There are not that many places errors can occur and the library itself is designed to not allocate additional memory (except for file buffers). Handling errors in one place reduces the number of possible branches and therefore may positively impact performance and code size.

I have an implementation of this locally. There's a slight increase in performance and code complexity is reduced too. Likely ends up in the work done for #19.

Add fallback implementation
f01fc0a 
Add a fallback implementation to support architectures for which no SIMD
implementation is available yet. Sources have been reorganized to allow
for easy optimization per target. Closes NLnetLabs#4.

Use longjmp for error handling. Closes NLnetLabs#1.

Add zone-bench to allow for convenient benchmarking.

Vectorize string to wire conversion. Closes NLnetLabs#20.

Vectorize name to wire conversion. Closes NLnetLabs#29.
