These includes are included transitively by liblog, but not by the VNDK
version of liblog.

By setting vendor_available, the following may become true:
* a prebuilt library from this release may be used at runtime by
in a later releasse (by vendor code compiled against this release).
so this library shouldn't depend on runtime state that may change
in the future.
* this library may be loaded twice into a single process (potentially
an old version and a newer version). The symbols will be isolated
using linker namespaces, but this may break assumptions about 1
library in 1 process (your singletons will run twice).
Background:
This means that these modules may be built and installed twice --
once for the system partition and once for the vendor partition. The
system version will build just like today, and will be used by the
framework components on /system. The vendor version will build
against a reduced set of exports and libraries -- similar to, but
separate from, the NDK. This means that all your dependencies must
also mark vendor_available.
At runtime, /system binaries will load libraries from /system/lib*,
while /vendor binaries will load libraries from /vendor/lib*. There
are some exceptions in both directions -- bionic(libc,etc) and liblog
are always loaded from /system. And SP-HALs (OpenGL, etc) may load
/vendor code into /system processes, but the dependencies of those
libraries will load from /vendor until it reaches a library that's
always on /system. In the SP-HAL case, if both framework and vendor
libraries depend on a library of the same name, both versions will be
loaded, but they will be isolated from each other.
It's possible to compile differently -- reducing your source files,
exporting different include directories, etc. For details see:

None of this is enabled unless the device opts into the system/vendor
split with BOARD_VNDK_VERSION := current.

fs_mgr_update_verity_state() is invoked by 'verity_update_state' in
init.rc. It will then set property "partition.system.verified" and
"partition.vendor.verified" to verify_mode. We should support this for
AVB as well.
Also change the order of static libs in init to fix the build error
after this change:
system/extras/ext4_utils/ext4_crypt.cpp:69: error: undefined reference to 'property_get'

libavb requires verifying AVB metadata on all verified partitions at
once. For example, /vbmeta, /boot, /system and /vendor. We need to
invoke device_init() for those partitions even if we only want to early
mount some of them, like /vendor and /system.
This CL gets all AVB partitions and the early mount partitions from
device tree through "firmware/android/vbmeta" and "firmware/fstab",
respectively. The following is an example to early mount /vendor
partition on bullhead:
firmware {
android {
compatible = "android,firmware";
vbmeta {
compatible = "android,vbmeta";
parts = "boot,system,vendor";
by_name_prefix="/dev/block/platform/soc.0/f9824900.sdhci/by-name"
};
fstab {
compatible = "android,fstab";
vendor {
compatible = "android,vendor";
dev = "/dev/block/platform/soc.0/f9824900.sdhci/by-name/vendor";
type = "ext4";
mnt_flags = "ro,barrier=1,inode_readahead_blks=8";
fsmgr_flags = "wait,avb";
};
};
};
};

These headers are used in headers in libsystem_headers and must be
re-exported.
Test: modules using libsystem_headers don't have to have
libaudio_system_headers include dirs set.
