Thanks. I had a few extant changes I had not yet published -- typos,
grammatical fixes in README, etc.

Also, I was unsure about whether the new header files should include the
RPC declarations, so that the same XDR header files could be used
directly by external RPC implementations.  The attached patch adds the
public ones.

Finally, when rebuilding, I found a thinko in xdr/Makefile.am:
"EXTRA_SOURCES" is a bad name -- automake gives the following warnings:
xdr/Makefile.am:20: variable `EXTRA_SOURCES' is defined but no program or
xdr/Makefile.am:20: library has `EXTRA' as canonical name (possible typo)

why this is a problem, but GENERAL_SOURCES and ELIX_SOURCES are not, I
don't know, but the attached fixes both that and regenerates xdr/Makefile.in

	* libc/xdr/README: Correct grammatical errors.
	* libc/include/rpc/types.h: Add public types used
	by RPC implementations.
	* libc/include/rpc/xdr.h: Add defines used by RPC
	implementations.
	* libc/xdr/Makefile.am: Eliminate automake warning.
	* libc/xdr/Makefile.in: Regenerate.
