older devices.

There are cases such as non 4KB aligned buffers which break writes on
file descriptors opened with O_DIRECT. Flashing functions need more
control over the file descriptor, which is not achievable easily by
having only a file descriptor passed. This CL modifies the logic to pass
the PartitionHandle in place of the file descriptor during flashing.

There have been two bugs where people use !metadata_encryption.empty()
to check whether metadata encryption is enabled. It should actually be
!metadata_key_dir.empty(), since 'metadata_encryption' is the encryption
options, which can be empty if the defaults are sufficient.
Rename the field in FstabEntry appropriately.
To avoid breaking fstab files, don't rename the flag in the fstab file
itself. So, now the fstab flags map to FstabEntry fields as follows:
keydirectory => metadata_key_dir
metadata_encryption => metadata_encryption_options

Some but not all memcg v1 attributes exist in the v2 hierarchy. The
following information comes from Shakeel Butt and Kamil Yurtsever,

and v2 hierarchies. Also add those memcg attributes that are used in
lmkd.

Cgroup attributes like io.weight or io.bfq.weight only exist if the
corresponding I/O scheduler has been loaded. Hence add support for
ignoring failures to write to a cgroup attribute that does not exist.

Test: This patch has been tested in combination with patch "Migrate the blkio controller to the cgroup v2 hierarchy".

This adds two new diagnostics. First, signalfd reads are now non-blocking. If the read takes more than 10 seconds, we log an error.
Second, init now wakes up from epoll() every 10 seconds. If it waits on an "exec" command for more than 10 seconds, it logs an error.
This change will be reverted as soon as we get feedback.

Cgroup attributes are set from three different contexts:
(1) From the process that creates the cgroup directories. These
processes are /system/bin/init, zygote and zygote64.
(2) From the created process. Some but not all created processes have
user ID and/or group ID 'system'.
(3) The system_server process modifies certain cgroup attributes from
other processes.
Allow all processes from the system group, including system_server, to
modify cgroup attributes from other processes. As one can see in
init.rc, that file includes commands for granting the system group
write permission for blkcg attributes. See also
