tdf#47065 Add new file open UI options and implement a new thread

Add new UI options when opening a locked or non-writeable document
to allow the user to be notified when such a document becomes editable
.  If the user selects "Notify", then that document is added to a list
of open documents to be checked by a thread every 60 seconds for
read/write access and whether lock file is available/obtainable. If
access is allowed for a document, then show UI dialog to the user
asking to Reload that document.  If Reload is selected by the user
then that document is reloaded with read/write access.  The checking
thread is spawned only once no matter how many "Notify" documents
there are.  The thread is spawned if not already running when a new
"Notify" document is opened, and it terminates when all "Notify"
documents have been closed or the application terminates.

Also update badstatics clang plugin to ignore new global variables
introduced.
