The permitted and search paths should be changed according to VNDK
version for VNDK snapshot. So, {VNDK_VER} value is added in ld.config.txt
file and this value is set through the linker.
If ro.vndk.version is not set, search paths are vndk and vndk-sp as
before.

This reverts commit 81b175747d.
Reason: 02586a2a34 fixed the bug that
prevented us from using LD_PRELOAD with multiple namespaces.

2. enable talkback shortcut
3. in the home screen, hold vol-up/down together
4. device does not reboots and talkback shortcut is toggled

Linker resolves the paths in /system/etc/ld.config.txt to canonicalize
the paths and to ensure they exist. However, as permitted paths for the
default namespace contain directories such as /vendor/app, /mnt/expand,
and etc., the resolving causes selinux denial on some processes which do
not have access to some of the permitted paths.
In order to silence the bogus selinux denial, resolution is skipped for
permitted paths.
Note that the resolution is not strictly required especially for
Treble-ized devices where permitted paths are already canonicalized (i.e
/vendor isn't a symlink to /system/vendor).
Bug: 65843095
Test: no selinux denial on /vendor/app, /vendor/framework, etc. while
booting.

(cherry picked from commit 527757e16b)
Currently, multiple namespaces does not support ASAN mode where some
symbols should be intercepted via LD_PRELOAD; LD_PRELOADed libs are not
preloaded into the linked namespaces other than the default namespace.
Until we fix the problem, we temporarily disable ld.config.txt in ASAN
mode.

This library is used by a number of different libraries in the system.
Make it easy for platform libraries to use this library and create
an actual exported include file.
Change the names of the functions to reflect the new name of the library.
Run clang_format on the async_safe_log.cpp file since the formatting is
all over the place.

Depending on how ld.config.txt is configured, there can be multiple
built-in namespaces created by the linker from the beginning of a
process. android_get_exported_namespace is a platform only API for
getting a handle (android_namespace_t*) to one of the built-in namespaces
with given name. The returned namespace can then be given to
android_dlopen_ext in order to explicitly specify the target namespace
where the library is searched and loaded from.
Note that this function only returns 'exported' namespaces created via
ld.config.txt file. In order to export a namespace, the visible property
should be set to true:
namespace.<name>.visible = true
Namespaces are hidden by default. Hidden namespaces and namespaces
that are created programmatically, notably 'classloader-namespace',
aren't returned by this function.
Bug: 36851137
Test: confirmed that namespaces created with ld.config.txt is retrieved.
Test: linker-unit-tests passes

This change allows customization of default namespace
configuration for different executables. It also enables
target_sdk_version setup for binaries (note that this
option should explicitly be enabled in ld.config.txt).
