Subject: provide overridable root by subvol
References: fate#316522, fate#316232
Patch-Mainline: no
This patch provides a environment variable $subvol that can be used
to override path relative to absolute root by specific $subvol.
v1:
Introduce $boot_prefix for setting prefix on seeking other /boot
directory.

From: Michael Chang <mchang@suse.com>
Subject: create menus for btrfs snapshot
References: fate#316522, fate#316232
Patch-Mainline: no
This patch adds a new script that will create the menus used for
booting btrfs snapshots.
v1:
* Support existing snapshots by creating their missing slave configs.
* Temporarily default to disable this feature until receiving more
tests from QA.
* Introduce GRUB_ENABLE_CUSTOM_SNAPSHOT_SUBMENU to allow custom
submenu for listing snapshots rather than the default one.
v2:
* Fix bootable snapshots not found while root is on Btrfs subvolume
(bnc#859587)
* Create missing slave config in /.snapshots/<num>/
* Prefix with SUSE_ for related options
v3:
* When booting btrfs snapshots disabled, deleting snapshot master config
if it's not customized

From: Michael Chang <mchang@suse.com>
Subject: add loader_cmdline_append environment variable
Add loader_cmdline_append environment variable that appends it's
value to the loader's command line. We can use this variable to
assign values determined at run time. It will take effect on any
subsidiary configs loaded using configfile as well.
By means of this variable, we can, for example, set rootflags=
according to the selected btrfs snapshots and tell linux kernel's
btrfs module to mount the snapshot by the subvolume name or id.
