[v5,0/6] add thread lifetime and attributes API

  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.

v5:
  * include errno.h in rte_thread.c since errno.h is no longer included
    in rte_common.h
  * move rte_thread_attr symbols from 22.07 to 22.11 section of
    version.map.
  * remove RTE_HAS_CPUSET guards from rte_thread.h
  * change case of characters in commit message for patches {6,5,4} of
    the series.

v4:
  * update version.map to show api from series added in 22.11 instead
    of 22.07.
  * fix missing parameter name in rte_thread_func declaration causing
    doxygen ci failure.

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
