c78ab09473 Cleanup code duplication in malloc on fallback to use another arena

for readability.

6ef9cc37f0 Return requested size for malloc_usable_size when MALLOC_CHECK_ > 0
[BZ #1349]

malloc_usable_size returns the usable size in an allocated chunk,
which may be >= the requested size. In the case of MALLOC_CHECK_ being
exported to > 0 however, only the requested size is usable, since a
magic value is written at the end of the request size to trap writes
beyond request bounds. Hence, when MALLOC_CHECK_ is exported to > 0,
malloc_usable_size() should return the request size.

* malloc.c/arena.c (reused_arena): New parameter, avoid_arena.
        When avoid_arena is set, don't retry in the that arena.  Pick the
        next one, whatever it might be.
        (arena_get2): New parameter avoid_arena, pass through to reused_arena.
        (arena_lock): Pass in new parameter to arena_get2.
        * malloc/malloc.c (__libc_memalign): Pass in new parameter to
        arena_get2.
        (__libc_malloc): Unify retrying after main arena failure with
        __libc_memalign version.
        (__libc_valloc, __libc_pvalloc, __libc_calloc): Likewise.

bec466d922 Fix race in corruption check.
With atomic fastbins the checks performed can race with concurrent

after getting the lock.

bea0ac1d87 Use rel semantics of cas instead of acq semantics with full barrier before it in _int_free
The following patch fixes catomic_compare_and_exchange_*_rel definitions
(which were never used and weren't correct) and uses
catomic_compare_and_exchange_val_rel in _int_free.  Comparing to the
pre-2009-07-02 --enable-experimental-malloc state the generated code should
be identical on all arches other than ppc/ppc64 and on ppc/ppc64 should use
lwsync instead of isync barrier.
