SoC vendors and ODMs need a way to run different init scripts under
different boot modes. This patch adds a new ro.boot.init_rc kernel
cmdline argument to support this.
This patch also changes late-init trigger. Now late-init is only
triggered in "normal" boot (where boot mode is not specified). This is
to make AOSP init.rc re-usable in other boot modes as the operations
in late-init are less common.
Bug: 26639863
Test: Tested on bullhead with
androidboot.init_rc = {non-existent .rc file}
and/or
androidboot.init_rc = {none empty string}
both of which lead to expected boot failures.

This is a cherry-pick of internal commit:
f611291688 which was a revert of a
revert, specifically a revert of commit:
c8f026fc9c.
The above revert was meant only for AOSP, since the kernel prebuilts
were not yet available there. The revert was reverted internally so
that internal builds, which have the appropriate kernel prebuilts,
operated properly.
The very first commit was originally done in nougat-dev and cherry-picked
to AOSP, so it was not picked up again when nougat landed in master. Add
it now.

This issue reproduces in the following senario.
1. ("", "") is added to queue;
2. property_triggers_enabled is set to 1;
3. user defined property is triggered, like sys.usb.config=adb;
4. ("sys.usb.config", "adb") is added to queue;
5. main loop interpret ("", "") and queue all current triggers to execution,
so ("sys.usb.config", "adb") is queued for execution for the first time.
6. main loop interpret ("sys.usb.config", "adb"), it is queued for
execution for a second time.
The second time makes ASIT fail.

With this change, init sets a property "init.start" to show the
CLOCK_BOOTTIME time at which init itself started, and for each service
an "init.svc.<name>.start" property to show the CLOCK_BOOTTIME time at
which that service was most recently started.
These times can be used by tools like bootstat to track boot time.
As part of this change, move init over to std::chrono. Also, rather than
make the command-line argument handling more complex, I've switched to
using an environment variable for communication between first- and
second-stage init, and added another environment variable to pass the
start time of the first stage through to the second stage.

bootcharts currently only show root's processes, which isn't very
useful. To investigate and track boot duration issues, we need a way for
init to see all the pids. Add init to GID 3009 (aka AID_READPROC)
Ensure that init's children don't inherit this GID by always clearing
supplementary group IDs on fork.

Right now these two partitions are mounted in the fs stage of the init
process. As a result, many vendor/ODM files needed earlier in the boot
process (e.g., init.<hardware>.rc, fstab.<hardware>.rc,
uevent.<hardware>.rc, SELinux policy files etc) can only live on the root
partition.
To prevent vendors/ODMs from polluting the root partition, this patch makes
it possible to mount the vendor and ODM partitions in the first stage of the
init process. The fstab info of both partitions to be mounted early is
composed from new kernel cmdline arguments android.early.prefix and
android.early.fstab.
For example, with:
android.early.prefix=/sys/devices/1010000.msdc0/mmc_host/mmc0/mmc0:0001/block/mmcblk0/
android.early.fstab=mmcblk0p10+/odm+ext4+ro+verify\nmmcblk0p09+/vendor+ext4+ro+verify
the final fstab string will be:
/sys/devices/1010000.msdc0/mmc_host/mmc0/mmc0:0001/block/mmcblk0/mmcblk0p10 /odm ext4 ro verify
/sys/devices/1010000.msdc0/mmc_host/mmc0/mmc0:0001/block/mmcblk0/mmcblk0p09 /vendor ext4 ro verify
The android.early.prefix is optional. When it is missing, the final fstab
string will be directly converted from android.early.fstab.
This patch also makes sure that the early mounted partitions are dm-verity
enabled so that they are trust worthy to store system files.

Add the following mount options to the /proc filesystem:
hidepid=2,gid=3009
This change blocks /proc access unless you're in group 3009
(aka AID_READPROC).
Please see
https://github.com/torvalds/linux/blob/master/Documentation/filesystems/proc.txt
for documentation on the hidepid option.
hidepid=2 is preferred over hidepid=1 since it leaks less information
and doesn't generate SELinux ptrace denials when trying to access
/proc without being in the proper group.
Add AID_READPROC to processes which need to access /proc entries for
other UIDs.
