config.h may contain defines like _FILE_OFFSET_BITS which influence
the system wide include files (off_t types, open -> open64 function
usage etc.).

A series of SNDRV_CTL_TLVO_XXX macro was introduced for position offset
of TLV data. This commit applies a code optimization.

Current implementation of channel-map TLV on test program is not valid.
Furthermore, it brings buffer-over-run due to byte counting.
This commit fixes it.

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.

Currently, this test program uses undefined type of TLV data. This can
bring confusions to userspace applications.
This commit replaces the array with valid information, constructed by newly
exported TLV macros from kernel land.

In this development period, some APIs have already been added. Most of
them are to add an element set, while their names are not so appropriate
against their feature. This is due to following to names of old APIs.
This commit renames them.

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.
This commit fixes the bug.

In former commits, APIs to add an element set are extended to support extra
fields to information structure. Currently, the fields are mainly used to
describe dimension level.
This commit adds tests to check the dimension level.

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
