Move most of the remaining USD/PSD/SMM papers into share/doc

Correct typos, mostly s/ a / an / where appropriate. Some whitespace cleanup,
especially in troff files.

bsd.doc.mk changes:

Don't gratuitously pipe thru a cat(1) if NODOCCOMPRESS.

Only create _stamp.extra when necessary.

Get rid of SOELIMPP and OBJS.

Use Groff version of soelim(1); we need its -I option
for the following to work.

Don't needlessly chdir to SRCDIR. Only a few documents
need CD_HACK, and those that need it either use refer(1)
or .PSPIC macro which internally uses the .psbb call.

s/demon/daemon/

Eliminate groff(1) warnings.

Add Sun RPC documentation, which should eventually go into our PSD.
(I think I'm up to part 6.)
