We will convert a -16384 to 16384 if needed because mkfs.f2fs
does not like negative numbers like make_ext4fs does. Also enable
trim by default on f2fs.

This will stop the iteration of the partition objects, kill the
current twrpTar thread and remove the backup directory.
Implement TWAtomicInt class to give us a wrapper that automatically
uses mutexes before the read and write to help ensure that the
reads and writes will be atomic based on documentation.

With 5.0 L, we decrypt automatically if the default_password is
used. Non datamedia devices do not get the format data button so
they cannot wipe encryption off the device. This patch add a wipe
encryption button where the format data button would normally be
located on the Wipe page.
This patch also attempts to remove / delete the dm-crypt block
device before formatting.

Implement a pipe between TWRP and MTP to allow TWRP to tell MTP
to remove storage partitions as they become unavailable (e.g.
during a wipe, unmount, etc) instead of disabling MTP completely.
This includes some fixes and improvements in destructors to
properly remove / delete various items. This also means that we
will not be toggling adb off and on quite as often.
I do not like that we had to add another thread, but we were
unable to use select() on the mtp_usb character device because
this device does not support polling. Select always returned
indicating that the mtp file descriptor was ready to be read and
the resulting read would block. The read block prevented us from
being able to include reading of the pipe between TWRP and MTP in
the main MTP thread.
We might want to add a return pipe letting TWRP know if the
removal of the storage device was successful, but I am not sure
how we want to implement this. It would invovle timeouts in both
TWRP and MTP to ensure that we returned a failure indicator in a
timely manner to TWRP and prevent deleting the storage device in
the case of a failure. Right now we make no attempt to ensure that
an MTP operation is underway like a large file transfer, but we
were not doing anything like this in the past. In some respects we
have limited control over what happens. If the user installs a
zip that unmounts a storage partition, we will not know about the
change in storage status anyway. Regular Android does not have
these troubles because partitions rarely get unmounted like in
recovery. At some point, we have to hold the user accountable for
performing actions that may remove a storage partition while they
are using MTP anyway.
Ideally we do not want to toggle the USB IDs and thus toggle adb
off and on during early boot, but I am not sure what the best way
to handle that at this time.

Files and folders that we create during backups, copy log, or MTP
operations often do not have the proper uid/gid/contexts assigned.
We will attempt to read the proper contexts from the settings
storage path and assign those same contexts to any files or dirs
that we create.

This is mostly kang from AOSP resources.c for loading png files

support for alpha blended png files.

Trim cryptfs.c to remove functions that TWRP does not use for
decrypt and remove the need for libfs_mgr from cryptfs.c by
passing some items to cryptfs.c from the partition manager.
Add support for new fstab flags:
encryptable and forceencrypt=/path/to/cryptokey
For example:
flags=forceencrypt=/dev/block/platform/sdhci-tegra.3/by-name/MD1
Note that "footer" is the default, so you do not need to set this
flag on devices that use the footer for the crypto key.
Also add mounttodecrypt if you need to mount a partition during
the decrypt cycle for firmware of proprietary libs.
Clean up decrypt and only support one version
Android 5.0 lollipop decrypt should be backwards compatible with
older versions so we will only support one version, 1.3 that came
with 5.0 lollipop.
Remove support for Samsung TouchWiz decrypt. It does not work with
the latest versions of Samsung encryption anyway and it has not
been updated to work with any AOSP decryption higher than 1.1

Kang in cryptfs.c and cryptfs.h from vold.
Use TW_INCLUDE_L_CRYPTO := true to enable.
Ramdisk must contain the normal fstab file in the root in the
usual format of:
fstab.{ro.hardware}
For examble for Nexus 5:
fstab.hammerhead
Or on many Qualcomm devices:
fstab.qcom
Tested against Android 5.0 lollipop on Nexus 7 2012 grouper. Not
sure if or how this will work when we are dealing with a device
with a hardware keystore. Long term we need to add a GUI element
to allow entering a pattern. For now you can decrypt a pattern
unlock by converting the dots to numbers in the following format:
123
456
789
So an upper-case L would translate to 14789 as a password entered
on the keyboard.

Some devices (jewel, m8) have .android_secure at a non-standard
location. Allow a different partition to be specified as the home of
.android_secure using the fstab flag 'andsec'.
Using the /data/media variant of jewel as an example, recovery.fstab or
twrp.fstab could be edited like follows:
/external_sd vfat /dev/block/mmcblk1p1 flags=display="MicroSD";andsec
Note, this is NOT a method to move .android_secure in your ROM. Your ROM
must already write to this alternative location.
