[PATCH 5/5] build: don't export internal symbols

[Thomas Haller]

Hide internal symbols from the libraries.
Before, all symbols were exported, including some that were
not meant to be public properties. Hide them now.

This is an ABI break, but nobody was supposed to use these symbols.
Hence it seems acceptable to hide them now.

Still don't hide any symbols that are internal, but wrongly exported
in public header files (such as @ct_obj_ops).
