b42e8b4dec Add option to force memunreachable check. 
The new option is named check_unreachable_on_signal. It is meant
to duplicate dumpsys meminfo --unreachable <PID> for non-java
processes. When enabled, a user can send a signal to a process
which will trigger the unreachable check on the next allocation
call.

Added new unit tests.

Test: New unit tests pass.
Test: Enabled for the entire system, then dumped on the netd
Test: process and also system_server.

b65e105047 add new Linux close_range() system call to bionic 
See:
  https://man7.org/linux/man-pages/man2/close_range.2.html

Note: 'man close_range' documents 'flags' as unsigned int,
while glibc unistd.h as just 'int'.  Picking 'int' to match glibc,
though it probably doesn't matter.

Christopher Ferris
f78486f40e Mangle the pointers stored in PointerData. 
The libmemunreachable library looks through memory to determine
if pointers are leaked. Unfortunately, the malloc debug code
stores the original pointer in data structures, so it looks like
pointers are still in use. The fix is to mangle the pointers
stored in memory so that it doesn't trick the library into thinking
they are live.

Test: All unit/system tests pass.
Test: Ran libmemunreachable and verified leaks show up.

a0745cea5f seccomp: allow stat() for ubsan. 
We've had complaints about ubsan issues for years, but never got to the
bottom of them, or saw them ourselves in testing. For some reason (still
not understood) we've started to see this ourselves in T and downstream
branches. So for now, let's just punch that extra hole.

Longer term, ubsan should stop needing any of this, so once
https://reviews.llvm.org/D124212 is in an LTS NDK, we should be able to
get rid of this _and_ the existing sanitizer-related holes.

c9c0ebde3c allowlist new Linux close_range() system call, use it in posix_spawn() 
Linux kernel's close_range() system call (currently) allows:
  close() unshare() fcntl(F_SETFD, FD_CLOEXEC)
to be performed on ranges of fds.

All 3 of these are already allowed by seccomp bpf:
as such this doesn't allow you to do anything you can't already do.

We can't add close_range() properly to bionic because we'd need to
fiddle about with ltp and it's too late to add new T API anyway,
so let's just make the direct syscall() call.

We'll add proper support in U.
