grembo 1fb18c4bde FreeBSD boot code reminder after zpool upgrade
There used to be a warning after upgrading a zpool in FreeBSD, so users
won't forget to update the boot loader that pool is booted from.

This change brings this warning back, but only if the bootfs property
is set on the pool, which should be sufficient for the vast majority of
FreeBSD installations. People running something custom are most likely
aware of what to do after an upgrade in their specific environment.

Functionality is implemented in an OS specific helper function.

/*
* Functions to convert between a list of vdevs and an nvlist representing the
* configuration. Each entry in the list can be one of:
*
* Device vdevs
* disk=(path=..., devid=...)
* file=(path=...)
*
* Group vdevs
* raidz[1|2]=(...)
* mirror=(...)
*
* Hot spares
*
* While the underlying implementation supports it, group vdevs cannot contain
* other group vdevs. All userland verification of devices is contained within
* this file. If successful, the nvlist returned can be passed directly to the
* kernel; we've done as much verification as possible in userland.
*
* Hot spares are a special case, and passed down as an array of disk vdevs, at
* the same level as the root of the vdev tree.
*
* The only function exported by this file is 'make_root_vdev'. The
* function performs several passes:
*
* 1. Construct the vdev specification. Performs syntax validation and
* makes sure each device is valid.
* 2. Check for devices in use. Using libdiskmgt, makes sure that no
* devices are also in use. Some can be overridden using the 'force'
* flag, others cannot.
* 3. Check for replication errors if the 'force' flag is not specified.
* validates that the replication level is consistent across the
* entire pool.
* 4. Call libzfs to label any whole disks with an EFI label.
