Use the editor's displayName for the window title.
Also there were missing change signal emissions in setDisplayName
implementations.
Moves the actual handling of the window title from Session to
EditorManager (so it now is also done for the hypothetical case of no
project explorer plugin).

We didn't watch the symbolic link itself before, only the final link
target. We are watching the symbolic link and the final link target now.
Ugly hack: We need to work around QTBUG-15522. The inotify and kqueue
based file system watcher engines (Linux + Mac) don't report changes to
symbolic links. The workaround is to use the polling engine *only for
the links themselves*. The only way to force the use of the polling
engine is by using the auto test hook in QFileSystemWatcher.

- command argument quoting changes
- environment expansion changes
- substitution of ${SOURCE,BUILD}DIR with %{{source,build}Dir}
- VariableManger syntax change ${} => %{}

do not inject SOURCEDIR and BUILDDIR into the environment of
build steps and run configurations any more.
instead, all custom executable paths, argument lists and working
directories now support the %{sourceDir} and %{buildDir} macros.
this approach is more elegant and more scalable.

get away from argument stringlists. instead, use native shell command
lines which support quoting/splitting, environment variable expansion
and redirections with well-understood semantics.

instead of being os-agnostic, interpret the os-native expansion style,
so it is consistent with proper (shell) command lines.

don't interpret quotes, as this function is meant for expanding isolated
filepaths, where nobody would expect quoting. instead, use the windows
style of simply not doing an expansion if a referenced variable is not
found, which should be good enough - it's rather unlikely that something
which happens to be an expansion of an existing variable is actually not
meant to be one.

The fixed size buttons were too big on Mac.

Since all the debuggers are implemented in the debuggerplugin, that's a
natural place to put the action.

Disable/Enable them correctly and give them the correct context.
