Android 4.4.4 Release 1
ota: Let devices specify their own recovery-from-boot.p installer

Some devices apply transformations to the installed images, making
the sha1 checksums fail (or, worse, generating invalid images). If
"/system/etc/recovery-transform.sh" exists, run that instead, passing
the expected sizes and checksums as arguments in the form of

recovery-transform.sh <recovery_size> <recovery_sha1> <boot_size> <boot_sha1>

A direct emulation of the standard patcher could look like this, transformations
should be added as needed.

----------------
RECSIZE=$1
RECSHA1=$2
BOOTSIZE=$3
BOOTSHA1=$4

dd if=/dev/block/platform/msm_sdcc.1/by-name/recovery of=$C/recovery.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/boot of=$C/boot.img

if ! applypatch -c EMMC:$C/recovery.img:$RECSIZE:$RECSHA1; then
  log -t recovery "Installing new recovery image"
  applypatch -b /system/etc/recovery-resource.dat EMMC:$C/boot.img:$BOOTSIZE:$BOOTSHA1 EMMC:$C/recovery.img $RECSHA1 $RECSIZE $BOOTSHA1:/system/recovery-from-boot.p || exit 1
else
  log -t recovery "Recovery image already installed"
fi
