[PATCH v3 01/11] devtools: warn when adding some pthread calls

[Thomas Monjalon]

All pthread functions below have an equivalent in rte_thread API:
	- pthread_create
	- pthread_join
	- pthread_detach
	- pthread_setname_np
	- pthread_set_name_np
	- pthread_setaffinity_np
	- pthread_attr_setinheritsched
	- pthread_attr_setschedpolicy
Usage of these functions will be raised to encourage rte_thread adoption.

The pthread functions for locks and cancel are still allowed.
