(full-disk: no partitions)
In Android, Vold recognizes a USB drive having a full-disk file system
and mounts it properly, but when the drive is removed from system Vold
won't unmount the device. This is because Vold only unmounts partitions.
For a FAT32 USB drive (with partitions), kernel will create two devices:
sda (disk device) and sda1 (partition device). When the drive is removed,
Vold will receive two netlink events: one for partition remove (sda1)
and one for disk remove (sda). The unmount occurs only when partition
remove event is received.
For a full-disk FS USB drive, kernel will only create one device: sda
(disk device). When the drive is removed, Vold will only receive one
netlink event for disk remove (sda) and it won't unmount the device.
This patch will verify if there is a currently mounted device when disk
remove event is received and will perform unmount, to properly unmount
the device.

Add support for the storage with non-sequential partition index
Ex: if using extended partition, the index of the partition will be greater than 5

Switching the kernel to the new sysfs layout (unselecting
CONFIG_SYSFS_DEPRECATED) complicates VolD block device recognition.
The uevents are reporting full specific paths, such as:
/devices/pci0000:0e/0000:0e:18.0/mmc_host/mmc0/mmc0:1234/block/mmcblk0
Because the full device path may contain variable IDs (in this MMC
case "1234") using full path entries in fstab does not work. Android
supports partial matches but only as a prefix at the beginning of the
path.
This patch adds support for matching shell wildcard patterns via
fnmatch(). The prefix matching rule is preserved, but if it is
detected a warning is issued.

When physical devices are unsafely removed, unmountAllAsecsInDir()
fails to find any ASECs, and leaves them all mounted, preventing the
rest of volume from going down.
Now we examine all ASEC containers, and remove when on external
storage, or when the storage media is no longer found.

We now run an sdcard fuse daemon on top of a physical SD card.
Add support for that.

The MAX_PARTS define is not used anywhere in the source code and as
the MAX_PARTITIONS constant was introduced at the same time and used
to hold the same value it's most likely just a remainder from the
development of the partition support code.

Add the force_and_revert option to the unmount command which will force
the unmount, and revert a crypto mapping. This is used during factory
reset so that when the internal sdcard volume is formatted, it formats
the raw device, not the encrypted mapping.

Add support for keeping the keys in a separate file on another partition,
for devices with no space reserved for a footer after the userdata filesystem.
Add support for encrypting the volumes managed by vold, if they meet certain
criteria, namely being marked as nonremovable and encryptable in vold.fstab.
A bit of trickiness is required to keep vold happy.

Only share a single partition via UMS if a specific partition
is specified in vold.fstab (rather than "auto")
Do not fail to reformat if MBR cannot be found.

There's a possibility that if something were messed up a call to
NetlinkEvent::findParam could return a NULL. Passing NULL as the
argument into atoi() would cause a null pointer dereference.
