Public SdCard Volumes are mounted only for user 0
(foreground user). This gives ENONT if the cloned
user tries to access the files in SdCard with
paths like "/storage/AB02-G212/DCIM/"
This change adds SdCard Volume mnt under
/mnt/usr/<cloned-user>/ which allows cloned apps
access to SdCard via direct file paths.

StorageStatsManager.getTotalBytes currently takes the size of /data and
rounds up to known probable sizes to guess the size of internal storage.
This is not always correct.
Instead, find the device /data is on and get the size of that device.
This should give a more accurate answer.

This reverts commit 78f806198f.
There is no code that reads this system property, logcat already shows
whether the FS keyring is being used, and all devices launching with
Android 11 and later are guaranteed to use the FS keyring anyway.

vold_prepare_subdirs should create apexdata directories for each APEX.
Previously, it gets the list by scanning /apex directory. However,
vold/vold_prepare_subdirs run in the bootstrap mount namespace, they can
see only bootstrap apexes in /apex. The reason why it worked was that
unintended side effects of how we managed /apex directory for both mount
namespace.
Instead, since apexdata directories are already populated by init in
/data/misc/apexdata, we can use that directory for the same purpose.

In this change, the logic to get the list of apexes is replaced with
the query to apexservice, which is the source of truth. This dedups
the manual scanning of /apex for the apex list, which should be
internal to apexd. (Note how vold_prepare_subdirs filtered out
directories with "@" character).
This also makes vold_prepare_subdirs immune to the upcoming changes:
/apex directory containing only bootstrap APEXes in the bootstrap NS.
Until now, getting the list of apexes by scanning /apex was okay
because of the accidental fact that /apex directory has directories
for all the apexes, not only bootstrap apexes.

Newer versions of libc++ check that an allocator can be rebound to the
same element type. We need to add a rebind member to ZeroingAllocator
to fix this compiler error:
prebuilts/clang/host/linux-x86/clang-r498229/include/c++/v1/vector:376:19: error: static assertion failed due to requirement 'is_same<android::vold::ZeroingAllocator, std::allocator<char>>::value': [allocator.requirements] states that rebinding an allocator to the same type should result in the original allocator
static_assert(is_same<allocator_type, __rebind_alloc<__alloc_traits, value_type> >::value,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It likely doesn't matter in practice because this allocator is only
used with std::vector, which probably doesn't use allocator rebinding,
because it won't allocate an internal node type (e.g. unlike std::map,
std::list, etc).
Alternatively, ZeroingAllocator could be changed to a
ZeroingAllocator<T> that can zero arbitrary types, but it doesn't seem
necessary currently, and types other than char wouldn't be used.

When a volume is ejected from a user but not removed from the device
and mounted again by calling StorageManager#mount, the volume is
mounted for the user from which it was last ejected. This causes the
path of the mounted volume to be inaccessible to the current user.
Whenever StorageManager#mount is called, check if the
VolumeInfo#mountUserId is same as the current userId maintained by
StorageManagerService, if it is not, change the mountUserId for the
Volume to the current userId known to StorageManagerService if it
is not the primary volume and the volume is visible.
This change also fixes a bug where the volumes are unmounted for the
wrong user which causes StorageSessionController go out of sync
which would cause errors during mounting the volumes again as it
maintains sessions per user. The bug also caused volume event
broadcasts to be sent to wrong user handles. To solve the issue
add an extra paramter in IVoldListener#onVolumeStateChanged for userId
which will update the copy which is used for informing
StorageSessionController and also for sending broadcasts.
Test: Perform the following steps:
1. Format SD Card as portable storage in system user.
2. Eject the SD Card from Storage Settings.
3. Switch to a non-system user
4. Mount the SD Card again.
5. Check that the Storage Summary is shown correctly instead
of 0B out of 0B.
Also, checked from the logs the volume state broadcasts are sent to
the correct user handles.
