*/build.prop files are now loaded much earlier than before; from 'on
post-fs' to the time when the property service is started which is
before init starts the action loop.
This ensures that all processes that are launched by init have a
consistent view of system properties. Previously, the processes that
started before 'on post-fs' were initially with the small number of
sysprops loaded from */default.prop and then suddenly get additional
sysprops from */build.prop while they are executing.

Bionic libs, regardless of whether they are bootstrap ones or from the
runtime APEX, are available via /system/lib. Since /system/lib is in the
search paths of the default(platform) namespace, there is no need to
list the bionic libs to the namespace link to the runtime namespace.

This change makes the bionic libs and the dynamic linker from the
runtime APEX (com.android.runtime) available to all processes started
after apexd finishes activating APEXes.
Specifically, the device has two sets of bionic libs and the dynamic
linker: one in the system partition for pre-apexd processes and another
in the runtime APEX for post-apexd processes. The former is referred as
the 'bootstrap' bionic and are located at
/system/lib/{libc|libdl|libm}.so and /system/bin/linker. The latter is
referred as the 'runtime' bionic and are located at
/apex/com.android.runtime/lib/bionic/{libc|libdl|libm}.so and
/apex/com.android.runtime/bin/linker.
Although the two sets are located in different directories, at runtime,
they are accessed via the same path: /system/lib/* and
/system/bin/linker ... for both pre/post-apexd processes. This is done
by bind-mounting the bootstrap or the runtime bionic to the same path.
Keeping the same path is necessary because there are many modules and
apps that explicitly or implicitly depend on the fact that bionic libs
are located in /system/lib and are loaded into the default linker
namespace (which has /system/lib in its search paths).
Before the apexd is started, init executes a built-in action
'prepare_bootstrap_bionic' that bind-mounts the bootstrap bionic to the
mount points. Processes started during this time are provided with the
bootstrap bionic. Then after the apexd is finished, init executes
another built-in action 'setup_runtime_bionic' which again mounts the
runtime bionic to the same mount points, thus hiding the previous mounts
that target the bootstrap bionic. The mounting of the runtime bionic
(which is only for post-apexd processes) is hidden from pre-apexd
processes by changing propagation type of the mount points to 'private'
and execute the pre-apexd processes with a new mount namespace using
unshare(2). If a pre-apexd process crashes and re-launched after the
apexd is on, the process still gets the bootstrap bionic by unmounting
the runtime bionic which effectively un-hides the previous bind-mounts
targeting the bootstrap bionic.

For consistency with APKs, signature verification is performed
in the system_server. This includes checking that the signature of
an updated install matches the signature of the active package that
it updates. For this, it requires search access to /data/apex and
read access to the files under that directory.

This commit removes the soname filter from the namespace fallback link
from `runtime` to `system` in the vendor process. This fixes the
problem that vendor process might fail to load `libnetd_client.so`,
`libc_malloc_debug.so`, `libc_malloc_debug_leak.so`, and other libc
dependencies.
This commit also removes the namespace fallback link from `runtime` to
`default` in the vendor process. According to the comments in [1], the
original intention was to allow the access to `/system/${LIB}` not
`/vendor/${LIB}`. Furthermore, `com.android.runtime` suppose to work
without libraries from `/vendor/${LIB}`.

This reverts commit a0d9f2fd6c.
Original change: Needs to support e.g. app_process in "default" ->
libnativehelper in "runtime" -> platform libs in "default" -> libc etc in "runtime".
Always make sure to switch namespaces when switching library paths between
/system and the APEX, so that internal library dependencies in both
locations are loaded from their own directory. E.g. libc++ and libbase live
in both places, and their dependents must always load the version they were
compiled with.
This CL also adds a temporary workaround to not break hwasan builds
(b/121038155).
