When xfstest generic/035, we found the target file was deleted
if the rename return -EACESS.
In cifs_rename2, we unlink the positive target dentry if rename
failed with EACESS or EEXIST, even if the target dentry is positived
before rename. Then the existing file was deleted.
We should just delete the target file which created during the
rename.

The Qt5 conversion broke support for debug info links.
Restore the behaviour added by changeset
ab45d190fd ("kconfig: create links in info window").
The original approach was to pass a pointer for a data struct
via an <a href>. That doesn't sound a good idea, as, if something
gets wrong, the app could crash. So, instead, pass the name of
the symbol, and validate such symbol at the hyperlink handling
logic.

When the search dialog box finds symbols/menus that match
the search criteria, it presents all results at the window.
Clicking on a search result should make qconf to navigate
to the selected item. This works on singleMode and on
fullMode, but on splitMode, the navigation is broken.
This was partially caused by an incomplete Qt5 conversion
and by the followup patches that restored the original
behavior.
When qconf is on split mode, it has to update both the
config and the menu views. Right now, such logic is broken,
as it is not seeking using the right structures.
On qconf, the screen is split into 3 parts:
+------------+-------+
| | |
| Config | Menu |
| | |
+------------+-------+
| |
| ConfigInfo |
| |
+--------------------+
On singleMode and on fullMode, the menuView is hidden, and search
updates only the configList (which controls the ConfigView).
On SplitMode, the search logic should detect if the variable is a
leaf or not. If it is a leaf, it should be presented at the menuView,
and both configList and menuList should be updated. Otherwise, just
the configList should be updated.
