PR/13749 - Incorrect options specified for dd(1) in tape installs.

Cleanup dd options accordingly to the following policy:
1) put if, of, bs, conv in this order
2) for reading/writing from/to disk don't use sync
4) reading from tape - use sync
3) writing to tape - use osync

Fix some URLs. From OKANO Takayoshi in PR 33001.

Updated URL for list of NetBSD mirrors.

branches: 1.28.2;
Update text since there are now three install floppies. It's
written to cover the 2-floppy case as well, so if this file is
updated later with delta's needed on netbsd-2-0, this one revision
does not need to be excluded.

branches: 1.27.2;
- fix some typos (netsbd.org -> NetBSD.org)
- add trailing slashes to URLs where appropriate
- netbsd.org -> NetBSD.org

netbsd.org->NetBSD.org

consistently use Ic for sysinst

clean up whitespace, formatting, copyrights

branches: 1.23.2;
Replace tabs with spaces in two places inside .(disp, so that the
bootptab and dhcpd.conf entries are not brought flush against the
right margin, but instead get sane formatting.

Quote > and < characters with \*> and \*< in order to get semi-correct
HTML as one of the results.

Minor spelling fix. s/necesary/necessary/

more work:
- use .Tn, .Bx, .Ul, .Key, .Sq, .Dq, .Li, .Dl, (etc) ... as appropriate
- be more consistent between various ports' install notes
- other cleanups

major terraform (this is MUCH more than a rototill :-), including:
- update for 1.5 (still more MD stuff to check)
- use new macros in ../common/macros as appropriate
- introduce some CONSISTENCY between the various ports' install docs
- use various mdoc macros as appropriate, including .Li, .Pa, .Sy, and .Ic.
- migrate more stuff into ../common/*
- whitespace cleanup
- lots of other little things i'm sure...

s/tar xpfz/tar xpzf/

Add notes about steps to do after installation that are common to all
platforms; Thanks to Colin Wood and Simon Burge for their comments.

Keep trying to make this amount to something.

Improve the alternate unpacking shellcode.

Edits for toolchain installation.

Insert edits suggested by cgd@netbsd.org and fix the cpp alpha/*.tgz
unclosed-comment error. (sigh)

Note that a ./MAKEDEV all is needed, document the install script
functions, briefly describe a manual install, fix section cross
references, and other misc edits.

Correct spelling in */upgrade. More general editing in alpha/install.

Getting closer.

Modify ./contents + ./install;
* no more binary toolchain tarball
* source toolchain tarball still present
* some english
* add bs=18k on the floppy dd(1) example, just to be safe on systems
that don't like to cross cylinder boundaries (and it's faster)
Modify ./upgrade:
* untangle the first pp
