Clean up readline doc subdir to conform to normal

configure/distribution practices.

Makefile: remove, replacing with a configurable Makefile.in

texindex.c texinfo.tex: remove, replacing with references to tools elsewhere
                        in Cygnus distribution tree.

Makefile.in: configurable (and useable) Makefile.

configure.in: pro forma configure stub.
