Subject: [PATCH] Sort headers/global definitions to enable reproducible code
generation
headers and global_declarations are generated by methods that return
sets. So even with the same inputs it is not guaranteed that the same
source code is generated since sets do not guarantee a specific order
when iterating over them.
