At least on Arch linux ARM, the definition of struct stat in stat.h depends
on __USE_FILE_OFFSET64. This symbol comes from config.h when defined,
therefore config.h must always be included before stat.h. Fix all
occurrences where the order is wrong by moving config.h to the top.

This fixes the client side error "Stale file handle" when mounting from
a server running Arch Linux ARM.
