[LV2] lilv static library

[Stefan Kersten]

hi,

i hope this is the right place to discuss issues related to lilv, if not, please
let me know.

i'd like to build lilv (+ serd, sord) as a static library on iOS (no dynamic
linking on that platform) and came across a problem with symbol name clashes
from the zix_* modules in lilv and sord. for now i just added a prefix to each
symbol for each library, but it would be nice to have a cleaner solution.

would it be possible to add zix as a separate library that could be built
statically? it seems that lilv and sord use slightly different tree
implementations, but maybe they could be unified? of course i will try to help
where i can ...

thanks,
<sk>
