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

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

This library doesn't actually exist outside of ARC specific branches,
so it will break any ARC product builds.

Only trys to commit if necessary, and reports errors
if commiting fails. RemoveFileIfExists returns true on
success.

Device can't start up after the following steps:
1. set screen lock to PIN/Pattern/Password
2. set screen lock to Swipe/None
3. power down immediately after pressing "YES, REMOVE"
4. reboot
failed log:
Failed to read from /data/misc/vold/user_keys/ce/0/current/keymaster_key_blob

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

StubVolume is a Volume that is maintained by external party such as the
ChromeOS processes in ARC++.

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.
