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

[Tyler Retzlaff]

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
