Changes: - Save CPU cycles by computing the return value while scanning the input iovec, rather than calling iov_size() at the end. - Remove check for s->tx != NULL, because it cannot happen. - Cache ring->tail in a local variable and use it to check for space in the TX ring. The use of nm_ring_empty() was invalid, because nobody is updating ring->cur and ring->head at that point. - In case we run out of netmap slots in the middle of a packet, move the wake-up point by advancing ring->cur, but do not expose the incomplete packet (i.e., by updating also ring->head).

This change improves the handling of incomplete multi-slot packets (e.g. with the NS_MOREFRAG set), by advancing ring->head only on complete packets. The ring->cur pointer is advanced in any case in order to acknowledge the kernel and move the wake-up point (thus avoiding repeated wake-ups). Also don't be verbose when incomplete packets are found.

The OSX Mojave release is more picky about enforcing the Cocoa API restriction that only the main thread may perform UI calls. To accommodate this we need to restructure the Cocoa code: * the special OSX main() creates a second thread and uses that to call the vl.c qemu_main(); the original main thread goes into the OSX event loop * the refresh, switch and update callbacks asynchronously tell the main thread to do the necessary work * the refresh callback no longer does the "get events from the UI event queue and handle them" loop, since we now use the stock OSX event loop. Instead our NSApplication sendEvent method will either deal with them or pass them on to OSX All these things have to be changed in one commit, to avoid breaking bisection. Note that since we use dispatch_get_main_queue(), this bumps our minimum version requirement to OSX 10.10 Yosemite (released in 2014, unsupported by Apple since 2017).

When we switch away from our custom event handling, we still want to be able to have first go at any events our application receives, because in full-screen mode we want to send key events to the guest, even if they would be menu item activation events. There are several ways we could do that, but one simple approach is to subclass NSApplication so we can implement a custom sendEvent method. Do that, but for the moment have our sendEvent just invoke the superclass method.

Currently the switchSurface method takes a DisplaySurface. We want to change our DisplayChangeListener's dpy_gfx_switch callback to do this work asynchronously on a different thread. The caller of the switch callback will free the old DisplaySurface immediately the callback returns, so to ensure that the other thread doesn't access freed data we need to switch to using the underlying pixman image instead. The pixman image is reference counted, so we will be able to take a reference to it to avoid it vanishing too early. In this commit we only change the switchSurface method to take a pixman image, and keep the flow of control synchronous for now.

The floating-point extension facility implemented certain changes to BFP, HFP and DFP instructions. As we don't implement HFP/DFP, we can ignore those completely. Related to BFP, the changes include - SET BFP ROUNDING MODE (SRNMB) instruction - BFP-rounding-mode field in the FPC register is changed to 3 bits - CONVERT FROM LOGICAL instructions - CONVERT TO LOGICAL instructions - Changes (rounding mode + XxC) added to -- CONVERT TO FIXED -- CONVERT FROM FIXED -- LOAD FP INTEGER -- LOAD ROUNDED -- DIVIDE TO INTEGER For TCG, we don't implement DIVIDE TO INTEGER, and it is harder to implement, so skip that. Also, as we don't implement PFPO, we can skip changes to that as well. The other parts are now implemented, we can indicate the facility. z14 PoP mentions that "The floating-point extension facility is installed in the z/Architecture architectural mode. When bit 37 is one, bit 42 is also one.", meaning that the DFP (decimal-floating-point) facility also has to be indicated. We can ignore that for now.
