- add snd_device_name_hint() and snd_device_name_free_hint() functions
- add snd_ctl_iface_conf_name() functions
- do not accept parameters for the plugin definition without @args section
- add defaults.pcm.dmix.card/device and dsnoop.card/device definitions
- add hints for HDA-Intel.conf, pcm/dmix.conf, pcm/dsnoop.conf and alsa.conf
- add test/namehint test utility
- doxygen related cleanups
Use dmix/dsnoop for maestro3 boards. Although maestro3 has multiple
playback capability, it supports only two streams (with the currently
available firmware).
If volume or switch write fails, the internal contents for element
is changed, but it is wrong. Reread the whole simple element in this
case to get correct values.
Make sure that the rate plugin does not try to change the slave's
boundary value when setting software parameters; such a change wouldn't
affect the slave pcm.
Furthermore, the stop_threshold conversion code used the wrong boundary
value, and the silence_size conversion code did not take into account
the boundary value at all.
the alisp.c file includes wordexp.h even though it doesnt actually use any
wordexp functions ... causes trouble when target doesnt have wordexp
support :)

the src/names.c file includes many more headers than it actually needs ...
this causes troubles when porting to a target that lacks those headers :)

safe_strtoll() now accepts numbers in any base. It formerly assumed that
its input was a decimal number, which had the consequence that
hexadecimal or octal numbers would be parsed as strings when occurring
outside of parameter lists.
This obsoletes some workarounds in the file permission parsing code that
relied on this bug.
Check whether non-zero size TLV is really returned by comparing
with the pre-filled pattern. ALSA 1.0.12 driver doesn't notify
the error even if user TLV is empty, so the previous value is
passed bogusly.
This patch fixes a build issue on systems with Gnu assembler
prior to 2.15.92. Instead of having the inline assembler
translate the leal function on a 32 bit register, it is byte encoded.

snd_hctl_wait() currently makes a lot of assumptions that fall outside
the defined API. snd_pcm_wait(), however, follows the API nicely so the
new version is based on that.

Some io plug-ins might want to adjust the reported delay value and not
strictly follow the current buffer usage (that's why we have two calls
after all).
Allow them to specify a delay() callback and use the previous behaviour
if they don't.

When this new parameter is specified, the behavior of opening a file PCM
for input is changed to the following: reads from the device, instead of
being passed down to the slave PCM, will read the raw data from the
specified file. No file writes will take place in this case. In the
absence of this parameter, previous behavior is unchanged.
The input file name and descriptor are kept in the snd_pcm_file_t struct
in a manner analogous to the already existing output file parameter.
TODO:
(1) Only interleaved reads (snd_pcm_file_readi) have been implemented
for now.
(2) File read()'s that return a number of bytes that's not a multiple of
the frame size will result in data loss (choppiness). The rbuf,
rbuf_size_bytes, and rbuf_used_bytes members of the snd_pcm_file_t
struct will be used to address this problem in the future.
(3) Mind whether the PCM was opened in blocking mode. If so, we'll have
to loop until the buffer has been filled with read()'s.
