26a8322972 Move several FreeBSD functions to OpenBSD. 
There's no difference between the two BSDs for these functions, so let's go
with the majority.

5ca66528c5 make mmap fail on requests larger than PTRDIFF_MAX 
Allocations larger than PTRDIFF_MAX can be successfully created on
32-bit with a 3:1 split, or in 32-bit processes running on 64-bit.

Allowing these allocations to succeed is dangerous, as it introduces
overflows for `end - start` and isn't compatible with APIs (mis)using
ssize_t to report either the size or an error. POSIX is guilty of this,
as are many other Android APIs. LLVM even considers the `ptr + size`
case to be undefined, as all pointer arithmetic compiles down to signed
operations and overflow is treated as undefined for standard C pointer
arithmetic (GNU C `void *` arithmetic works differently).

This also prevents dlmalloc from allocating > PTRDIFF_MAX as it doesn't
merge mappings like jemalloc. A similar check will need to be added in
jemalloc's code path for huge allocations.

The musl libc implementation also performs this sanity check.

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.

32bf43f44a Rename debug_stacktrace to debug_backtrace. 
All the functions say "backtrace", so it's weird that the filename
says "stacktrace".
