This is the first in a series of changes that are designed to
introduce better support for dynamic block devices.
It starts by defining a new Volume object which represents a storage
endpoint that knows how to mount, unmount, and format itself. This
could be a filesystem directly on a partition, or it could be an
emulated FUSE filesystem, an ASEC, or an OBB.
These new volumes can be "stacked" so that unmounting a volume will
also unmount any volumes stacked above it. Volumes that provide
shared storage can also be asked to present themselves (through bind
mounts) into user-specific mount areas.
This change also adds a Disk class which is created based on block
kernel netlink events. Instead of waiting for partition events from
the kernel, it uses gptfdisk to read partition details and creates
the relevant Volume objects.

open(O_DIRECTORY) returns an error if the open attempt
is against anything other than a directory. This basically
duplicates the check that the stat() call was trying to do.
Eliminate the unnecessary stat() call and use O_DIRECTORY
instead.

If fstrim thread creation or detachment is failed, wakelock can be leaked.
So move wakelock acquire to do_fstrim_filesystems function

This is to accomodate the new keymaster1_device_t, which has an entirely
different interface.
Soon I'll provide a libkeymaster which provides a unified (and nicer)
interface for dealing with both v0 and v1 keymaster implementations
using a v1 keymaster API. For now this change is just so that vold will
build and run.

Changing the device lock (even from swipe to none) will cause the
master key to be re-encrypted.
If at that point keymaster fails (e.g. due to an incompatible keymaster update)
cryptfs will write back the now-incomplete crypto metadata.
Upon next reboot, userdata can't be decrypted.
Now we don't bother writing on keymaster failure.

This reverts commit 6a69cfc411.
The original fix seems to have led to boot failures in QA. Rather than
risk shipping, revert the change. Bug 18764230 reopened.

Don't use faccessat(AT_SYMLINK_NOFOLLOW). In Android, AT_SYMLINK_NOFOLLOW
is ignored. In glibc, it returns counter intuitive results when a
symbolic link is encountered, returning true all the time even though
an open(O_NOFOLLOW) will eventually fail.
Instead, stat the file and check to see if it's a regular file,
not a directory or symlink or some other weirdness.
In addition, fix a bug where isAsecInDirectory would return
true ("-1") if the asec directory didn't exist. It should return
false.

The strncpy operation does not write a 0 termination
if the name is larger than the target buffer.
Ensure that zero termination is always written using
safe strlcpy function.

Using lseek on 64-bit offset parameter caused failure
to write persistent data in crypto footer.
Changed calls to use lseek64 instead.

The structure crypt_persist_data was allocated,
but never freed.
Added free of allocated memory in normal and
error case.
