Use the LL-NDK library to read cgroup.rc.
As a side-effect, the CgroupController class is changed
to a wrapper of ACgroupController* from the library. The
class itself essentially becomes the pointer, and can be
trivially copied. Modify all client code for this change.

Having shared host libraries allows libraries depending on these to use
'shared_libs' for these. This simplifies configurations since these
libraries don't have to specify 'shared_libs' on all non-host targets.

If the path to android_get_control_file is a symlink, the final sanity
check will fail that the fd does not have the same path as the given
file. We can't expect callers to readlink() because this would change
the environment key. Instead, try to call realpath on both paths.

This patch adds support to make libcutils create and use memfd where
possible, instead of ashmem.
The libcutils library is made dynamic, since apps are still sending over
ashmem FDs to processes and we are working on moving those apps away
from ashmem. The best we can do for that is make the library work, and
force apps in the long run to move away from directly using ashmem.
Due to further complications mentioned in the 'NOTE' section of the
patch, memfd is kept disabled for now, so nothing changes yet. To enable
it, set the sys.use_memfd property (check user_debug build).

In commit f4fc922f0b, we tightened the
permissions on various bin directories. Please see
https://android-review.googlesource.com/c/platform/system/core/+/822955
for details.
This change causes the Chase banking app to crash. This is because
the Chase app is using inotify_add_watch() on the /system/bin directory
and not checking the return value.
The Android Security model guarantees the immutability of files in
/system/bin, so the inotify watch is unnecessary.
Until the Chase app fixes their bug, we need to relax the permissions on
the /system/bin directory. Conceptually, this is a partial revert of
f4fc922f0b.

Currently, /system/bin, /system/xbin, /product/bin, and /vendor/bin
are 0755, which allows any process to iterate through those
directories and list out the contents. For the vast majority of
processes, this is unnecessary. They only need to know whether a
particular binary exists or doesn't exist, but they don't need to
know the other binaries within those directories.
Allowing this is particularly problematic for SELinux. In particular,
some third party Android applications try to examine every file in
the bin directories, generating SELinux audit noise along the
way. This audit noise makes it harder to see real bugs, and falsely
implies an architectural dependency between the application and random
files in directories like /system/bin.
This change removes the ability to list the contents of the various bin
directories, preventing random probing by such apps. The ability to
execute files, or to probe a specific file by name, remain unchanged.
Addresses SELinux denials similar to the following:
avc: denied { getattr } for comm="Thread-11" path="/system/bin/atrace" dev="dm-0" ino=189 scontext=u:r:untrusted_app_27:s0:c512,c768 tcontext=u:object_r:atrace_exec:s0 tclass=file permissive=0 app=uk.co.santander.santanderUK

Callers already verify that they are calling ashmem API on a valid fd by
calling ashmem_valid first. Lets make the fstat syscall only if the
ioctl returns -ENOTTY. This means in the regular case, only 1 syscall is
