Remove CHS alignment. It's not needed and causes problems for the BBB
boot partition. NetBSD removed it in 1.10 in their repo some time ago.

r305075:
The code only converts from bpbHugeSectors to bpbSectors if the sum of
the hidden and huge sectors is less than or equal MAXU16. When
formatting in Windows bpbSectors is still used for 63488 sectors and
2048 hidden (sum > MAXU16). The hidden sectors count is the number of
sectors before the FAT16 Boot Record so it shouldn't affect the sector
count. Attached patch (huge_sec_conversion.patch) to only check for
bpb.bpbHugeSectors <= MAXU16 when converting to bpbSectors.

MFC r318355,318366: add -T (timestamp) option for reproducible builds

MFC r326276:

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

Fix build - cast off_t to (intmax_t) for printing.

Some useful operational extensions to newfs_msdos, especially
when preparing images for emulators or flash devices:

+ option '-C size' to create the underlying image file with given size.
Saves doing a 'dd' before, and especially it creates a sparse file

+ option '-@ offset' to build the FAT image at the specified offset
in the image file or device;

+ make the cluster size adaptive on the filesystem size.
Previously the default was 4k which is really unconvenient with
large media; now it goes from 512 bytes to 32k depending on
filesystem size (i still need to check whether it makes sense
to go further up, to 64k or above);

+ fix default geometry when not specified on the command line,
use 63 sectors/255 heads by default.
Also trim the size so it exactly a multiple of a track, to avoid
complaints in some filesystem code.

+ document all the above, plus some manual page clarifications.

MFC after: 4 weeks

Create a fake geometry (16 heads, 64 sectors) when dealing with
a plain file and a geometry is not explicitly supplied through
command line or disktab entry.

This way you can a FAT image on a file as simply as this:

newfs_msdos ./some/file

(right now you need a much longer command

newfs_msdos -h 32 -u 64 -S 512 -s $total_blocks -o 0 ./some/file
