Add priority level and interface classifiers. Define macros
for all priority level types to keep the callers more readable.
Ensure the compatibility with previous logging mechanism.

config.h may contain defines like _FILE_OFFSET_BITS which influence
the system wide include files (off_t types, open -> open64 function
usage etc.).

This is required so we can make other functions reentrant (such as
snd_device_name_hint()).
The default error handling function snd_lib_error_default() now checks
if a local handler exists, and if so, calls it. Otherwise, the previous
behavior is unchanged.

Activating assert() in the default error message handler isn't always
good for producitve systems. Make this optional and enable only when
a special configure option is given (i.e. for explicit debugging).
Change the handling of non-fatal errors. Now the non-fatal error
messages are not shown in stderr and no assert() as default. The
behavior can be changed with LIBASOUND_DEBUG environment variable.
