This patch preserves the following parameter values:
* Foreground BFQ weight: 100
* Foreground CFQ group_idle: 0
* Foreground CFQ weight: 1000
* Background BFQ weight: 10
* Background CFQ group_idle: 0
* Background CFQ weight: 200
The foreground BFQ weight in task_profiles.json is the default BFQ
weight. From
https://www.kernel.org/doc/Documentation/block/bfq-iosched.txt:
"weight (namely blkio.bfq.weight or io.bfq-weight): the weight of the
group inside its parent. Available values: 1..10000 (default 100). The
linear mapping between ioprio and weights, described at the beginning
of the tunable section, is still valid, but all weights higher than
IOPRIO_BE_NR*10 are mapped to ioprio 0."
Bug: 213617178
Test: Booted Android in Cuttlefish and ran the following test:
Test: adb -e shell cat /sys/fs/cgroup/*/*/io.bfq.weight | sort | uniq -c
Test: 22 default 10
Test: 98 default 100

The "vold.post_fs_data_done" system property was only used by FDE, which
is no longer supported, and this code was commented out anyway.

* changes:
Init: add dev.mnt.blk.bootdevice to access device sysfs
init: mount_handler: detect main block device more reliably
init.rc: use /sys/class/block instead of /sys/devices/virtual/block
This patch adds a new property, 'dev.mnt.root.<mount_point>', which provides,
for example of /data,
1. dm-N
dev.mnt.dev.data = dm-N
dev.mnt.blk.data = sdaN or mmcblk0pN
dev.mnt.rootdisk.data = sda or mmcblk0
2. sdaN or mmcblk0pN
dev.mnt.dev.data = sdaN or mmcblk0pN
dev.mnt.blk.data = sdaN or mmcblk0pN
dev.mnt.rootdisk.data = sda or mmcblk0

/sys/class/block covers all of dm-[0-9], sd[a-z], mmcblk[0-9].
Use it instead of /sys/devices/virtual/block, which only covers dm
devices.
This allows f2fs tunings to be applied more reliably regardless of
how the userdata partition is set up.
Do note that while everything under /sys/devices/virtual/block are
expected to have correct SELinux labels by AOSP, some under
/sys/class/block are not as it's symlinked to platform-specific paths,
and it is up to the vendors to label them correctly.
Test: Confirm entries under /dev/sys aren't dangling and cp_interval,
gc_urgent_sleep_time, iostat_enable and discard_max_bytes are
all set up properly under FBE, FDE and unencrypted.

The clang prebuilts now provide a single module with per-architecture
variants instead of a module per architecture, which means the module
name doesn't match the installed file name. Use the file names

In targets that do not include a zygote binary, attempting to start the
zygote service will result in repeated service restarts. Avoid this by
providing a way for targets to opt out of declaring a zygote service.
The fvp_mini target does not have a zygote, so apply this opt-out to
that target.
Relanding after fixing breakage on an internal branch.
