Consistent logging in Environment and PropertySource implementations [SPR-15825]

[spring-projects-issues]

Juergen Hoeller opened SPR-15825 and commented

Classes like AbstractEnvironment and MutablePropertySources historically accumulated quite a bit of logging (implemented in log messages as well as toString() implementations) which turns out to be slightly inconsistent in its formatting of property source names. This is easy enough to overhaul, so let's do this not only for 5.0 but also for 4.3.11.
