Some of the pkg specific dirs could be created by zygote
and vold in parallel, so ignore any EEXIST errors while
creating these dirs.

Update vold to only create package sandboxes and not do any bind mounts.
After zygote forks, all the necessary bind mounts will be setup for
the process.

From man 2 umount:
MNT_DETACH (since Linux 2.4.11)
Perform a lazy unmount: make the mount point unavailable for new
accesses, immediately disconnect the filesystem and all filesystems
mounted below it from each other and from the mount table, and
actually perform the unmount when the mount point ceases to be busy.
So we don't need to unmount the filesystems under it one by one.

Don't duplicate what's already in unique_fd.h
Also, code that tries to handle weird stdout condition won't work
because of cloexec; just don't try that.
My tests:
- Ensure Marlin device boots and vold_prepare_subdirs is called
successfully
- Try adb shell sm set-virtual-disk true, see that eg sgdisk output is
logged.

Do our own fork/exec rather than using a library. This leads to
many improvements:
- unite the output recording path with the other path
- never concatenate arguments with spaces
- never use the shell
- move setexeccon after fork, so we don't need to take the lock
- general code refactor while we're there
My tests:
- Ensure Marlin device boots and vold_prepare_subdirs is called
successfully
- Try adb shell sm set-virtual-disk true, see that eg sgdisk output is
logged.

- unlock a user's de and ce directory;
- connect to a OTG storage device or a sdcard and ensure the mount logic be successful

Ensure the device exists before create_crypto_blk_dev returns.

- Also update vold to create sandboxes for secondary storage devices.
- Since bind mounts are created in the process specific namespaces, we
don't need /mnt/storage anymore which we were using it to prevent
some bind mounts from propagating onto /mnt/runtime/write.
- Create bind mounts for {media,obb} dirs similar to data dir in
per process namespace.
- Also fix a bug where we are not passing correct packages to vold when
a new user starts.

This will allow adding lots of verbose logs which can be enabled
only during local testing/debugging. Update the existing verbose

For devices shipped before Android P nothing changes, data
is stored under /data/system/users/<user-id>/fpdata/...
Devices shipped from now on will instead store
fingerprint data under /data/vendor_de/<user-id>/fpdata.
Support for /data/vendor_de and /data/vendor_ce has been added to vold.

Moves away from crufty char* operations to std::string utility
methods, including android::base methods for splitting/parsing.
Rewrite of how Process handles scanning procfs for filesystem
references; now uses fts(3) for more sane traversal.
Replace sscanf() with new FindValue() method, also has unit tests.
Remove some unused methods. Switch almost everyone over to using
modern logging library.
