[nas] [patch] mark some readonly string/params as const

[Stefan Huehner]

Hi,

attached patch marks some read-only string and function parameters as
'const char*' instead of 'char *'. In Addition an unsued buffer
'errfile' from aulog.c was removed.
As the two release.h files are generated the NetAudio.tmpl was modified
to emit the 'const char *' declaration.

Regards,
Stefan
