[PATCH v16 09/15] eal: initialize log before everything else

In order for all log messages (including CPU mismatch) to
come out through the logging library, it must be initialized
as early in rte_eal_init() as possible on all platforms.
Where it was done before was likely historical based on
the support of non-OS isolated CPU's which required a shared
memory buffer; that support was dropped before DPDK was
publicly released.
