It may be possible that the controls are quickly added and
removed, thus the "hard" fail is not optimal here.

In commit "ae9ddeb63443cc2c46e0f0b915466cca0f800372" the rint() was
changed to ceil(). Revert it back. The rint() rounding is more precise
for most cases.
Also, handle the special case where the percentual value is greather
then zero. Set the min + 1 value in this case.
At last, fix the return value in convert_prange() when range is zero.

According to kernel code (snd_ctl_elem_init_enum_names() in
sound/core/control.c), the maximum length of item name is 63 characters
(+ 1 terminator = 64 bytes). But current amixer implementation
uses 40 bytes. This causes name truncation and fail to operation.
This commit fixes this bug by expanding the length of local variables.

So far amixer allows some unexpected suffix and assumes as a raw
absolute value without returning an error. This is rather dangerous,
e.g. user might not notice that a completely wrong value was set when
the command line included a typo.
This patch makes the parser a bit more strict: it doesn't allow any
longer invalid suffixes, instead either returns an error or skips the
invalid value, depending on the operation mode.

decode_tlv() adds indentation in the beginning, with the expectation
that the TLV will be printed on the line afterwards in a switch-case.
However, in the case of a container TLV the switch-case simply adds
another level of indentation and calls decode_tlv() for the inner TLVs.
This causes the first inner TLV to be printed with too much indentation
and double '|'.
Fix that by printing "container" and a newline for container TLVs, so
that the result is as follows:
: values=0,0,0,0,0,0,0,0
| container
| chmap-variable=FL,FR
| chmap-variable=FL,FR,LFE
| chmap-variable=FL,FR,FC

Due to a wrong indexing of tlv[] decode_tlv() always skips to the end of
the container TLV since the used tlv[1] contains the container TLV size
instead of the intended element size.
This causes, for example, only the first HDMI channel map TLV to be
shown.
Fix the indexing to actually use the element size.

When doing control changes by a relative amount, amixer used the wrong

When -M option is given, amixer handles the volumes in percent unit
with the mapping more intuitive to human ears just like in alsamixer.
The -R option is to take the raw value as the volume percentage.

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.

cset accepts only integer values as indices, so far, but it's a bit
unfriendly. Now it accepts the item name as a string argument, too.
The index can be given using numbers as fallback.
The item names with channel specifier cannot be chosen correctly
via amixer sset. For example, 'Front Mic' is handled as 'Mic' since
the channel specificier 'Front' is omitted.
The idea of channel specifier is basically non-sense for enum items,
and this also makes the code very messy.
The patch fixes the behavior of enum items and gives the code clean-up
for sset command.
