Denis V. Lunev 19f5dc1591 block/parallels: optimize linear image expansion
Plain image expansion spends a lot of time to update image file size.
This seriously affects the performance. The following simple test
  qemu_img create -f parallels -o cluster_size=64k ./1.hds 64G
  qemu_io -n -c "write -P 0x11 0 1024M" ./1.hds
could be improved if the format driver will pre-allocate some space
in the image file with a reasonable chunk.

This patch preallocates 128 Mb using bdrv_write_zeroes, which should
normally use fallocate() call inside. Fallback to older truncate()
could be used as a fallback using image open options thanks to the
previous patch.

The benefit is around 15%.

Denis V. Lunev d61790112f block/parallels: add prealloc-mode and prealloc-size open paramemets
This is preparational commit for tweaks in Parallels image expansion.
The idea is that enlarge via truncate by one data block is slow. It
would be much better to use fallocate via bdrv_write_zeroes and
expand by some significant amount at once.

Original idea with sequential file writing to the end of the file without
fallocate/truncate would be slower than this approach if the image is
expanded with several operations:
- each image expanding means file metadata update, i.e. filesystem
  journal write. Truncate/write to newly truncated space update file
  metadata twice thus truncate removal helps. With fallocate call
  inside bdrv_write_zeroes file metadata is updated only once and
  this should happen infrequently thus this approach is the best one
  for the image expansion
- tail writes are ordered, i.e. the guest IO queue could not be sent
  immediately to the host introducing additional IO delays

This patch just adds proper parameters into BDRVParallelsState and
performs options parsing in parallels_open.

Denis V. Lunev 0d31c7c200 block/parallels: delay writing to BAT till bdrv_co_flush_to_os
The idea is that we do not need to immediately sync BAT to the image as
from the guest point of view there is a possibility that IO is lost
even in the physical controller until flush command was finished.
bdrv_co_flush_to_os is exactly the right place for this purpose.

Technically the patch uses loaded BAT data as a cache and performs
actual on-disk metadata updates in parallels_co_flush_to_os callback.

This patch speed ups
  qemu-img create -f parallels -o cluster_size=64k ./1.hds 64G
  qemu-io -f parallels -c "write -P 0x11 0 1024k" 1.hds
writing from 50-60 Mb/sec to 80-90 Mb/sec on rotational media and
from 160 Mb/sec to 190 Mb/sec on SSD disk.

Denis V. Lunev 6dd6b9f144 block/parallels: implement incorrect close detection
The software driver must set inuse field in Parallels header to
0x746F6E59 when the image is opened in read-write mode. The presence of
this magic in the header on open forces image consistency check.

There is an unfortunate trick here. We can not check for inuse in
parallels_check as this will happen too late. It is possible to do
that for simple check, but during the fix this would always report
an error as the image was opened in BDRV_O_RDWR mode. Thus we save
the flag in BDRVParallelsState for this.

On the other hand, nothing should be done to clear inuse in
parallels_check. Generic close will do the job right.

...which is techinically true, but the real error is that we failed to
unlink. So report it.

This may seem pathological but it's a real possibility via libvirt.

Cole Robinson bc119048d7 vnc: Tweak error when init fails
Before:
qemu-system-x86_64: -display vnc=unix:/root/foo.sock: Failed to start VNC server on `(null)': Failed to bind socket to /root/foo.sock: Permission denied

After:
qemu-system-x86_64: -display vnc=unix:/root/foo.sock: Failed to start VNC server: Failed to bind socket to /root/foo.sock: Permission denied

Rather than tweak the string possibly show unix: value as well,
just drop the explicit display reporting. We already get the cli
string in the error message, that should be sufficient.

Gerd Hoffmann a48da7b5bc serial: fix multi-pci card error cleanup.
Put the number of serial ports into a local variable in
multi_serial_pci_realize, then increment the port count
(pci->ports) as we initialize the serial port cores.

Now pci->ports always holds the number of successfully
initialized ports and we can use multi_serial_pci_exit
to properly cleanup the already initialized bits in case
of a init failure.

Peter Maydell 8617989eae ui/cocoa: Avoid deprecated NSOKButton/NSCancelButton constants
In OSX 10.10, the NSOKButton and NSCancelButton constants are deprecated
and provoke compiler warnings. Avoid them by using the
NSFileHandlingPanelCancelButton and NSFileHandlingPanelOKButton constants
instead. These are the documented correct constants for the 10.6-and-up
beginSheetModalForWindow API we use. We also use the same method for
the pre-10.6 compatibility code path, but conveniently the constant
values are the same and the constant names have been present since 10.0.
Preferring the constant names that match the non-legacy API makes more
sense anyway.

Peter Maydell 2a4c8c53da ui/cocoa: Declare that QemuCocoaAppController implements NSApplicationDelegate
Our class QemuCocoaAppController implements the NSApplicationDelegate
interface, and we pass an object of this class to [NSApp setDelegate].
However, we weren't declaring in the class definition that we implemented
this interface; in OSX 10.10 this provokes the following (slighly
misleading) warning:
ui/cocoa.m:1031:24: warning: sending 'QemuCocoaAppController *' to parameter of
      incompatible type 'id<NSFileManagerDelegate>'
    [NSApp setDelegate:appController];
                       ^~~~~~~~~~~~~
/System/Library/Frameworks/Foundation.framework/Headers/NSFileManager.h:109:47:
note: passing argument to parameter 'delegate' here
@property (assign) id <NSFileManagerDelegate> delegate NS_AVAILABLE(10_5,
2_0);
                                              ^

Annoyingly, this interface wasn't formally defined until OSX 10.6, so we
have to surround the relevant part of the @interface line with an ifdef.

Peter Maydell b63901d84c ui/cocoa: Drop tests for CGImageCreateWithImageInRect support
The code that tries to test at both compiletime and runtime
for whether CGImageCreateWithImageInRect is supported provokes
a compile warning on OSX 10.3:

ui/cocoa.m:378:13: warning: comparison of function 'CGImageCreateWithImageInRect'
      equal to a null pointer is always false[-Wtautological-pointer-compare]
        if (CGImageCreateWithImageInRect == NULL) { // test if "CGImageCreateWithImageInRect" is
supported on host at runtime
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~    ~~~~

The simplest way to deal with this is just to drop this code,
since we don't in practice support OSX 10.4 anyway. (10.5 was
released in 2007 and is the last PPC version, so is the earliest
we really need to continue to support at all.)
