Gcc 4.5.* build fix.

Q_COMPILER_DEFAULT_MEMBERS and Q_COMPILER_DELETE_MEMBERS are now set
starting from gcc 4.6. Pre-4.6 compilers implement a non-final snapshot
of N2346, hence default and delete functions are supported only if they
are public. Starting from 4.6, GCC handles final version - the access
modifier is not relevant. Compiler error:

  qsharedpointer_impl.h:717:31: error:
  'QEnableSharedFromThis<T>::QEnableSharedFromThis()' declared with non-public access cannot be defaulted in the class body

Android: Return empty mime data instead of 0 from empty clipboard

This is consistent with other platforms such as iOS and
XCB, which return a QMimeData with an empty text when the clipboard
is empty.

[ChangeLog][Android] QClipboard::mimeData() now returns an empty
object instead of null pointer from QClipboard when clipboard is
empty for consistency with other platforms.

Fix memory leak in QClipboard::setMimeData()

The setMimeData() function is documented to take ownership of
the object passed in, but in the case where the platform
plugin did not support the requested mode, we would simply
return without deleting the object nor telling the application,
so it would cause a potential memory leak. We need to honor the
contract, even when we fail to set the mime data.

Test was updated to avoid verifying the leak in cases where
the platform does not support all modes.

[ChangeLog][QtGui][Clipboard] Fixed a memory leak in setMimeData()
when the platform plugin did not support the requested mode.

Android: Make memory handling in QClipboard consistent with iOS

On iOS we do deleteLater() on the mime data instead of deleting
it directly, in case the application should happen to use the
pointer again directly after setting it on the clipboard.
Technically it would be a bug in the application, but using
deleteLater() is safer and it's better to be consistent with
iOS so that a buggy application crashes in the same places in
both.
