alsaucm: Add Use Case Manager utility
alsaucm is a command line tool that can be used to generate and debug UCM
configuration files. The alsaucm utility can fully use the UCM functionality
to query and configure all the UCM functionality in alsa-lib.

alsactl: correctly restore dB values of controls with changed range
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.

alsamixer: fix division by zero
The attempt to divide by max-min fails if a control has only one valid

Rather than having numerous preprocessor directives scattered in the code
checking __BYTE_ORDER, only check it once and define a set of macros
accordingly that can be used in the rest of the code. This makes things

alsa-utils check if __USE_BSD is defined before compiling "BSD functions"
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.

speaker-test: Fix floating-point exception bug
The period_size an buffer_size parameters must be taken after calling
snd_pcm_hw_params(). Otherwise they could be undefined numbers.
For example, period_size gets 0 when pcsp driver is used, resulting in
a floating-point exception error.
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.

Move conditional inclusion of locale.h further down.
Without this patch, ENABLE_NLS is checked before ever being defined
(aconfig.h is not yet included), and thus locale.h would never be
