macros don't belong here.

The MLINKS should probably be an own patch.

[christos]

Remove macros and MLINKS.

Looks good to me.

No, we do not do it this way. Please look at other libs with symbol version used, for instance libprocstat which seems to be a good example.

There is a single namespace per release, for 14 it is FBSD_1.7. So put the lib' symbols under this version. Versions are defined in lib/libc/Versions.def, again please take a look at libprocstat/Makefile how to reference it.

Also, formally to keep ABI backward compatible we would need to bump libmixer so version, but I do not see a point to go through this relatively painful procedure for head-only library still under development.

[christos]

Fix namespace and referencing.

I also pushed the MLINKS chunks separately.l
