Bring back symbol visibility support. This had been done, then backed out,
a long time ago, because I had not realized symbol visibility required a
lot of shared library major bumps to avoid mixed binaries.
However, at the moment, none of the platforms using gcc 3 supports shared
libraries (this is being worked on), and the remaining gcc 2 platforms won't
support gcc 3 until switching from a.out to ELF, which makes the risk of mixing
visibility-unaware binaries with visibility-aware binaries moot.
