exp10 is a glibc extension, which isn't supported on uClibc. Luckily,
exp10() is trivial to compute based on exp(), so add a wrapper for
the uClibc case.

Instead of mapping the raw volume values linearly to the screen, use
a mapping where the bar height is proportional to the audible volume,
i.e., where the amplitude is the cube of the bar height.

For controls with a big range, stepping through all values can become
tedious and make it impossible to adjust the volume easily. Therefore,
ensure that all steps are big enough so that the full range has at most
one hundred steps.

Ensure that control volume values are in their allowed range; otherwise,
the displayed values could be outside the range 0..100 and mess up the
layout.

The attempt to divide by max-min fails if a control has only one valid
value. In this case, adjust the maximum so that the computation can
succeed; the control will look like 0%.

Fix the volume bar color selection logic so that the current attribute
is used for inactive controls.

Rename the attr variable because it contains not only the character's
attributes but also the character itself.

When a multi-column character would straddle the left window border of
a text box, we have to take the inserted space character into account
when we compute how many characters fit into the rest of the line.

For multichannel mixer controls, add the channel name to each screen
control.
Also make some other small changes.

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 recent ncurses package provides ncurses*-config program to give the
proper cflags and libs. Let's use them if available.
Right now, the ncurses version (5) is hard-coded. It should be better
to be variable as well, but it'd be messy. Hope the ncurses version won't
change rapidly.
DONE: If alsa-lib and alsa-driver support it,
alsamixer now displays dB gain levels for all mixer controls.
TODO: Implement alsa-lib and alsa-driver parts.
Fixed unexpected abort of alsamixer when no playback or capture elements
are available. Also fixed the wrong use of temporary array in
displaying item name.
alsamixer shows all view names in the View: line so that user
can understand what it means. The currently used view is
shown with brackets and emphasized.
Improved the usability of alsamixer:
- the mute/unmute appears in a separate box below the volume bar
more obviously
- the capture switch appears below the volume bar, too
- the controls without volume doesn't show volume bars
- fixed bugs with all view mode
- fixed the calculation of volume bar size
- show left/right scrollable status
- code clean up
