We rename our 'buf' in the inner scope to avoid confusion with
the 'buf' in the outer scope which is used immediately after
exiting the inner scope.

We have a char buffer on the stack, which we then cast to a
struct, and then proceed to access elements in the struct.
This is not safe across all platforms, as some platforms
may require a certain alignment for members of the struct.
We fix this by assuring an appropriate alignment for our
char buffer.
We also use C++ casting, and rename our buffer to differenciate
it from the other 'buffer' variable in this function.

We make some of the C++ member functions 'const', to reflect how
they (don't) affect the state of the class.

std::remove will only move the matching items to the end, there
should be an erase call after that to actually get rid of those
items from the container.

When an app is started, it's mountmode is dependent on
OP_REQUEST_INSTALL_PACKAGES. If user changes the appop grant of an app,
we need to update the mounts of any processes running in that app.

This adds the ability to upgrade a key and retain the
old one for rollback purposes. We delete the old key
if we boot successfully and delete the new key if we
do not.

We add the property ro.crypto.fde_sector_size to allow devices
to pass the "sector_size:<size>" argument to dm-crypt in the kernel.
We also pass "iv_large_sectors" when setting the sector size.
Using 4096-byte sectors rather than the default of 512 improves
dm-crypt performance, especially when the Adiantum encryption mode
is used.

Adiantum is a crypto method Android is supporting for devices
which don't have AES CPU instructions. See the paper
"Adiantum: length-preserving encryption for entry-level processors"
(https://eprint.iacr.org/2018/720.pdf) for more details.
We add Adiantum to our list of supported crypto types.

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.

persist_get_max_entries() is supposed to return an unsigned integer as the
maximum number of entries but it also wrongly returns "-1" as an error
condition. Also fix an issue where an unsigned subtraction in this routine
could lead to integer underflow.
