76dc75ca54 build: rename CONFIG_QGA_NTDDDISK to CONFIG_QGA_NTDDSCSI
There was inconsistency between commits:

  50cbebb9a3 configure: add configure check for ntdddisk.h
  a3ef3b2272 qga: added bus type and disk location path

The first commit added #define CONFIG_QGA_NTDDDISK but the second commit
expected the name to be CONFIG_QGA_NTDDSCSI. As a result the code in
second patch was never used.

Renaming the option to CONFIG_QGA_NTDDSCSI to match the name of header
file that is being checked for.

6880b94f8a qga-win: fsinfo: pci-info: allow partial info
The call to SetupDiGetDeviceRegistryProperty might fail because the
value doesn't exist in the registry, in this case we shouldn't exit from
the loop but instead continue to look for other available values in the
registry and set this value as unavailable (-1).

0d7f937e2a qga-win: prevent crash when executing fsinfo command
The fsinfo command is currently implemented for Windows only and it's disk
parameter can be enabled by adding the define "CONFIG_QGA_NTDDSCSI" to the qga
code. When enabled and executed the qemu-ga crashed with the following message:

------------------------------------------------
File qapi/qapi-visit-core.c, Line 49

Expression: !(v->type & VISITOR_OUTPUT) || *obj)
------------------------------------------------

After some digging, turns out that the GuestPCIAddress is null and the
qapi visitor doesn't like that, so we can always allocate it instead and
initiate all it's members to -1.

bad0227d3a qga: Support Unicode paths in guest-file-open on win32
Currently, the win32 port of QEMU Guest Agent does not properly handle Unicode
paths. The JSON decoder produces a valid UTF-8 path string, but this is passed
directly to CreateFileA, which is expecting an ANSI string and not UTF-8. This
leads to mangled filenames.

This patch follows the example of qmp_guest_set_user_password() and uses
g_utf8_to_utf16() to convert the string to UTF-16 and calls CreateFileW()
explicitly.

b9247fc1a8 iotests: improve 169
Before previous patch, iotest 169 was actually broken for the case
test_persistent__not_migbitmap__offline_shared, while formally
passing.

After migration log of vm_b had message:

    qemu-system-x86_64: Could not reopen qcow2 layer: Bitmap already
    exists: bitmap0

which means that invalidation failed and bs->drv = NULL.

It was because we've loaded bitmap twice: on open and on invalidation.

Add code to 169, to catch such fails.

9c98f145df dirty-bitmaps: clean-up bitmaps loading and migration logic
This patch aims to bring the following behavior:

1. We don't load bitmaps, when started in inactive mode. It's the case
of incoming migration. In this case we wait for bitmaps migration
through migration channel (if 'dirty-bitmaps' capability is enabled) or
for invalidation (to load bitmaps from the image).

2. We don't remove persistent bitmaps on inactivation. Instead, we only
remove bitmaps after storing. This is the only way to restore bitmaps,
if we decided to resume source after [failed] migration with
'dirty-bitmaps' capability enabled (which means, that bitmaps were not
stored).

3. We load bitmaps on open and any invalidation, it's ok for all cases:
  - normal open
  - migration target invalidation with dirty-bitmaps capability
    (bitmaps are migrating through migration channel, the are not
     stored, so they should have IN_USE flag set and will be skipped
     when loading. However, it would fail if bitmaps are read-only[1])
  - migration target invalidation without dirty-bitmaps capability
    (normal load of the bitmaps, if migrated with shared storage)
  - source invalidation with dirty-bitmaps capability
    (skip because IN_USE)
  - source invalidation without dirty-bitmaps capability
    (bitmaps were dropped, reload them)

[1]: to accurately handle this, migration of read-only bitmaps is
     explicitly forbidden in this patch.

New mechanism for not storing bitmaps when migrate with dirty-bitmaps
capability is introduced: migration filed in BdrvDirtyBitmap.

d1dde7149e bitmap: Update count after a merge
We need an accurate count of the number of bits set in a bitmap
after a merge. In particular, since the merge operation short-circuits
a merge from an empty source, if you have bitmaps A, B, and C where
B started empty, then merge C into B, and B into A, an inaccurate
count meant that A did not get the contents of C.

In the worst case, we may falsely regard the bitmap as empty when
it has had new writes merged into it.

993edc0ce0 block/dirty-bitmaps: add user_locked status checker
Instead of both frozen and qmp_locked checks, wrap it into one check.
frozen implies the bitmap is split in two (for backup), and shouldn't
be modified. qmp_locked implies it's being used by another operation,
like being exported over NBD. In both cases it means we shouldn't allow
the user to modify it in any meaningful way.

Replace any usages where we check both frozen and qmp_locked with the
new check.

9c956e6461 spice: prepare for upcoming spice-server change
Future spice-server versions will call the client_monitors_config
callback with the monitors list filtered to only include the monitors
of the given display channel (aka QXLInstance).  Luckily this is easily
detectable at runtime, so we can prepare for that in advance and also
make qemu compatible with both old and new spice-server versions.

While being at it also use the console index instead of head number as
array index.  The later doesn't work correctly in case multiple display
devices are present.
