Revert "Win32: fix #2592 (stdin file input). It may impact other platforms, so please test, and fix/revert if you see a bug."

This reverts commit e33a82db.
This broke opening any file starting with a dash.

This enables passing a below state in addition to currently supported
always-on-top (above) and normal. (However, none of the window provider
support it just yet).

Should fix aspect-ratio issues and fixes #2793

Win32: fix #2592 (stdin file input). It may impact other platforms, so please test, and fix/revert if you see a bug.

configure: Make sure independant Mac OS X-related modules can be activated/deactivated individually.

Else, this results in triggering the timeshift module.

Modified the main OS X interface module to remove the use of setjmp() and longjmp(). The MainMenu.nib file was modified to invoke the stop selector instead of the terminate selector on the NSApp object. This allows the OS X framework to return from the call [NSApp run] instead of using setjmp()/longjmp() in a managed framework.

Currently only used to display the question, login, error and critical core dialogs whenever VLC runs with a GUI on a Mac.

Disabled by default. The login dialog's layout will need some more love.

Use the generic singleton for Bookmarks, ErrorsDialog, extended dialog, GotoTime dialog, every help class, MediaInfo, Messages, OpenURL, Playlist, Plugin, Podcast configuration and VLM. Also fix some memleaks when quitting
