    evl/mutex: turn user debug options into dynamic settings · 9298420f
    Philippe Gerum authored
    With this rework, we have two separate per-thread mode flags for
    greater flexibility aimed at controlling the debug features on a
    per-thread basis:
    - T_WOSS can be set to trigger SIGDEBUG upon (unexpected) stage switch
      to in-band mode. This is strictly equivalent to the obsoleted T_WARN
    - T_WOLI enables/disables the detection of locking inconsistencies
      with mutexes via the EVL_THRIOC_{SET, CLEAR}_MODE interface. This
      combines the former static CONFIG_EVL_DEBUG_MUTEX_INBAND and
    Enabling CONFIG_EVL_DEBUG_WOLI turns on T_WOLI by default for every
    new EVL thread running in userland, which can be opted out on a
    per-thread basis using EVL_THRIOC_CLEAR_MODE.
