Hi Carl,

Can we try to avoid adding new dependencies to mesa unless absolutely
needed. Neither of the proprietary drivers does so presently, so it will
be nice to keep the trend.

While currently the steam runtime does not include libnettle I can
envision one day that they will/might. Even with steam aside I think
that this might cause issues with gnome & others' sandboxing.

Long story short - can we import a sha1 implementation from another
project ? It will save us the "libstdc++ style steam runtime" issues,
plus it will ease the question of what to do under Windows :)


Thanks
Emil
