kwin/src/netinfo.cpp
Vlad Zahorodnii 93e0265e4e Move source code to src/ directory 
Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.

This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.

We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.
