Now that we always have system mounted early, we're starting to load
various daemons during the `init` trigger and these daemons need the
environment set up from init.environ.rc, so we move it to early-init.
This shouldn't need to go any further earlier in the future, since
nothing besides ueventd should ever start in early-init.
Test: systems boot, early daemons get right environment

libandroidicu is used by various libraries, e.g. libxml2, minikin.
Thus, expose libandroidicu to default namespace.
libpac is only used by libjni_pacprocessor (part of framework).
libicuuc, libicui18n are not exposed to default namespace,
because everyone else, except app, should use libandroidicu.
They are exposed to classloader namespace from runtime namespace
via the work done in libnativeloader in http://r.android.com/887453

Originally, vndk_lite does not include system/lib/vndk-* directory but
searching the required files in system/lib instead. However, in GSI,
they are using the vndk libs which has symbols than core variants.
To avoid this problem, allow the vendor processes in vndk_lite devices
to search system/lib prior to vndk libs.

This change fixes the problem that apexd is delaying the entire boot
sequence while waiting for the loopback devices to be created. The delay
was as big as 50 ms per a loopback device.
With this change, apexd is started much earlier: from "on post-fs-data"
to "on init". When it is first started, it scans /system/apex to
determine the number of APEXes and creates that number of loopback
devices priori. Since then it enters into the binder loop.
When the data partition is mounted, init lets apexd to initiate the
apexd boot sequence where APEXes in /data is scanned, verified, and
activated. Since the creation of the loopback devices were requested far
before, it is very likely that dev nodes for the devices are ready at
this moment (even if not, this isn't a lose).

The sys.use_memfd property is set by default to false in Android
to temporarily disable memfd, till vendor and apps are ready for it.
The main issue: either apps or vendor processes can directly make ashmem
IOCTLs on FDs they receive by assuming they are ashmem, without going
through libcutils. Such fds could have very well be originally created with
libcutils hence they could be memfd. Thus the IOCTLs will break.
Set default value of sys.use_memfd property to true once the issue is
resolved, so that the code can then self-detect if kernel support is present
on the device. The property can also set to true from adb shell, for
debugging.

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.

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.

This CL fixes the design problem of the previous mechanism for providing
the bootstrap bionic and the runtime bionic to the same path.
Previously, bootstrap bionic was self-bind-mounted; i.e.
/system/bin/libc.so is bind-mounted to itself. And the runtime bionic
was bind-mounted on top of the bootstrap bionic. This has not only caused
problems like `adb sync` not working(b/122737045), but also is quite
difficult to understand due to the double-and-self mounting.
This is the new design:
Most importantly, these four are all distinct:
1) bootstrap bionic (/system/lib/bootstrap/libc.so)
2) runtime bionic (/apex/com.android.runtime/lib/bionic/libc.so)
3) mount point for 1) and 2) (/bionic/lib/libc.so)
4) symlink for 3) (/system/lib/libc.so -> /bionic/lib/libc.so)
Inside the mount namespace of the pre-apexd processes, 1) is
bind-mounted to 3). Likewise, inside the mount namespace of the
post-apexd processes, 2) is bind-mounted to 3). In other words, there is
no self-mount, and no double-mount.
Another change is that mount points are under /bionic and the legacy
paths become symlinks to the mount points. This is to make sure that
there is no bind mounts under /system, which is breaking some apps.
Finally, code for creating mount namespaces, mounting bionic, etc are
refactored to mount_namespace.cpp
