Change assert condition in error message handler

Browse source 
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).

@ -27,12 +27,15 @@ LIBASOUND_DEBUG is set (to a non-empty value).
When LIBASOUND_DEBUG=1 is set, the errors in hw_params configuration
will be dumped to stderr. Note that this will show even the non-fatal
errors of plug layer (trial-and-error of parameters).
When LIBASOUND_DEBUG=2 is set, the default error message handler calls
assert() to catch with a debugger, in addition to parameter debugging.
This feature is disabled when --with-debug=no is passed to configure,
i.e. no strict checking is done in alsa-lib.
In addition, when --enable-debug-assert configure option is given and
when LIBASOUND_DEBUG_ASSERT=1 is set, the default error message
handler can call assert() to catch with a debugger. This feature was
formerly activated via LIBASOUND_DEBUG=2.
