Although stdout and stderr are both redirected to log file with no
buffering, we are seeing some outputs are mixed in random order.
This is because ui_print commands from the updater are passed to the
recovery binary via a pipe, which may interleave with other outputs
that go to stderr directly.
In recovery, adding ui::PrintOnScreenOnly() function to handle
ui_print command, which skips printing to stdout. Meanwhile, updater
prints the contents to stderr in addition to piping them to recovery.

Calling flush_libtar_buffer would inadvertantly set buffer_status
when no buffer is currently allocated. Later when we called
free_libtar_buffer, this would attempt to free the write_buffer
and cause a crash. This patch checks the value of buffer_status in
flush_libtar_buffer to prevent us from freeing the buffer when it
is not necessary.

LoadResources should only decide on the resource type,
everything else is handled by the resources themselves.

Otherwise, recovery log gets filled up with
"I:Cannot find file /sys/class/thermal/thermal_zone0/temp"
This also fixes build warnings due to duplicate definition of TW_NO_CPU_TEMP.

When it reboots into recovery for a factory reset, it still needs to
write the uncrypt status (-1) to the pipe.

fgets reads up to one byte less than size then with \0 at the end
adding \n after \0 is useless too

In the block updater, if BLKDISCARD fails, the error is silently
ignored and some of the blocks may not be erased. This means the
target partition will have inconsistent contents.
If the ioctl fails, return an error and abort the update.

(cherry picked from commit cc2428c818)
Failures are seen on devices with
Linux 3.10. And they are mainly due to this change:

The blocks reserved in this change is not the same thing as what we
think are reserved for common usage of root user. And this part is
included in free blocks but not in available blocks.

uncrypt needs to be triggered to prepare the OTA package before
rebooting into the recovery. Separate uncrypt into two modes. In
mode 1, it uncrypts the OTA package, but will not reboot the
device. In mode 2, it wipes the /misc partition and reboots.
Needs matching changes in frameworks/base, system/core and
external/sepolicy to work properly.

Note: Only works on ext2/3/4 partitions. Only tested on ext4.
We can use this in some cases to resize the data partition if an
incorrect fstab caused recovery to not reserve the 16KB for a
crypto footer.
Sometimes the BoardConfig for a custom ROM does not have the
correct size for the system partition and if the ROM flashes a
raw system image, that image will not take up the full block
device. Running resize2fs can fix the size and may allow more
room in the system partition for customizations like busybox or
a larger gapps package.
Sometimes flashing a factory image may flash userdata with an
image with a file system that does not take up the full size of
the block device (e.g. factory images for the Nexus 6 will flash
userdata with a ~24GB userdata image, wasting ~30GB of space).
Using resize2fs we can easily fix this issue without having to do
a full format data.
