Pass the name of the compressor actually used for sets to groff and use
it in the content description (XXX need to adapt a few more copies in,
as of now, unaffected architectures)

Mention that USE_XZ_SETS are either always xzipped, and in evbarm might
be xzipped or gzipped.

Modernize release notes:
- use https where possible
- adapt to cdn/nycdn and our current auto-build conventions
- automate where possible
Many thanks to uwe for lots of *roff help.

Pass the set suffix (either .tgz or .tar.xz) from the makefile.
Document the rescue set.

Move common/contents file into MD dirs again.
I know it isn't a good thing to have many copy-and-pasted contents
(set file descriptions etc) in all MD files, but it's much more annoying
to maintain a bunch of .if \n [${MACHINE}] conditionals for all ports
and maintainers rarely notice that they also have to prepare or update
MD contents in MI content file with messy ifdefs.

XXX: of course common text should be shared by mdoc macro etc.
but I doubt playing mdoc(7) is really worth...

migrate */contents -> common/contents, as there was *way* too much
unnecessary duplication. wrap the MD stuff in .if r_foo \{\ ... .\}

update copyright date

We ship XFree 3.3.6 these days, not 3.3.3.1.

Remove paragraph about secr set.

branches: 1.10.8;
* Delete sun3x from SUBDIR
* The merged contents file didn't work out, so nuke it and put it back
into each port directory. Most still have the now-pointless conditionals;
these now should be deleted.
* fix alpha, amiga, and arm32 to delete the maze of twisty little conditionals

Remove these before someone changes them. There is a common contents file
in distrib/notes/common/contents, conditionalized for the differences
between platform distributions.

1) Remove all vestiges of tar from src/distrib. Use pax and appropriate
commandlines for all tar operations. (work supplied by Matt Green)
2) Update arch/*/md.c to deal with new sysinst/run.c. Special case
anything that needs to do a redirect or a pipe.
3) #if 0 some unused code in target.c. This code will need to be updated,
or special cased with do_system.

Big thank you to Matt for all his work on this.

More edits to make these instructions apply to snapshots as well as
releases. There is now a #if _FOR_RELEASE that selects text blocks.

Edits for toolchain installation.

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

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
