Events sent by external clients subscribed to the input port are not
timestamped.
This inconsistent behavior may surprise newbies who look at seq-decoder as
a reference example.
See the example below using "vkeybd --addr 128:0" to connect to seq-decoder,
the events sent by vkeybd are on a different queue with no timestamps:
...
EVENT>>> Type = 66, flags = 0x0, time = 0 ticks
Source = 0.1, dest = 128.0, queue = 253
Event = Port Subscribed; 129:0 -> 128:0
EVENT>>> Type = 66, flags = 0x1, time = 4.829712627
Source = 0.1, dest = 128.0, queue = 0
Event = Port Subscribed; 129:0 -> 128:0
EVENT>>> Type = 10, flags = 0x0, time = 0 ticks
Source = 129.0, dest = 128.0, queue = 253
Event = Controller; ch=0, param=0, value=0
EVENT>>> Type = 11, flags = 0x0, time = 0 ticks
Source = 129.0, dest = 128.0, queue = 253
Event = Program Change; ch=0, program=0
...
After the change events are on the main queue and are timestamped:
...
EVENT>>> Type = 66, flags = 0x1, time = 4.280907223
Source = 0.1, dest = 128.0, queue = 0
Event = Port Subscribed; 129:0 -> 128:0
EVENT>>> Type = 66, flags = 0x1, time = 4.280912063
Source = 0.1, dest = 128.0, queue = 0
Event = Port Subscribed; 129:0 -> 128:0
EVENT>>> Type = 10, flags = 0x1, time = 4.280990702
Source = 129.0, dest = 128.0, queue = 0
Event = Controller; ch=0, param=0, value=0
EVENT>>> Type = 11, flags = 0x1, time = 4.280994862

At kernel v4.14, in initial state, elements on user-defined sets have
write-only flag. When applications write TLV data, then the elements
get readable flag and the TLV data is available. Originally TLV data
is shared by elements in the same set, thus events are generated for
all of elements in the set by the write operation.

A simple multi-thread stress test for PCM is added to test
subdirectory. It can perform various PCM update function in the
worker threads while reading/writing the data in the main thread.
It can help catching the unexpected error or blockage. For example,
running the capture test with a softvol plugin will lead to the assert
due to the races.

Currently, this test program has a bug related to dimension information.
When testing an element set with byte type, the program adds 512 members
to an element. This is a maximum number permitted for this type.
On the other hand, dimension information of the elements consists of
[8, 4, 8, 4]. Calculated members in the multi-dimensional matrix is 1024.
This should be less than 512.

In Linux 4.0 or former, call of ioctl(2) with SNDRV_CTL_IOCTL_ELEM_ADD
doesn't fill all of identical information in an argument; i.e. numid.
With the kernel, a test of user-defined element set fails.
This commit fixes the bug. The 'numid' field in identical information
is always zero when adding an element set, therefore zero check has an
effect.

The feature of control element set has been abandoned for a long time since
firstly introduced in 2003. Furthermore, there's few applications to utilize
this feature. These situations bring a hard work to persons who need the
feature. Especially, a lack of test program make it harder to fix much bugs
in this feature.
This commit adds a test program as a sample of the feature. This program
adds element sets of each element type to 'hw:0' in this order; boolean,
integer, enumerated, bytes, IEC958 and integer64. Each iteration includes
below scheme:
1. add an element set with 900 elements. Each of them has maximum number
of members allowed by ALSA ctl core.
2. check all of events generated by above operation.
3. retrieve information of each element, then validate it.
4. unlock each member of all elements because they're initially locked.
5. write to all of members in all elements and read.
6. check all of events generated by above operation.
7. write information for threshold level to the element set and read it.
8. check all of events generated by above operation.
9. remove the element set.
10.check all of events generated by above operation.
When any of these operations fail, it means regression occurs. Then, added
elements still remain in a certain sound card. In this case, unloading
drivers corresponding to the card is an easy way to recover.
Besides, this program doesn't perform below element operations of ALSA ctl
feature:
- list
- lock
- replace

add new snd_pcm_status_get_audio_htstamp() routine to
query the audio timestamps provided by the kernel.
This change provides applications with better ways
to track elapsed time. Before this patch, applications
would subtract queued samples (delay) from written samples,
resulting in a 1-2 sample error.
Also add snd_pcm_hw_params_supports_audio_wallclock_ts()
to query what the hardware supports.

mixer.h already contains some channel position definitions.
To be more consistent over all systems, better to follow the same
order for the new channel map, too. But since UNKNOWN channel must be
zero but the definition in mixer.h contains -1 as UNKNOWN, simply
shift the value with 1.
If the conversion is required between SND_CHMAP and SND_MIXER_SCHN,
just increment/decrement 1. Eventually I'll provide helper functions
for that...
