The cgroup.rc file was introduced in 192aee782 ("libprocessgroup: Add
support for task profiles") back with the initial support for task
profiles. It was intended to optimize performance associated with cgroup
operations. However over time, supporting this file led to making
libprocessgroup code more complicated (such as the cgrouprc LLNDK
interface), and the file ended up getting mmaped into nearly every
process on Android even though only a handful of them actually use it.
Replacing this file with reading and parsing of cgroup information on
demand allows us to simplify and shrink libprocessgroup, and eliminates
thousands of unused mappings without negatively affecting boot time or
other performance metrics.

These are for ACgroupController and ACgroupFile, but share a filename
with libcgrouprc_format's CgroupController which can be confusing.

Remove the vestigial llndk_library modules and replace them with
properties in the llndk clause of the implementation cc_library.

The build system will soon require that symbol files describing APIs
across updatable components (e.g. across APEXes or across sytem/vendor)
have the ".map.txt" suffix. This will trigger the NDK API review in the
gerrit so that backwards incompatible changes are prevented.

Instead of assuming a module with the .llndk suffix exists, add an
llndk_stubs property to every cc_library module that has a
corresponding llndk_library. Also rename the llndk_library to have
an explicit .llndk suffix.

Controllers listed in cgroups.json file might fail to mount if kernel is
not configured to support them. We need a way to indicate whether a
controller was successfully mounted and is usable to avoid logging errors
and warnings when a controller that failed to mount is being used. Add
flags bitmask to cgrouprc controller descriptor and use a bit to indicate
that controller is successfully mounted. Modify cpusets_enabled() and
schedboost_enabled() functions to use this bit and report the actual
availability of the controller.

Android build system added support for building translated binaries
used on natively bridged targets (arm on x86 for example).
However in order to avoid building unnecessary binaries and libraries
for such architectures most modules do not support native bridge by default.
All needed modules have to explicitly indicate if they may be used as part
of translated binary build.
This change enabled native bridge support for libprocessgroup modules
needed by libutils greylisted library (available for apps targeting
Android version < N).

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.

This module is an LL-NDK library that can be loaded by
modules that link to libprocessgroup (which is in VNDK).
This module defines APIs that reads cgroups.rc file
programatically. Internally, it uses libcgrouprc_format to
do so.
