Previously, AppFuse is mounted in system_server's mount namespace. This
CL moves the mount location to vold namespace.

It can sometimes take a moment for the dm-device to appear after
creation, causing operations on it such as formatting to fail.
Ensure the device exists before create_crypto_blk_dev returns.
Test: adb sm set-virtual-disk true and format as adoptable.

We support file-based encryption on both ext4 and f2fs now, and the
kernel API is the same. So rename things appropriately in vold:
e4crypt => fscrypt
ext4enc => fscrypt
Ext4Crypt => FsCrypt
EXT4_* => FS_*
ext4_encryption_key => fscrypt_key
Additionally, the common functions shared by 'vold' and 'init' are now
in libfscrypt rather than ext4_utils. So update vold to link to
libfscrypt and include the renamed headers.
Note: there's a chance of 'fscrypt' being confused with the dm-crypt
based encryption code in vold which is called 'cryptfs'. However,
fscrypt is the name used in the kernel for ext4/f2fs/ubifs encryption,
and it's preferable to use the same name in userspace.
Test: built, booted device with f2fs encryption

bionic now has linux/fs.h from the 4.14 kernel, which has the fscrypt
kernel API declarations. Replace the manual declarations in vold,
except for FS_AES_256_XTS_KEY_SIZE which is not available.

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.
