commit 0eeb4c1d32aab0dbfd2a8f20aa326ae2d98ca1c6
Author: Freddie Chopin <freddie.chopin@gmail.com>
Date:   Sun Jan 29 10:27:17 2017 +0100

    Unify names of all lock objects
    
    In preparation for the patch that would allow retargeting of locking
    routines, rename all lock objects to follow this pattern:
    
    "__<name>_[recursive_]mutex".
    
    Following locks were renamed:
    __dd_hash_lock -> __dd_hash_mutex
    __sfp_lock -> __sfp_recursive_mutex
    __sinit_lock -> __sinit_recursive_mutex
    __atexit_lock -> __atexit_recursive_mutex
    _arc4random_mutex -> __arc4random_mutex
    __env_lock_object -> __env_recursive_mutex
    __malloc_lock_object -> __malloc_recursive_mutex
    __atexit_mutex -> __at_quick_exit_mutex
    __tz_lock_object -> __tz_mutex
