When the range of a control has changed between driver versions, it is a
good idea to restore the same dB value of the control. However,
computing the dB value by interpolating betweem the min/max dB values
duplicates alsa-lib's TLV functions and does not even work for controls
with a linear dB range.
A simple conversion to dB and back can be done if we add the dB value(s)
to the saved state.

Reserving new space from the stack in every loop iteration is not
necessary, so move the call to snd_ctl_elem_id_alloca outside where it
is executed only once.

To save a call to snd_config_set_xxx, replace the calls to
snd_config_make_xxx with snd_config_imake_xxx.

Also, make the initialization & restore logic for one card similar to
multiple card initialization & restore.

To increase configuration readability, add CTL{do_search} and CTL{do_count}
actions. The old PROGRAM=="__ctl_search" notion is also allowed.
Add CTL{write} to XML documentation.

Some HDA codecs have shifted dB range (-34.5dB - 12dB) for PCM and CD
inputs. Use default 0dB value for them.

Another bug/issue I tripped over when compiling alsa-utils in an
environment using uClibc to supply the C library functions. Here I have
enabled some old BSD style functions. The attached patch will honor
them if they are enabled.
Without this patch I get a redefined error during compile.

Fix check when driver contains more controls than state file. In this case,
initialization procedure should be run, too.

By doing this we move them from the .data section to .rodata setion,
or from .data.rel to .data.rel.ro.
The .rodata section is mapped directly from the on-disk file, which is
always a save, while .data.rel.ro is mapped directly when using
prelink, which is a save in a lot of cases.

The initialization procedure consist from default initialization and
state restoration. When restore fails for a reason or the config file
contains inaccurate information, then init is called.
Also, if something fails (init or restore), a file specified using -r
option can be created with description what failed. It can be useful
when user space decides to notify user to set the sound driver properly.
