Up from the new PCM protocol 2.0.14, user-space can inform the
protocol version it supports to kernel, so that the kernel may switch
its behavior depending on it. Add this ioctl call in the PCM hw
plugin at opening.
The patch contains also the addition of SNDRV_PCM_INFO_SYNC_APPLPTR
carried from the upstream kernel commit 42f945970af9 ("ALSA: pcm: Add
the explicit appl_ptr sync support"), as well as the trivial change
(an addition of comma) to sync with the kernel asound.h.

This patch update physicals DAI link config to ABI v5:
- Define the types and ABI struct for runtime supported hardware configs
e.g. audio hardware formats. The default HW config ID will help topology
to find the DAI format to set on init. Topology provides this as a
fallback if such HW settings are not available in ACPI or device tree,
to avoid hard code in drivers. It's only for config items that can be
programmed by SW or FW, not for physical things like link connections
or GPIO used for HP etc.
- Add flags. The flags will be used to configure an existing physical
links.
- Add private data. The private data is reserved for future extension.
- Add name and stream name to physical DAI links. Kernel can also use name
and stream name to find an existing physical link and configure it.
Kernel can handle the ABI update in a backward compatible way via patch
'ASoC: topology: Add support to configure existing physical DAI links'.

Tuples, a pair of token and value, can be used to define vendor specific
data, for controls and widgets. This can avoid importing binary data blob
from other files.
Vendor specific tuple arrays will be embeded in the private data buffer
of a control or widget object. To be backward compatible, union is used
to define the tuple arrays in the existing private data ABI object
'struct snd_soc_tplg_private'.
Vendors need to make sure the token values defined by the topology conf
file match those defined by their driver.
Now supported tuple types are uuid, string, bool, byte, short and word.

Currently the TLV topology structure is targeted at only supporting the
DB scale data. This patch extends support for the other TLV types so they
can be easily added at a later stage.
TLV structure is moved to common topology control header since it's a
common field for controls and can be processed in a general way.
Users must set a proper access flag for a control since it's used to decide
if the TLV field is valid and if a TLV callback is needed.
Removed the following fields from topology TLV struct:
- size/count: type can decide the size.
- numid: not needed to initialize TLV for kcontrol.
- data: replaced by the type specific struct.
Added TLV structure to generic control header and removed TLV structure from
mixer control.

For applications which need to synchronise with external timebases such
as broadcast TV applications the kernel monotonic time is not optimal as
it includes adjustments from NTP and so may still include discontinuities
due to that. A raw monotonic time which does not include any adjustments
is available in the kernel from getrawmonotonic() so provide userspace with
a new timestamp type SNDRV_PCM_TSTAMP_TYPE_MONOTONIC_RAW which provides
timestamps based on this as an option.

Instead of keeping modified asound.h and asequencer.h, copy the files
in the kernel include/uapi/sound as is, and give some renames for
avoiding conflicts with alsa-lib's definitions.
Some structs, unions and typedefs in asound.h and asequencer.h are
once renamed in local.h before inclusion, then renamed back again.
A bonus by this action is that some local codes don't have to refer to
sndrv_xxx any longer. However, some codes like src/seq/seq.c need
explicit cast because of unavoidable conflicts of struct types.
Another significant change is that now snd_pcm_sw_params.period_event

Commit cf40ea169a (pcm: support for audio timestamps) added the new
audio_tstamp field to struct sndrv_pcm_status. However, struct timespec
requires 64-bit alignment, so the 64-bit compiler would insert
32 bits of padding before this field, which broke SNDRV_PCM_IOCTL_STATUS
with error messages like this:
kernel: unknown ioctl = 0x80984120
To solve this, insert the padding explicitly so that it can be taken
into account when calculating the ABI structure size.
