Pass -fvisibility-inlines-hidden to g++
This reduces the number of symbols by about 10%. Unfortunately,
it does not seem to cover all the weird std::vector and friend
template expansions.
ABI should not brake due to that change: It was never specified
before whether an inline symbol was exported or not; so no library
could rely on its presence. Instead, the symbols were exported in
each library/program needing it and and then merged into a common
one by the dynamic linker.
Also update the symbol files to account for the removed symbols.
