Summary: Do not export lsx_ symbols in libsox
Initial Comment:
If you look at the public symbols in libsox, you'll see a lot of symbols that we do not advertise as part of the SoX API. They have all been prefixed with lsx_ to help distinguish them.
It would be nice to not export those as public symbols. Most obvious option is to make use of -retain-symbols-file where it is supported.
I think I've also seen attempts to do this at compile time by png.h (not sure if it works or worth the trouble it looks like it causes).

Message:
This can, in principle, be easily done via libtool's -export-symbols-regex
option ("-export-symbols-regex '^sox_'").
However, SoX-the-application uses several internal functions (see "nm -Du
`which sox` | grep lsx_"), and the modules built via --with-whatever=dyn
some more. Therefore, the regex to use is more like:
"^(sox_.*|lsx_(check_read_params|(close|open)_dllibrary|(debug(_more|_most)?|fail|report|warn)_impl|eof|fail_errno|filelength|find_(enum_(text|value)|file_extension)|getopt(_init)?|lpc10_(create_(de|en)coder_state|(de|en)code)|raw(read|write)|read(_b_buf|buf|chars)|realloc|rewind|seeki|sigfigs3p?|strcasecmp|tell
|unreadb|write(b|_b_buf|buf|s)))$"
Still, this hides about 90% of the private symbols, so I think I will
actually add this, as a step in the right direction.
To deal with the rest, we'd need to create a self-contained helper library
that can be linked (statically) into the modules, and into
SoX-the-application. But it is probably difficult to make it
self-contained, as those functions in turn call more internal functions,
etc.
