Replaced large struct macros with init functions

Browse Source 
While they are a bit more annoying to call, init functions give the
compiler a chance to deduplicate common struct initialization logic. So
we should probably prefer init functions for any structs larger than a
couple words.

The cost of each init is small, but it really adds up!
