Why is the speed of light restricted?

I have two questions here:
1. As photons have no mass, why does light have a limited speed?
2. When the special theory of relativity was created, why did people not think that gravity could travel faster than the speed of light, as they (presumably) hadn't come up with the idea of the graviton then?
