This helps us construct strings elsewhere before echoing to the
monitor. It avoids having to jump through hoops like:
monitor_printf(mon, "%s", s->str);
It will be useful in following patches but for now convert all
existing plain "%s" printfs to use the _puts api.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).

We don't want it to be possible to re-read the RNG seed after ingesting
it, because this ruins forward secrecy. Currently, however, the setup
data section can just be re-read. Since the kernel is always read after
the setup data, use the selection of the kernel as a trigger to
re-initialize the RNG seed, just like we do on reboot, to preserve
forward secrecy.

CHS-based disk utilities and operating systems may adjust the logical
geometry of a hard drive to cope with the expectations or limitations
of software using the ATA INITIALIZE_DEVICE_PARAMETERS command.

corruption if the CHS<->LBA translation redirected a write to the
wrong sector.

Prior to this patch, cmd_exec_dev_diagnostic relied upon
ide_set_signature to clear the device register. While the
preservation of the drive bit by ide_set_signature is necessary for
the DEVICE RESET, IDENTIFY DEVICE, and READ SECTOR commands,
ATA/ATAPI-6 specifies that "DEV shall be cleared to zero" for EXECUTE
DEVICE DIAGNOSTIC.
This deviation was uncovered by the ATACT Device Testing Program
written by Hale Landis.

Commit 5f76a7aac1 is looking harmless from
the first glance, but it has changed things a lot. 'libvirt' uses it to
detect that it should follow new initialization way and this changes
things considerably. With this procedure followed, blockdev_init() is
not called anymore and thus block_acct_setup() helper is not called.
This means in particular that defaults for block accounting statistics
are changed and account_invalid/account_failed are actually initialized
as false instead of true originally.
This commit changes things to match original world. There are the following
constraints:
* new default value in block_acct_init() is set to true
* block_acct_setup() inside blockdev_init() is called before
blkconf_apply_backend_options()
* thus newly created option in block device properties has precedence if
specified

The "msi-parent" property can be used on the PCI node when MSIs do not
contain sideband data (device IDs) [1]. In QEMU, MSI transactions
contain the requester ID, so the PCI node should use the "msi-map"
property instead of "msi-parent". In our case the property describes an
identity map between requester ID and sideband data.
This fixes a warning when passing the DTB generated by QEMU to dtc,
following a recent change to the GICv3 node:

As the close-on-exec flags is not set on the file descriptors returned
by socketpair() at default, the fds will survive across exec' function.
In the case that exec' function get invoked, such as the live-update feature
which is been developing, it will cause fd leaks.
To address this problem, we should call qemu_socketpair() to create an pair of
connected sockets with the close-on-exec flag set.

On error, vfio_get_iommu_info() frees and clears *info, but
vfio_connect_container() continues to use the pointer regardless
of the return value. Restructure the code such that a failure
of this function triggers an error and clean up the remainder of
the function, including updating an outdated comment that had
drifted from its relevant line of code and using host page size
for a default for better compatibility on non-4KB systems.

The structure VFIOMigration of a VFIODevice is allocated and initialized
in vfio_migration_init(). "device_state" and "vm_running" are initialized
to 0, indicating that VFIO device is_STOP and VM is not-running. The
initialization value is incorrect. According to the agreement, default
state of VFIO device is _RUNNING. And if a VFIO device is hot-plugged
while the VM is running, "vm_running" should be 1. This patch fixes it.

Since this is read from fw_cfg on each boot, the kernel zeroing it out
alone is insufficient to prevent it from being used twice. And indeed on
reboot we always want a new seed, not the old one. So re-fill it in this

If setup_data is being read into a specific memory location, then
generally the setup_data address parameter is read first, so that the
caller knows where to read it into. In that case, we should return
setup_data containing the absolute addresses that are hard coded and
determined a priori. This is the case when kernels are loaded by BIOS,
for example. In contrast, when setup_data is read as a file, then we
shouldn't modify setup_data, since the absolute address will be wrong by
definition. This is the case when OVMF loads the image.
This allows setup_data to be used like normal, without crashing when EFI
tries to use it.
(As a small development note, strangely, fw_cfg_add_file_callback() was
exported but fw_cfg_add_bytes_callback() wasn't, so this makes that
consistent.)

Commit 584acf34cb ("ati-vga: Fix reverse bit blts") introduced
the local dst_x and dst_y which adjust the (x, y) coordinates
depending on the direction in the SRCCOPY ROP3 operation, but
forgot to address the same issue for the PATCOPY, BLACKNESS and
WHITENESS operations, which also call pixman_fill().
Fix that now by using the adjusted coordinates in the pixman_fill
call, and update the related debug printf().
