Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

Microsoft recommends avoiding the use of spaces in the
string structures for FAT. Unfortunately they do just
that by default in the case of unlabeled filesystems.
Follow the default MS behavior to avoid confusion in
common tools like file(1). This was actually the
default behavior before r203868.

The fields from deMTime and deMDate in the DOS directory entry
are actually the last-modified time/date.
According to some online documentation these are the only
timestamps available in FAT12/FAT16.

The reasoning behind this, is that if we are consistent in our
documentation about the uint*_t stuff, people will be less tempted to
write new code that uses the non-standard types.
I am not going to bump the man page dates, as these changes can be
considered style nits. The meaning of the man pages is unaffected.

- Change the default volume label from "NO NAME" to "NO_NAME".
- Set OEM String to "BSD4.4 " following the unnamed spacing convention
in that other OS that suggests "MSWIN4.1"

Either use parameters provided by user or make them up.
The code for faking CHS params is borrowed from disklabel code.
The logic for using user-provided and auto-guessed parameters is not
perfect, so to speak.

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.

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
Will be merged after 7.1 and 6.4 are released.
