Rework internal data structures and "interfaces to user interface" functions
to get rid of all disklabel assumptions.

Previously (even for GPT partitioning) struct disklabel was used, which
obviously breaks large disk setups. Also many MD parts and parts of the
user interface assumed (a) a struct disklabel is used internally to
store partitioning information and (b) partitions are named 'a' ... $MAXPART.

Get rid of this and replace it with a quite abstract interface that should
be able to deal with all variants in partition storage:

- partitions are stored in a (partly abstract) struct disk_partitions
and most parts of it are only accessed via accessor functions provided
by a "partitioning scheme".

- implement partitioning schemes for MBR, disklabel and GPT (with likely
RDB [amiga] and Apple Partition Map [mac*] to follow soon)

- partitioning schemes may be cascaded, e.g. on x86 when using MBR as
"outer partitions", we have disklabel as "inner partitions".

- all user interface goes via accessor functions in the partitioning scheme,
some of which return pointers to special user interface descriptors
(e.g. to allow editing partition flags, which are scheme specific)

Overall the user interface changes (in this initial step) are minimal but
noticable. A new Anita is needed for automatic test setups - many thanks
to Andreas Gustafsson for lots of early testing and a new Anita version,
and to Manuel Bouyer for cooperation and tests of the Anita release.

Move sysinst sources to usr.sbin.

This commit only physically moves the sources - there are no other
changes, to maximize the probability that this will be treated as a
rename if we ever do manage to migrate away from CVS.

Moving sysinst has been discussed on and off for years and has two
goals: making it easier to work on sysinst, and also making sysinst
available on running systems for use installing chroots and VM images
and other such things. None of the latter is possible yet, but as they
say, one thing at a time.

Doing this now was approved in an impromptu fashion by mrg, riz,
riastradh, me, and groo.

When upgrading, update the boot code post extraction from
the updated target file system.

PR 55536: when we find existing partition tables and have alternative
formats available, offer to delete partitions and create new ones from
scratch (in some other or the same on-disk format).

Fix support for non-512-byte/sector disks again after I broke it when
introducing the abstract partition backends.

Finish conversion of extended partitioning parts to new abstract
backend interface. XXX still could use a lot of polishing.

Adapt MD parts to changes in get_fs_part_type (pass partition type).

When we ask the user to select a partitioning scheme and they refuse
(that is: select "Exit" in the menu), abort installation.

We may call md_pre_mount() multiple times for the same install set,
so pass an additional index argument so MD code knows which part
of the install will be mounted next.

Use _fmt_ msg_ methods when formats are needed.

In the new world order disks may come without any partitioning scheme
attached - so the user may have to select one.

More (ab-)usages of "yesno"

Backout the previous incorrect fix for PR 49440 and redo it more globaly:
get rid of the global "yesno", introduce utility functions "ask_yesno()"
and "ask_noyes()" instead, greatly simplifying a lot of code.
Pass in a pointer to the return value to various "set source" menus.

(Finally) merge a slightly modified version of the 2012 GSoC results
from Eugene Lozovoy: add extended partitioning options to sysinst.
Still needs some testing and polishing, but it now is possible to use GPT
or to create a RAID set from scratch and install onto it.

Define DEFSWAPSIZE properly. DEFSWAPRAM seems obsolete.

Split out /rescue to its own set and adapt installers/images to add it.

This is meant to make updates safer: if something goes wrong with updating
base, we still have the old, standalone /rescue to recover from.
