All the NO_foo options processed in src.opts.mk are really bsd.opts.mk
options, so move their processing there. This fixes issues with
Makefiles that define NO_MAN=t and only inlcude bsd.*.mk files. A few
ports fell into this category, and they should be fixed by this change.
Also, for now, disable the warning about NO_foo being deprecated. More
work is needed than anticipated before we can do that, so kill the
noise for now.
bsd.compiler.mk was implicitly included by bsd.own.mk in historical
versions. With its movement to src.opts.mk, bsd.prog.mk was testing
COMPILER_TYPE without including the bsd.compiler.mk anymore. In the
source tree, this caused no problems, for reasons that aren't clear,
but does cause problems outside of the source tree. Allow
bsd.compiler.mk to be included multiple times safely, and always
include bsd.compiler.mk at the top of bsd.prog.mk. Resist the urge to
put it in bsd.init.mk, since that would reintroduce the implicit
include.
First cleanup pass: new sentence -> new line, mdoc, typos and style.
Generate hardware notes for mrsas(4).
Add casts to have it compile on amd64 without complaining about
mismatched types.

Modify release.xsl to allow proper attribution for
sponsored and/or contributed works.

This works similarly to how the subversion revision is
suffixed in release notes entries when 'revision="NNNNNN"'
is set.

The <para> tag in relnotes/article.xml can now take the
following new elements:

 - contrib: defined to what type of contribution the change
   is.  Right now, only 'vendor' or 'sponsor' are used.
   'vendor' is intended for vendor-contributed code, such as
   driver updates, etc.  'sponsor' is intended for sponsored
   work (the 'Sponsored by:' in the commit template).

 - vendor: The canonical name of the vendor.

 - sponsor: The canonical name of the sponsor.

 - vendorurl: The URL for the vendor website, if applicable.

 - sponsorurl: The URL for the sponsor website, if applicable.

If 'vendor' or 'sponsor' are set, but 'contrib' is not, nothing
is rendered.  If 'contrib' is set, but no 'vendor' or 'sponsor'
are defined, nothing is printed.  If 'vendorurl' or 'sponsorurl'
are set, the 'vendor' or 'sponsor' text is link, otherwise is
non-clickable text.

(dd_out): Fix handling of all-zeroes block at end of input with
conv=sparse.

This change fixes two separate issues observed when the last output
block is all zeroes, and conv=sparse is in use. In this case, care
must be taken to roll back the last seek and write the entire last zero
block at the original offset where it should have occurred: when the
destination file is a block device, it is not possible to roll back
by just one character as the write would then not be properly aligned.

Furthermore, the buffer used to write this last all-zeroes block
needs to be properly zeroed-out. This was not the case previously,
resulting in a junk data byte appearing instead of a zero in the
output stream.
