This CL adds three GSI keys, to allow booting a GSI with AVB
to enable dm-verity.
https://android.googlesource.com/platform/external/avb/
The keys for R and S GSI is to allow a device boots a new
version of GSI in a Treble-compatible manner.

Android sets /proc/sys/vm/dirty_expire_centisecs to 200, so f2fs

Since there has never been a time that a sequential search has been
necessary, simply remove the sequential code and allow the DwarfEhFrame
object to be used in that case. If this does come up regularly, I'm not
sure that it wouldn't be more performant to use the DwarfEhFrame object
regardless.

Having shared host libraries allows libraries depending on these to use
'shared_libs' for these. This simplifies configurations since these
libraries don't have to specify 'shared_libs' on all non-host targets.

This catches a common mistake where client code checks for errors using
the common idiom that works for std::iostream and other file-like

SetupCgroups is called by init process during early-init stage and is not
supposed to be called again by anyone else. Ensure that the caller is the
init process, make sure cgroup.rc file is written only one time, keep the
file descriptor to cgroup.rc file open by the init process to ensure all
its further mappings stay valid even if the file is deleted.

On marlin, dev.mnt.blk.root is empty. Issue is shared for all
devices that are system-as-root.
/dev/root /proc/mounts entry exists before the associated block device
is instantiated by ueventd. As a result when the device shows up the
root mount is updated late when the next mount inotify trigger occurs,
delay which we will accept. But the property entries are added before
removed in the loop which causes the ultimate property entry for root
to report empty. Add /dev/block/dm-0, remove /dev/root, for property
dev.mnt.blk.root.
Fix is to change to Remove before Adding. Remove /dev/root, then add
/dev/block/dm-0.
On system-as-root as well, can not just use fstab. Determine if a
dm-verity reference is wrapped around system and use that instead.
Add some additional filtration of loop and APEX mounts to reduce
property noise.
Fix issue with creating the std:string line holder from getline(3).

Occasionally, after we open the functionfs endpoint and write our
descriptors to it, we end up in a state where we never receive any
events from ep0, presumably due to a race against some other part of
the system, since adding sleeps reduces the likelihood. Add an
(arbitrarily chosen) timeout for the initial FUNCTIONFS_BIND we read,
and retry on failure.

Update the powerof2 macro to one that is integer overflow safe.
This definition is the same one used by bionic, but cleaned up using
clang_format.

Occasionally we see cases when 40ms polling is still too conservative.
Change to 10ms polling period. Since the polling happens only after PSI
signal and continues for 1sec this should not affect system performance.

Call android_get_control_file on last_kmsg files if the file
descriptor is provided by init.
Also, uses base::Read(File|Fd)ToString functions to read the
files (because load_file doesn't support fd arguments).

* changes:
libbase: realpath is wrapped with TEMP_FAILURE_RETRY
liblp: Replace open with GetControlFileOrOpen
init: expand prop in 'file'
libcutils: android_get_control_file uses realpath.
If we fail to submit writes for some reason (e.g. the USB cable was
unplugged), another thread that's waiting on the write mutex can enter
SubmitWrites and attempt to resubmit the writes that we already failed
to submit, leading to a failed assertion of !IoBlock::pending.
Increment writes_submitted_ before actually calling io_submit, so we
skip over these writes and fall through to exit.
