I thought it was OK to use "using" in a header file so long as it was
inside a "namespace" block, but it just imports symbols from one
namespace into another, so things that shouldn't work do.

Now that vold uses Keystore2 rather than the Keymaster HAL directly, and
also the new version of Keymaster is called "KeyMint" instead, replace
most of the references to Keymaster in vold with Keystore.
(I decided not to include the "2" in most places, as it seemed
unnecessarily precise in most places, and it would be something that
might need to keep being updated. Only Keystore.{cpp,h} really need to
care about the version number.)
I didn't rename many things in cryptfs.cpp, as that file will be going
away soon anyway. I also left "wait_for_keymaster" and "vdc keymaster
earlyBootEnded" as-is for now, as those are referenced outside vold.

* changes:
Don't export storeKey(), and update comments
Always use RenameKeyDir() when moving/renaming key directories
Make RenameKeyDir() use IsSameFile()
storeKey() is no longer used outside KeyStorage.cpp, so make it a static
function. Also fix the documentation for storeKey() (e.g. it's no
longer safe to directly move/rename directories created by storeKey() --
one must use RenameKeyDir() instead).
No functional changes.

Make fixate_user_ce_key() use RenameKeyDir() to rename key directories
so that any deferred commits for these directories are also updated
appropriately.
This fixes a potential lost Keymaster key upgrade if a key were to be
re-wrapped while a user data checkpoint is pending. This isn't a huge
issue as the key will just get upgraded again, but this should be fixed.

Comparing paths is error-prone (e.g. "/foo/bar" vs "/foo//bar"), so
entries in key_dirs_to_commit are compared using inode and device
number. However RenameKeyDir() breaks this rule and compares raw paths.
Avoid this quirk by finding the entry in the list to replace before
doing the rename.
This doesn't fix any known problem, as vold is fairly consistent with
its paths in practice; this is just a robustness improvement.

ensure_subdirectory_unmounted() was ignoring the return value from
umount(), so it wasn't possible to tell whether it succeeded or failed.
Make it log an error message on failure.
Also, there might be cases where ensure_subdirectory_unmounted() fails
initially but would succeed later, e.g. due to files in a subdirectory
mount being open and requiring processes to be killed. To make this
more robust, keep calling ensure_subdirectory_unmounted() before each
attempt of umount("/data").
I'm not sure whether this will actually fix bug 189250652, as it hasn't
been root-caused yet, but this might help.

When a user is removed, vold is deleting the subdirectories of
/data/misc/vold/user_keys/ce/${user_id} but not that directory itself.
This is unexpected, as none of the user's directories should be left
around. Delete it too.

storeKeyAtomically() stores keys in a temp directory before renaming
that directory to the real target directory. However when the key is
stored in the temporary directory, the Keymaster storage key might get
upgraded, and it's possible that the temp directory is scheduled for a
deferred commit. storeKeyAtomically() renames that temp directory, but
doesn't update the list of directories marked for deferred commit.
This patch fixes this by removing the temp directory from the list and
adding the real target directory to that list instead.
This bug was found when trying to switch from using the guest keymint to
using the host remote keymint implementation on cuttlefish
(aosp/1701925). The device triggers this bug (and boots to recovery)
when aosp/1701925 is cherry-picked.
