```text
Interleaving inclusions of UAPI headers and libc headers is problematic.
Both sets of headers define conflicting symbols. To enable their
coexistence a compatibility-mechanism is in place.

An upcoming change will define 'struct sockaddr' from linux/socket.h.
However sys/socket.h from libc does not yet handle this case and a
symbol conflict will arise.

Move the inclusion of all UAPI headers after the inclusion of the glibc
ones, so the compatibility mechanism from the UAPI headers is used.
