fe8bb13400 dmix skipping first set of samples 
There was a change in alsa-lib 1.0.16 which looks like it was designed to
make dmix skip samples in the case of underruns, but it causes the first
sample to be skipped since dmix->slave_hw_ptr == dmix->slave_appl_ptr.
The following patch fixes this and fixes a small typo in the comment.

d587383d6b Fix for alsa-lib cross-compilation problems with ALSA_CONFIG_DIR and ALSA_PLUGIN_DIR 
"./configure" options for selecting ALSA configuration (default
/usr/share/alsa) and plugin (/usr/lib/alsa-lib) directories introduced
by alsa-hg/alsa-lib changeset 2284 cause problems with cross-compilation
and packaging - there is no way to redefine them in runtime, during
installation phase.

This patch adds a level of indirection between constants and their
usage - alsaconfigdir for ALSA_CONFIG_DIR and alsaplugindir for
ALSA_PLUGIN_DIR - which can be redefined during "make install" stage.

86456d21e0 revert revision 2264:23c4c0f5de40 
The rounding done when converting to smaller sample widths fails for
saturated positive samples; in this case, the sample value overflows and
becomes negative.  We are better off without rounding, even if we then
have quantization noise (of at most half the resolution of the least
significant bit).

8a035282ac Clean up Versions file 
The entries in the current Versions file don't work as expected.
Since the first ALSA_0.9 has already snd_* global definitions, all
the rest are simply ignored.  Some symbols (e.g. snd_hw_params_*)
indeed work because they have explicit symver definitions, but
ALSA_0.9.6 and later are all superfluous.

This patch clean up these useless entries.  Also, the patch restricts
the matching patterns for _snd_* and __snd_* entries to reduce the
unneeded export symbols.
