Allow the use of a custom Android DT directory

On platforms that use ACPI instead of Device Tree (DT), such as
Ranchu x86/x86_64, /proc/device-tree/firmware/android/ does not
exist. As a result, Android O is unable to mount /system, etc.
at the first stage of init:

init: First stage mount skipped (missing/incompatible fstab in
device tree)

Those platforms may create another directory that mimics the layout
of the standard DT directory in procfs, and store early mount
configuration there. E.g., Ranchu x86/x86_64 creates one in sysfs
using information encoded in the ACPI tables:

https://android-review.googlesource.com/442472
https://android-review.googlesource.com/443432
https://android-review.googlesource.com/442393
https://android-review.googlesource.com/442395

Therefore, instead of hardcoding the Android DT path, load it from
the kernel command line using a new Android-specific property key
("androidboot.android_dt_dir"). If no such property exists, fall
back to the standard procfs path (so no change is needed for DT-
aware platforms).

Note that init/ and fs_mgr/ each have their own copy of the Android
DT path, because they do not share any global state. A future CL
should remove the duplication by refactoring.

With this CL as well as the above ones, the said warning is gone,
but early mount fails. That is a separate bug, though, and will be
addressed by another CL.

Test: Boot patched sdk_phone_x86-userdebug system image with patched
Goldfish 3.18 x86 kernel in patched Android Emulator, verify
the "init: First stage mount skipped" warning no longer shows
in dmesg.

healthd: notify listeners using local copy of list, drop lock

Binder currently may service an incoming oneway transaction whenever
an outbound oneway call is made (if there is already a pending
incoming oneway call waiting). The unexpected nested method call
blocks forever on a recursive mutex acquire because healthd is single-
threaded. The binder behavior is considered a bug and may change in
the future. For now, work around this in healthd.

Make a local copy of the listeners list, then drop the lock and
perform the outbound calls on the local copy of the list.

ld-config: Export android.hidl.memory@1.0-impl

This commit exports android.hidl.memory@1.0-impl.so from default linker
namespace to vndk (VNDK-SP) linker namespace. This fixes
libhidlmemory.so failure.

Note: Exposing android.hidl.memory@1.0-impl.so from default linker
namespace to vndk (VNDK-SP) linker namespace shall be fine because its
APIs are frozen and won't be changed in the future.

Note: android.hidl.memory@1.0-impl.so is NOT exported to sphal linker
namespace.

This commit adds libhidlmemory.so and android.hidl.memory@1.0.so to the
exported libs of the `vndk` linker namespace (aka. VNDK-SP). This is
necessary because some vendors' GLES implementation uses
libhidlmemory.so. Check http://b/35107583#comment15 for the context.

init: poll in first stage mount if required devices are not found

First stage mount in init currently attempts to regenerate uevents for
specific devices to create the corresponding dev nodes. However, this
is racy as first stage mount happens early in the boot process and
it's possible that some of these devices have not yet been created by
the kernel.

To fix this issue, init will poll on the uevent socket for up to 10
seconds waiting for the kernel to create the required device. It will
return false and panic if this 10 second timeout passes.

Note that the same uevent socket is used in the uevent regeneration
and the polling code, so there is no race if the device is created
after the uevent regeneration and before polling starts; the first
poll will pick up the device.

ueventd: remove PlatformDeviceList

In order to create symlinks for USB and block devices, the path for
their parent platform device must be known.

Previously, ueventd would save each platform device that it encounters
to a list and query this list when creating the symlinks. That,
however, is racy because the uevent socket does not differentiate
uevents from device_init() and uevents sent by the kernel when
probing a device first the first time. The below scenario is the
faulty case:

1) Kernel probes parent platform device for a block device
2) ueventd calls device_init() and starts processing uevents
3) Kernel probes block device and sends its uevents
4) ueventd picks up the block device uevent during its uevent processing,
without yet regenerating the platform device uevent, causing improper
symlinks to be created.

This change stops storing the platform devices in a list, and instead
traverses up the directory structure for each USB or block device
until it reaches a platform device, defined as one whose subsystem is
the platform bus. This fixes the race and simplifies the ueventd
code.
