We are now conditionally compiling init binaries & libinit for
Microdroid (adding -DMICRODROID=1 cflag), so instead of checking for the
presence of the /system/etc/selinux/microdroid_precompiled_sepolicy we
can check if the code is compiled for Microdroid.
In a follow-up changes we can split the sepolicy loading logic into 2
separate headers (one for Android and one for Microdroid) and include
the necessary one depending on the target we compile for.

This is likely waiting for the Java garbage collector to run,
and due to the lockless implementation of BinderProxyNativeData
and BpBinder, it's very difficult to efficiently force this

The initial logic for adding this in was incorrect. This changed had
allowed us to do fastboot flash dts dt.img on command line. But really
we should enforce that we pass in the path to the image. This change was
added so the command line tool with resemble fastboot-info format which
will support flash dts dt.img (situation where image name and partition
name don't match).

Test: build com.android.virt APEX
Change-Id: Ib9af0cfcdf06c70fc39e6e6ac8ef07bb69982969
Previously, libdm ensured that uevent will be generated when a dm device
is deleted. However, there actually are cases where uevent can't be
expected; for example, if an empty dm device is created, but then gets
deleted without being activated, then there should be no uevent upon
deleting because there actually is nothing to remove from /dev. (dm
device gets added to /dev only if it is activated).
Actually such a case exists in apexd. As a performance optimization, it
proactively creates empty dm devices for all APEXes it scanns. But
some of them don't ever get activated if the APEX is already in a
dm-verity protected block device (i.e. the pre-instaled APEX is the
latest one). In that cases, the empty dm devices are deleted at the end
of the boot process as a clean up.
The libdm triggered error during the clean up, because there was no
uevent generated for the empty dm devices. This has triggered a lot of
false alarms to the apex team.
This CL fixes this by ensuring uevent only for activate dm devices. If
the dm device doesn't show up in /dev, we just delete the in-kernel
object and don't expect it to generate uevent for it - which actually is
the kernel's behavior.

When IOServiceGetMatchingServices returns an invalid

to prevent being stuck in the reset loop forever.
This should be fine as the open_device() call in the
