Summary:
When running okular with the parameter --print to directly open the print mode, it doesn't exit after acknowledging the print dialog. Hence adding --print_and_exit option exits Okular after acknowledging the print dialog and thus is useful for the command line batch processing or a Dolphin service as the issue suggests.
FEATURE: 318998
Test Plan:
1. open a file in Okular using the parameter --print. It will open Okular in print mode with the print dialog
2. Either print the file or cancel the print dialog
3. You will find that Okular stays open
4. Now using this patch, see for available options with the --help parameter. You will find --print_and_exit option
5. Now open a file in Okular using the parameter --print_and_exit. It will open Okular in print mode with the print dialog
6. Either print the file or cancel the print dialog
7. You will find that Okular closes after acknowledging the dialog

Differential Revision: https://phabricator.kde.org/D10249
by removing much cruft and using the shiny new QUrl::fromUserInput(2 args),
but since that requires Qt 5.4, also include a copy here if Qt is too "old".

Use a QString to serialize the command line options other than urls to open so it can be easily passed around to every place that opens a new shell or tab or overrides the content in a unique instance.

make the function able to be reused in unit tests (ie adding a function hook for the filename existance check)
