Pass the list of user selected disks from zfsboot to bootconfig so that
the latter doesn't rely on ESP autodetection that apparently fails for
some cases, e.g. memstick installation with nvme (boot) and sata drives.
While here, fix printing of debug messages in bootconfig.

When using a gmirror, entries in /dev can be removed. So instead of using
kern.disks, get the list of disks from "gpart status -sg" instead.
We assume that any 'efi' partition that can't be mounted as msdosfs should
be used as an ESP. However, the ESP on the CD/DVD can't be mounted read-write
and so was being treated as if unformatted. Try the mount as read-only
instead, to catch cases like this.

Currently, the installer uses pre-created 800KB FAT12 filesystems that
it dd's onto the ESP partition.
This changeset improves that by having the installer generate a FAT32
filesystem directly onto the ESP using newfs_msdos and then copying
loader.efi into /EFI/freebsd.
For live installs it then runs efibootmgr to add a FreeBSD boot entry
in the BIOS.

Summary:
The kernel reads 'kernelname' to set the kern.bootfile sysctl. By setting this,
'make installkernel' will backup the running kernel as appropriate.

foundation for invoking efibootmgr as part of new-style EFI booting on
x86. On PS3 and PowerNV, which are booted using Linux kexec from petitboot
rather than by loader(8), install the kernel and the rest of /boot to a
FAT partition and set up the appropriate petitboot configuration file
there.
The new bootconfig installer stage can do platform-dependent modifications
more complex than partition layout and installation of boot blocks and can
be used to (as here) set up some special configuration files, run efibootmgr,
or boot0cfg.
