sysinst: Center the select_part_scheme menu horizontally

sysinst: remove trailing whitespace from *.c *.h

In contrast to the messages files, this whitespace is not significant.

Minor fix to previous: fix condition when we offer the partition type
switch - it makes sense even if the disk is partitioned but has no valid
partitions.

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 editing start and size of not yet existing outer partitions.

Remove more pm->ptstart abuse - calculate values localy where needed
instead.

When creating new partitions for "full disk" use, pass a install target
hint to the partitioning backend (for the outer NetBSD partition).

When MD code requests a reserved area (at the start of the disk)
make sure to properly account for the "lost" space during all calculations
and especially when expanding the main partition to fill the disk.

Avoid using the global "pm" or a passed device descriptons when we are
passing disk limits explicitly anyway.

Simplify/fix a few rounding calculations.

PR 55384: detangle pm->ptstart from the "install" flag (selecting a
target partition). Instead introduce a new PTI_INSTALL_TARGET per partition
flag and deal with it in the partitioning backends.

Honour pm->ptstart when allocating new partitions - it is supposed to be
the first sector usable by NetBSD.

PR 55381: try to deal with moved (but not yet saved) partitions when
calculating free space

branches: 1.16.4;
Fix support for non-512-byte/sector disks again after I broke it when
introducing the abstract partition backends.

First try to bring evbarm installation closer to current reality.

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

Drop unused variable.

Make cloning support optional, so we can save some space on very small
install media.

Add options to the various partitioning stages that allow cloning of
alien partitions (optionally including data).

In non-MBR specific files, #ifdef all tests for MBR for architectures
that do not even compile in MBR support.

Honor the "no_mbr" flag (used especially for raid and xbd devices)

When we fail to setup for "all of the disk for NetBSD" report
failure, instead of silently aborting the install.

branches: 1.7.2;
Fix copy & pasto: when using the whole disk but requiring boot partitions,
do not extend the size of the boot partition(s) to full disk size.

When editing outer partitions:
- when there are no outer partitions to edit, just report success and go
on, instead of failing an assertion.
- use the partitions passed as argument and avoid refering (the hopefully
same set) via the global pm device pointer.

When checking for pre-exisiting partitions, skip non-user partitions
(like the raw partition in disklabel, or extended partitions in MBR).

no need to initialize fields that are already 0.

Use _fmt_ msg_ methods when formats are needed.

Lower estimates on required install size

When setting up a "use whole disk" single outer partition, force an
empty set of inner partitions immediately,

This avoids reading old (stale) partitions (e.g. disklabel that
survived cleaning and re-creating the MBR with the MBR NetBSD partition
starting at the same offset) later.

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.

Lower estimates on required install size

When setting up a "use whole disk" single outer partition, force an
empty set of inner partitions immediately,

This avoids reading old (stale) partitions (e.g. disklabel that
survived cleaning and re-creating the MBR with the MBR NetBSD partition
starting at the same offset) later.

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.

First try to bring evbarm installation closer to current reality.

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

Drop unused variable.

Make cloning support optional, so we can save some space on very small
install media.

Add options to the various partitioning stages that allow cloning of
alien partitions (optionally including data).

In non-MBR specific files, #ifdef all tests for MBR for architectures
that do not even compile in MBR support.

Honor the "no_mbr" flag (used especially for raid and xbd devices)

When we fail to setup for "all of the disk for NetBSD" report
failure, instead of silently aborting the install.

branches: 1.7.2;
Fix copy & pasto: when using the whole disk but requiring boot partitions,
do not extend the size of the boot partition(s) to full disk size.

When editing outer partitions:
- when there are no outer partitions to edit, just report success and go
on, instead of failing an assertion.
- use the partitions passed as argument and avoid refering (the hopefully
same set) via the global pm device pointer.

When checking for pre-exisiting partitions, skip non-user partitions

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.

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.
