In commit b906db19ef, the snd_dlopen()
implements the automatic lookup to the ALSA_PLUGIN_DIR directory.
It is not necessary to add the absolute paths in callers now.
The plugin names are also searched in ld.so.conf paths as the fallback now,
but it should not be a big problem.

The dlopen() function might fail also for another reason than
a missing file, thus return the error string from dlerror().

Currently the whole smixer stuff depends on python, so it doesn't make
sense to install plugins partially when the python support is
disabled.
This patch changes Makefile.am not to install the smixer stuff at all
when the python support is disabled via configure script.

Coverity Static Analysis helps developers find hard-to-spot,
yet potentially crash-causing defects early in the development phase,
reducing the cost,time, and risk of software errors.

This adds extra safety that the built libraries will have all the
correct dependencies linked in.

"./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.

reasons:
- rapid development
- class-like code structure
- more readable code
features:
- hcontrol binding is managed from python (opportunity to create
virtual mixer without driver or join multiple cards to behave as one)
Added --with-configdir and --with-plugindir options to configure
which specify the directories for config files and plugin objects
respectively. The default paths when these options are not
specified are unchanged.
Add --enable-* and --with-pcm-plugins configure options for partial builds.
User can choose the core components (pcm, mixer, rawmidi, hwdep, seq, instr)
via --enable-xxx or --disable-xxx option. As default, all components are
enabled.
The PCM plugins to build can be selected via --with-pcm-plugins option.
For example, to build only rate and linear plugin, pass
--with-pcm-plugins=rate,linear
Passing "all" will select all plugins (it's the default value).
The plug plugin will select linear and copy plugins automatically.
The other auto conversions of plug plugin are enabled only when the
corresponding plugin is selected.
