Description:
Our array abstractions should be removed, and substituted with modern data
structures.
See e.g. Bug#18556403, Bug#18486249 and other similar bugs.

Templatized vectors are:
 - type safe
 - easier to read/maintain
 - faster

How to repeat:
Read the code

Suggested fix:
Use prealloced_array

Code cleanup. No changelog entry needed.
