lib: add more logging helpers

Add helpers for logging messages in libraries instead of calling
RTE_LOG() directly.
Those helpers take care of adding a \n: this will make the transition to
RTE_LOG_LINE trivial.

Note:
- for acl and sched libraries that still has some debug multilines
messages, a direct call to RTE_LOG is used: this will make it easier to
notice such special cases,

eal: avoid calling cleanup twice

If an app calls rte_eal_cleanup() inside it's own code, then cleanup
could be called a second time automatically when the app exits. While
mostly harmless, we can avoid any potential issues by guaranteeing that
cleanup only gets called once, in the same way that eal_init only ever
gets called once.

Note: This patch only touches Linux and FreeBSD. Windows EAL does not
have run-once guard on the init function, so omitting it in the cleanup
function.

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'
