While calculating the size of data to be written into the topology
binary file, the size of the compound elements is added as well. This
results in wrong file offset calculation and topology build failure.
The compound elements shouldn't be written to the topology as these are
already embedded as part of other elements. So, skip adding the size of
compound elements to the file offset size calculation.

The previous patch has added 20-bit PCM formats SND_PCM_FORMAT_{S,U}20 to
alsa-lib.
We need to extend the linear format conversion code with handling of these
sample formats so they can also be utilized by applications that only
recognize the more typical ones like SND_PCM_FORMAT_S16.
Since the conversion arrays are indexed by a format bit width divided by 8
the easiest way to handle these formats is to treat them like they were
40-bit wide (the next free integer multiple of 8 bits).
This doesn't create a collision risk with a future format since there can't
really be a 40-bit sample format that occupies 4 bytes.
Make sure we use the getput conversion method for these formats since a
direct conversion from / to them is not supported.

In ALSA control interface in asound.h, 'struct snd_ctl_elem_info' has
'dimen' member to deliver information for multi-dimensional array, however
there's no common way to handle the member. As a result, drivers can
force userspace applications to handle the information by inconsistent
ways.
This issue was reported by a commit 51db452df07b ('Revert "ALSA: echoaudio:
purge contradictions between dimension matrix members and total number of
members"') to Linux kernel. As a result of discussion at Linux
miniconference 2017, usage of 'dimen' member of 'struct snd_ctl_elem_info'
is going to be deprecated for future removal.
A removal of kernel interface can cause regression issues. However no ALSA
driver in kernel land except for 'echoaudio' series utilizes this feature.
Actually it's reasonable to assume that 'echomixer' program is an unique
consumer of the interface in user land and the removal rarely brings any
impact to user land.
This commit deprecates some APIs corresponding to the kernel interface. The
kernel interface is kept till Linux kernel v4.20 at least, but actual
timing of removal is not fixed yet. After that, these APIs may also be
removed at a reasonable timing.

PulseAudio assumes that the "front" pcm device always refers to an
analog device, not HDMI. While that assumption is not really valid, the
reality is that without that assumption PulseAudio can't know whether
"front" and "hdmi" refer to a different or the same device.
The HDMI LPE driver doesn't allow audio streaming while the HDMI cable
is unplugged, so PulseAudio has to know when it's plugged in and when
it's not. If both "front" and "hdmi" devices exist, PulseAudio will
notice that HDMI is unplugged, but it doesn't know that "front" refers
to the same device, and PulseAudio will try to use the "front" device
with bad consequences. The kernel driver's refusal to stream any audio
makes PulseAudio enter an infinite loop and then the kernel kills
PulseAudio, because it consumes too much CPU time in a realtime thread.
While the looping in PulseAudio could probably be fixed, that wouldn't
change the fact that PulseAudio thinks that there is an analog device. I
believe it's best to avoid having the same device as both "front" and
"hdmi" in alsa-lib.
I removed also the surround configuration includes. I don't think they
had any effect anyway, so I wonder why they were there in the first
place.

As suggested in POSIX[1], wordexp might execute the shell. If the libc
implementation does so, it will break the firefox sandbox which does
not allow exec. This happened on Alpine Linux with musl libc[2].
Since we cannot guarantee that the system wordexp implementation does
not execute shell, we cannot really use it, and need to implement the

We provide a configure option --with-wordexp for users that still may
need it, but we leave this off by default because wordexp is a large
