Freddie Chopin 0eeb4c1d32 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

Jeff Johnston c2bbc54a62 Fix atexit logic to honor _ATEXIT_DYNAMIC_ALLOC setting.
If small reent is enabled (_REENT_SMALL is defined) then malloc() was
used in __register_exitproc() even if user requested it to be disabled
(_ATEXIT_DYNAMIC_ALLOC is defined). With this fix, function fails when
_ATEXIT_DYNAMIC_ALLOC is defined and whole static storage is already
used.

        * libc/stdlib/__atexit.c (__register_exitproc): Fix for

Freddie Chopin c39ad27d9e Add missing lock releases in __register_exitproc().
In some code paths the __atexit_lock held by this function was not
released when returning with an error.

        * libc/stdlib/__atexit.c (__register_exitproc): Always release
        lock before return.
