[dpdk-dev] [PATCH v3 1/7] eal: move OS common functions to single file

[talshn@mellanox.com]

From: Tal Shnaiderman <talshn@mellanox.com>

Move common functions between Unix and Windows to eal_common_config.c.

Those simple functions are getter functions for IOVA,
configuration, Multi-process.

Move rte_config and runtime_dir to be defined in a common file.
