The use of this function, which is a wrapper over libuboot_get_env(),
requires checking if the returned string is NULL.
Manipulations of such string without checking whether it's NULL may lead
to segfault errors.
This was seen during firmware update on a device that didn't have the
'dualboot' variable set.

(cherry picked from commit 8a4484bbd6)
NetworkManager's main library went through a major overhaul in v1.22, changing
the way it interacts with glib among other things. When using a NetworkManager
version equal or newer than v1.22 along with a glib version between 2.63.3 and
2.65, a race condition can happen, randomly causing segmentation faults.
Since Yocto 3.2 uses NetworkManager 1.22.14 and glib 2.64.5, the race condition
is reproducible, but it can be fixed with the patch introduced in this commit.
The patch in question is commit e4a690f5dd959e74b2d6054826f61509892c8aa7 in the
glib git repo.

There are some init packages from the poky layer that remain using only a SysV

In the libubootenv implementation of fw_setenv, multiple variables can be set
in one call. When setting a variable with a space-separated list, the app
interprets the list as new variable/value tuples, for example:
fw_setenv myvar value1 value2 value3
Results in:
myvar=value1
value2=value3
This was causing the encrypted eMMC partition mechanism to break, because the
list of encrypted partitions is stored as a space-separated list in an
environment variable. Avoid this by enclosing the variable argument of
set_uboot_var() with double quotes.

Before using the encrypted partition functionality, users have to manually
install the encryption key in the system. Failing to install said key will
result in errors later on.
Even though the installation isn't a difficult operation from a user's point of
view, the recovery script has the necessary logic to detect cases where a
partition is going to be encrypted with no key installed. Automatically
generate a key in these cases to avoid undesired behavior and to improve the
overall user experience.

If we allow users to manually change the encryption status of the rootfs
partition, we run the risk of wiping it without flashing a proper replacement
image. Because of this, rootfs encryption status should be determined
automatically using information from the update package.

whether to encrypt the rootfs or not.

Previously, TRUSTFENCE_INITRAMFS_IMAGE was the only variable used to configure
rootfs encryption. Now that any partition can be encrypted and the rootfs
encryption still needs to be handled differently, use two variables instead.
* TRUSTFENCE_ENCRYPT_PARTITIONS to control partition encryption in general
* TRUSTFENCE_ENCRYPT_ROOTFS to control rootfs encryption
As with most trustfence functionality, enable both by default. Leave
TRUSTFENCE_INITRAMFS_IMAGE as an internal variable only.

Add a new function to the recovery library to be able to encrypt/unencrypt any
partition on the internal storage media. Since it's a destructive operation,
add a warning message and a confirmation prompt that can be skipped if needed.
Reflect this new functionality in the recovery-reboot app. Change the logic so
that an encryption key can be set even if there's no update package, because
now it's possible to encrypt other partitions while leaving the rootfs intact.
Also change the logic so that the app doesn't reboot into recovery mode if
there's no recovery command set.
Implement the same blacklist as the one in the recovery script.

Modify the recovery and trustfence initramfs scripts to be able to encrypt any
partition on the internal storage media, not just the rootfs.
To implement this functionality, add a new recovery command called
'encrypt_partitions'. When used, this command must contain a comma-separated
list of the partitions that are to be encrypted by the end of the recovery
process, including partitions that were already encrypted beforehand. Any
partition that isn't in the list will be unencrypted. If the command is absent,
no changes will be made, but it's possible to pass an empty command to
unencrypt all partitions.
Include a blacklist to avoid encrypting partitions that shouldn't be encrypted,
such as partitions that need to be accessed by the ROM code/U-Boot or
partitions that contain encryption keys.
While at it, remove unnecessary "get_kernel_version" function from the script.
