MFC r287396:

It's 2015, and some people are still trying to use fdisk and then
go asking what debug flags to set for GEOM to make it work. Advice
them to use gpart(8) instead.

Something similar should probably done with disklabel,
but I need to rewrite the disklabel examples first.

Add instructions for creating a ramdisk root image. These likely need
to be augmented with instructions for those platforms that have
/boot/loader.

Removed whitespace at end-of-line; no content changes. I simply did
cd src/share; find man[1-9] -type f|xargs perl -pi -e 's/[ \t]+$//'

BTW, what editors are the culprits? I'm using vim and it shows
me whitespace at EOL in troff files with a thick blue block...

Add missing article.

mdoc(7) police:
o Update document date.
o Remove hard sentence break.
o Sort xrefs.

Make md(4) more in line with reality.

NB: probably contains mdoc mistakes, feel free to fix.

Use Fx macro wherever possible.

Actually allow ``options MDNSECT=<numsects>'' in kernel configs to
specify the default maximum size of malloc(9)-backed md(4) devices
and complete the documentation of this option.

Add phk's md(4) manual page, written by phk himself.
