7fda8d2aa4 Implement setjmp cookies on ARM. 
Reuse the top bits of _JB_SIGFLAG field previously used to store a
boolean to store a cookie that's validated by [sig]longjmp to make it
harder to use as a ROP gadget. Additionally, encrypt saved registers
with the cookie so that an attacker can't modify a register's value to
a specific value without knowing the cookie.

569333293a Fix the way to get main thread stack start address. 
For previous way to get the stack using the [stack] string from
/proc/self/task/<pid>/maps is not enough. On x86/x86_64, if an
alternative signal stack is used while a task switch happens,
the [stack] indicator may no longer be correct.

Instead, stack_start from /proc/self/stat which is always inside
the main stack, is used to find the main stack in /proc/self/maps.

efc134dba3 Only close stdin/stdout/stderr for debug malloc. 
The debug malloc code unconditionally closes stdin/stdout/stderr,
which means that other atexit functions cannot use them. Only
close these if there is a debug malloc final function to call.

This doesn't appear to be a problem on most normal applications or the
atexit_exit bionic unit test would be failing. However, if you
enable stat dumping in jemalloc, nothing prints. Most likely trying
to add an atexit function from within libc is causing that atexit
to run after the debug malloc atexit function.

edfc9f63a2 linker: don't pass dlextinfo to dependent loads 
Don't pass the parent load's dlextinfo to dependent loads, since this
causes the linker to try to load the dependencies using the same
addresses/relro/fds/etc as the main library, which is never going to
work. This was how it worked before ae69a95 which broke this.
