[PATCH v3 0/6] add thread lifetime and attributes API

[Tyler Retzlaff <roretzla@linux.microsoft.com>]

add rte thread lifetime and attributes api. with these api additions
there is now sufficient platform abstracted thread api to remove the
use of pthread in the unit tests.

v3:
  * change rte_thread_func return type to uint32_t for exit value.
  * change rte_thread_join retval to be uint32_t (matched with the
    return value from rte_thread_func.
  * introduce a wrapper for rte_thread_func on posix platforms to
    adapt differences between rte_thread_func and pthread
    start_routine.
  * remove interpretation / dereference of result from pthread_join
    in posix implementation of rte_thread_join.
  * fix leak of dynamically allocated thread_routine_ctx on windows
    in error paths.
  * don't cast and truncate NULL to integer value for rte_thread_join
    when pthread_join returns no result.

v2:
  * split implementation of rte_thread_equal for windows / posix
    and use pthread_equal for posix platforms.
  * remove parameter validation assertions and instead return
    EINVAL for mandatory pointers to type that are NULL.
  * correct doxygen comment parameter name args -> arg
