Use default symbol visibility for everything.

Almost no symbols were being exported because we were using the wrong
config. The only way everything was working was because a bug in our
build system where the .o files were also being linked into consumers of
the .so.

The -Wl,-Bsymbolic flag also needs to be used because otherwise the
assembly code needs to be modified to handle different types of
relocations referencing internal symbols that are now being exported.
