QProcess: Handle spurious socket notifications for stdout and stderr On Unix systems where the GUI event dispatcher uses a notification system for socket notifiers that is out of band compared to select(), it's possible for the QSocketNotifier to activate after the pipe has been read from. When that happened, the ioctl(2) call with FIONREAD might return 0 bytes available, which we interpreted to mean EOF. Instead of doing that, always try to read at least one byte and examine the returned byte count from read(2). If it returns 0, that's a real EOF; if it returns -1 EWOULDBLOCK, we simply ignore the situation. That's the case on OS X: the Cocoa event dispatcher uses CFSocket to get notifications and those use kevent (and, apparently, an auxiliary thread) instead of an in-thread select() or poll(). That means the event loop would activate the QSocketNotifier even though there is nothing to be read.

Add cmdline feature to qmake [ChangeLog][qmake] A new feature "cmdline" was added that implies "CONFIG += console" and "CONFIG -= app_bundle".
