If libcutils is not a VNDK version and /dev/ashmem is not available,
then ask ashmemd for opened fd to /dev/ashmem.
We rely on SELinux policy to determine what's allowed to open
/dev/ashmem directly.

We already know that "polling" must be non-zero at this point,
because it hasn't been modified since our check on line 1960.
So we remove this check for code clarity.

We want our default implementations to fail, but '-1' is implicitly
cast to 'true', since it's non-zero. We explicitly use 'false' to
fix this.

Non-android targets should not mount cgroups described in cgroup map
file. When used on non-Android targets SetupCgroup will fail. When
SetupCgroup is called via SetupCgroups a warning will be generated for
each cgroup that fails to mount.

Non-Android build targets are missing sys/prctl.h header and functionality
should be disabled for them like it was done previously inside
sched_policy.cpp. Also make the set_sched_policy/get_sched_policy
functionality backward compatible by creating stubs for non-Android
targets.

Abstract usage of cgroups into task profiles that allows for changes
in cgroup hierarchy and version without affecting framework codebase.
Rework current processgroup and sched_policy API function implementations

Add cgroups.json and task_profiles.json file to be places under /etc/ on
the device to describe cgroups to be mounted and task profiles that
processes can request. This adds additional layer of abstraction between
what a process wants to achieve and how system implements that request.

With new psi monitor support in the kernel lmkd can use it to register
custom pressure levels. Add lmkd support for psi monitors when they are
provided by the kernel and use them by default. When kernel does not
support psi lmkd will fall back to vmpressure usage.
Add ability to poll memory status after the initial psi event is triggered
because kernel throttles psi memory pressure events to one per PSI tracking
window (currently set to 1sec). Current implementation polls every 200ms
for 1sec duration after the initial event is triggered.
If ro.lmk.use_psi is set to false psi logic will be disabled even when psi
is supported in kernel.

Reimplement commit ffc11d3cf3 using
fdevent. The previous attempt was reverted because we were blindly
continuing when revents & POLLIN == 0, which ignored POLLHUP/POLLERR,
leading to spinloops when the opposite end of the file descriptor was
shutdown when we had no data left to read.
This patch reimplements the functionality implemented by that commit
using fdevent, which gets us detection of spin loops for free.

The vulkan runtime loads drivers into the sphal namespace and relies
on them being in the sphal search path so that it doesn't have to
hardcode /vendor/${LIB}/hw.
These paths used to be allowed, but were removed by commit 2498e1b
because they were believed not to be required. Things didn't break
immediately because the vulkan runtime has a (supposed to be
temporary) fallback to hw_get_module, which loads from
/vendor/${LIB}/hw using absolute paths.
