lib: use atomic thread fence recommended API

Use rte_atomic_thread_fence() instead of directly using
__atomic_thread_fence() builtin GCC intrinsic
or __rte_atomic_thread_fence() internal function.

use atomic intrinsics closer to C11

Use __atomic_fetch_{add,and,or,sub,xor} instead of
__atomic_{add,and,or,sub,xor}_fetch when we have no interest in the
result of the operation.

This change reduces unnecessary code that provided the result of the
atomic operation while this result was not used.

It also brings us to a closer alignment with atomics available in C11
standard and will reduce review effort when they are integrated.

lib: remove librte_ prefix from directory names

There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'
