* re-add macOS Fullscreen support
re added Full Screen support for macOS. Also refactored window methods in Controller.mm and moved to their own category - ControllerWindowMethods.mm
This has currently only been tested on macOS Monterey, and should be good on earlier versions - but perhaps needs testing on earlier versions of macOS.
fixes#3231#3234
* fixes a number of UI issues in the macOS torrent creator window listed in: https://github.com/transmission/transmission/issues/1891
* also fixes positioning of the source field, the piece info textfield, and the piece info stepper
* also updates the tracker add/remove control to use the newer rounded trect style as in the rest of the UI
* refactor: prefer constexpr over enum for GUI_PAD values
* refactor: prefer constexpr over enum for PrefsDialog values
* refactor: prefer constexpr over enum for StatsDialog values
* refactor: use enum class for GtrUnicode types
* refactor: prefer constexpr over enum for BT peer msg codes
* refactor: use enum class for TrMakemetaResult
* refactor: prefer constexpr over enum for BT metadata message types
* refactor: use enum class for AwaitingBt
* refactor: use enum class for EncryptionPreference
* refactor: use enum class for TrFormat in rpcimpl
* refactor: prefer constexpr over enum for QApp intervals
* refactor: prefer constexpr over enum for tr_resume bitfields
* refactor: prefer constexpr over enum for Qt/TrFileModel bitfields
* refactor: remove obsolete TODO comment in announce-list
* Add support for creating torrents with a source flag
* Add the source flag functionality for Mac OSX
* Source flag should be a part of the info dictionary
* Address review comments
* Rename "sourceFlag" to "source" since "Flag" is usually reserved for booleans.
* Free the "source" pointer in tr_metainfoFree.
* Add information about transmission-create argument to its manpage.
* Replace all occurences of "sourceFlag" with "source" and use "Source tag" in UI
* Settle on just "Source" in UI
* The last usage of "flag" hopefully bites the dust! ;-)
* Add a missing free for the source in tr_metainfoFree
* Add a "source" field to the torrent-get RPC method
* uncrustify
* Test for torrents having different infohashes due to different source flags.
This is the whole point of this feature, so it makes sense to test it.
* case is important
* try to incorporate the macosx xml changes
