Adrien Destugues 2dc597d50d Optimize ffs() implementation
- Use gcc builtin
- Define as a static inline function in the .h so no function call overhead is needed
- Keep the function in libroot for backwards compatibility
- Remove a duplicate implementation in the freebsd compatibility layer

gcc2 does not document the builtin, but it is in fact already available
there as well.

Fixes #3281.
