config.h needs to be consistently included before any standard headers if we ever want to set feature test macros (like _GNU_SOURCE or whatever) inside. It can lead to hard-to-debug issues without that. It can also be problematic just for our own HAVE_* that it may define if it's not consistently made available before our own headers. Just always include it first, before everything. We already did this in many files, just not consistently.
