The old code model expected the macros as C++ formatted text
("#define Foo 42) but newer targets like the Clang codemodel expect key
value arguments like "-DFoo=42". So instead of parsing the text again and
again we use an abstract data description.

Utils::matchCaseReplacement searches for common prefix and suffix
between old and new file name und leaves them unchanged. This leads
to unexpected new file names.

E.g. when renaming MainWindow to MyMainWindow, this function computes
the prefix "m", the suffix "ainwindow.h" and only considers "yM" as
the middle part that is actually renamed.

Use a better algorithm to determine the new base name, and for
unclear cases fall back to the "Lower case file names" option
from Tools -> Options -> C++ -> File Naming.

- fix memory leak in find-usages
- do not retain snapshot in search history
- when an editor is invisible for more than 2 minutes, release the

Retaining snapshots will retain their documents, and if done for too
long, the memory consumption might grow. This is especially the case
when switching to a different kit (Qt version): in that case, the new
versions of headers will be indexed, while the old ones stay around.
