log: move private functions

Some private log functions had a wrong "rte_" prefix.

All private log functions are moved from eal_private.h
to the new file eal_log.h:
	rte_eal_log_init -> eal_log_init
	rte_log_save_regexp -> eal_log_save_regexp
	rte_log_save_pattern -> eal_log_save_pattern
	eal_log_set_default

The static functions in the file eal_common_log.c are renamed:
	rte_log_save_level -> log_save_level
	rte_log_lookup -> log_lookup
	rte_log_init -> log_init
	__rte_log_register -> log_register
