The C11 standard section 7.17.1.4 defines 'memory_order' as the
"enumerated type whose enumerators identify memory ordering constraints".

This issue was hit when trying to compile OVS with gcc 4.8.5. This
compiler version does not provide stdatomic.h, so enum memory_order is
redefined in OVS code.
In another case, if the compiler does provide stdatomic.h header,
passing -Wsystem-headers in the CFLAGS will also cause that failure.

Fix it by changing the argument name 'memory_order' to 'memorder'.

eal/windows: implement alarm API

Implementation is based on waitable timers Win32 API. When timer is set,
a callback and its argument are supplied to the OS, while timer handle
is stored in EAL alarm list. When timer expires, OS wakes up the
interrupt thread and runs the callback. Upon completion it removes the
alarm.

Waitable timers must be set from the thread their callback will run in,
eal_intr_thread_schedule() provides a way to schedule asyncronuous code
execution in the interrupt thread. Alarm module builds synchronous timer
setup on top of it.

Windows alarms are not a type of DPDK interrupt handle and do not
interact with interrupt module beyond executing in the same thread.

For Arm platforms, there are 3 flags in use: RTE_ARCH_ARM,

RTE_ARCH_ARM64 is for 64-bit aarch64 platforms,

RTE_ARCH_ARMv7 is for ARMv7 platforms as its name suggested.

Because no info about platform word length is included in the name.
