malloc: Check for integer overflow in valloc.
A large bytes parameter to valloc could cause an integer overflow and corrupt allocator internals. Check the overflow does not occur before continuing with the allocation. ChangeLog: 2013-09-11 Will Newton <will.newton@linaro.org> [BZ #15856] * malloc/malloc.c (__libc_valloc): Check the value of bytes does not overflow.
