Added statistics for every type of table. By default all table statistics
are disabled, user must activate them in config file.

Changes in v2:
	- added missing signoffs

Changes in v3:
	- removed new config options to enable/disable stats
	- using RTE_LOG_LEVEL instead

Changes in v4:
	- created single config option for all table statistics

Changes in v5:
	- added missing CONFIG_ prefix to defines in config files
	- added stub table stats
	
Maciej Gajdzica (11):
  table: added structure for storing table stats and config option
  table: added acl table stats
  table: added array table stats
  table: added hash_ext table stats
  table: added hash_key16 table stats
  table: added hash_key32 table stats
  table: added hash_key8 table stats
  table: added hash_lru table stats
  table: added lpm_ipv6 table stats
  table: added lpm table stats
  table: added stub table stats
