Kevin Wolf 69dd62dfd6 qapi: Anonymous unions
The discriminator for anonymous unions is the data type. This allows to
have a union type that allows both of these:

    { 'file': 'my_existing_block_device_id' }
    { 'file': { 'filename': '/tmp/mydisk.qcow2', 'read-only': true } }

Unions like this are specified in the schema with an empty dict as
discriminator. For this example you could take:

    { 'union': 'BlockRef',
      'discriminator': {},
      'data': { 'definition': 'BlockOptions',
                'reference': 'str' } }
    { 'type': 'ExampleObject',
      'data: { 'file': 'BlockRef' } }

Kevin Wolf 50f2bdc75c qapi: Flat unions with arbitrary discriminator
Instead of the rather verbose syntax that distinguishes base and
subclass fields...

  { "type": "file",
    "read-only": true,
    "data": {
        "filename": "test"
    } }

...we can now have both in the same namespace, allowing a more direct
mapping of the command line, and moving fields between the common base
and subclasses without breaking the API:

  { "driver": "file",
    "read-only": true,
    "filename": "test" }

Michael R. Hines a5f56b906e rdma: update documentation to reflect new unpin support
As requested, the protocol now includes memory unpinning support.
This has been implemented in a non-optimized manner, in such a way
that one could devise an LRU or other workload-specific information
on top of the basic mechanism to influence the way unpinning happens
during runtime.

The feature is not yet user-facing, and is thus can only be enabled
at compile-time.

TARGET_ARCH is generally wrong to use, there are better variables
provided in config-target.mak.  The right one is usually TARGET_NAME
(previously TARGET_ARCH2), but for bsd-user we can also use TARGET_ABI_DIR

Paolo Bonzini 1964a39706 migration: move rate limiting to QEMUFile
Rate limiting is now simply a byte counter; client call
qemu_file_rate_limit() manually to determine if they have to exit.
So it is possible and simple to move the functionality to QEMUFile.

This makes the remaining functionality of s->file redundant;
in the next patch we can remove it and write directly to s->migration_file.

Gerd Hoffmann df9ffb726f vga: fix bochs alignment issue
The bochs dispi interface traditionally uses port 0x1ce as 16bit index
register and port 0x1cf as 16bit data register.  The later is unaligned,
and probably for that reason the the data register was moved to 0x1d0
for non-x86 archs.

This patch makes the data register available at 0x1d0 on x86 too.  The
old x86 location is kept for compatibility reasons, so both 0x1cf and
0x1d0 can be used as data register on x86.

The dirty bit will make it possible to perform lazy refcount updates,
where the image file is not kept consistent all the time.  Upon opening
a dirty image file, it is necessary to perform a consistency check and

Therefore the dirty bit must be an incompatible feature bit.  We don't

- allow visitors to set a NULL struct pointer successfully, so traversal
  of incomplete objects can continue
- check for a NULL "obj" before accessing "(*obj)->has_XXX" (this is not a
  typo, "obj != NULL" implies "*obj != NULL" here)
- fix start_struct / end_struct balance for unions as well
