Backport of commit d5f6f40eb8b6a420520cb7c726959048593d2cab in
the frameworks repository of solid.

The signature change can be detected at runtime using Qt's QMetaObject
introspection mechanism. That prevents us from emitting the two
pesky warnings at runtime, polluting our konsoles.

Google is full of that warning, and there is also:

The locked overlay should be added also for directories, as there is no
distinct "unreadable directory" icon.
No overlay icon for "gzip files with .gz file ending", there is a
mimetype icon for gzip files.

parseURL() clean up the string from surrounding url("...") chars but also remove leading/trailing spaces that are legal in url attribute.
This patch is to remove surrounding space chars from url attribute before computing complete url.

Other browsers do the same and it helps debugging stuff.

If we're called out of bounds, sourceModel()->index() will take care of
returning an invalid model index anyway. So calling rowCount+columnCount
every time index() is called can be avoided. These calls can be particularly
slow when sitting on top of a stack of proxymodels. And index() itself is called
very often, i.e. when a proxymodel on top of us is used by a delegate
which calls data() for many different roles.

If href is null or empty completeURL return the document url and we end up
to request the document itself for a stylesheet or favicon.

The handling of the start directory in the KUrlRequester was only halfway implemented:
- m_startDir (the private field holding the start directory) is not initialised - the default value of startDir() is an empty URL instead of the current working dir.
- when the start dir changes, it is not always passed to the KUrlCompletion object of the lineedit. The suggestions showed when entering a relative path into the LineEdit might be wrong as a consequence.
- when selecting a file, the start directory does not change to the directory of the selected file - the API doc says it should.
- when the user entered a relative path into the LineEdit, url() returns a relative path instead of an absolute one.

Previously all images specified in a stylesheet were downloaded at parsing time, regardless.

some KDE apps become unresponsive. This seems to be caused by KDE's internal sockets created 
in /tmp which is normally on the same block device as the ongoing IO traffic. 

With this patch the sockets are created in the folder XDG_RUNTIME_DIR points to. On "current" 
systems this folder is mounted with the tmpfs file system. So the sockets aren't affected by 
high IO load anymore.

In frameworks QStandardPaths is used which does the same, so there is no need to port it.

this is achieved by using --srcdir on meinproc5 to define the path where
to look for the customization directory

note: builddir/customization is populated by the relevant install

Closing all file descriptors prematurely causes an Apple OS X library
to crash and KCrash to terminate without starting Dr Konqi. There is
also a temporary fix to avoid starting Dr K via kdeinit4 on Apple OS X,
which fails because kdeinit4 (on OSX) is listening on the wrong socket.
