Test that:
1) Logs are cleared
2) More logs can be added after clear
3) Well behaving blocking readers stay connected and can read new logs
after clear.
Test: this unit test

Clear() and Prune() return a boolean indicating whether or not their
operations failed because the log buffer was 'busy'. This means that
they return false upon success and true upon failure, which is not
intuitive.
This change inverts their return value to simply be true if they were
successful or false otherwise. It also simplifies the return value of
ChattyLogBuffer::Prune() to true if the requested number of rows have
been pruned or if all rows in the log buffer have been pruned, and
otherwise return false.
Test: logging unit tests
Test: clearing works even under logging pressure

Regardless of whether a system property is "ro." or not, it can be
overridden by build.prop from the more specific partition. i.e.
foo.bar=true in system/build.prop can be overridden by
foo.bar=false in vendor/build.prop. However, the warning message
was referring the overridden property as "ro." causing confusion
when reading the log. Fix it by not mentioning "ro.".

Init starts ueventd in the default mount namespace to support loading
firmware from APEXes.

If the superblock of /data is corrupted, fs_mgr would skip check_fs.
But, e2fsck actually may reference backup superblock to recover
the filesystem. This fix gives fs_mgr second chance to fix corrupted
ext4 /data.

Status() is called with an empty string to handle `fastboot oem`
commands. This currently emits a set of spaces and sets
last_start_time such that the epilog can track the time spent in this
command. Emitting the spaces is problematic however, since it results
in the follow:
$ fastboot oem device-info
(bootloader) Verity mode: false
(bootloader) Device unlocked: true
(bootloader) Device critical unlocked: true
(bootloader) Charger screen enabled: true
OKAY [ 0.000s]
Finished. Total time: 0.000s
If we skip emitting the spaces, then we get the correct result:
$ fastboot oem device-info
(bootloader) Verity mode: false
(bootloader) Device unlocked: true
(bootloader) Device critical unlocked: true
(bootloader) Charger screen enabled: true
OKAY [ 0.001s]
Finished. Total time: 0.001s
There are no other uses of Status() with an empty string, so this
changes won't impact other commands.
Bug: 158310284
Test: fastboot formats this and other commands correctly.

for a first implementation the cgroup v2 freezer controller will be used in a
way similar to cgroup v1, that is a single child group will hold all frozen
processes. Some adjustments are needed for the new structure.
- Add support for cgroup v2 syntax under procfs.
- Separate creation of a directory with ownership/mode changes to allow changes
after mounting the cgroup kernfs root.
- Allow the creation of sub-groups under a cgroup v2 hierarchy.
Bug: 154548692
Test: manually verified that a proper cgroup v2 hierarchy is created and
accessible

Previously, Soong visibility rules did not affect Make modules. Now
these checks have been implemented in:
https://android-review.googlesource.com/c/platform/build/+/1324454
So this fixes the visibility rules to include modules that were
previously using libbacktrace_no_dex.

The same adbd module prebuilt will get used for both user and userdebug
builds in the post-APEX world, so we can't guard functionality with
product variable ifdefs anymore.
The code that was previously compiled out runs before we drop root, so
the increased attack surface essentially consists of an attacker having
control over system properties, and that likely implies that we're
doomed already (either they have filesystem control, or they have code
execution in init).

I neglected to update swapon_all. Trivially copied from umount_all.
