used over and over to
  reduce memory allocation.

I am unable to observe any improvements in our micro-benchmarks. In any
case, I still think it is worth to stay up to date.

Full changelogs:
