Doc: move info for btree opclass implementors into main documentation. Up to now, useful info for writing a new btree opclass has been buried in the backend's nbtree/README file. Let's move it into the SGML docs, in preparation for extending it with info about "in_range" functions in the upcoming window RANGE patch.
To do this, I chose to create a new chapter for btree indexes in Part VII (Internals), parallel to the chapters that exist for the newer index AMs. This is a pretty short chapter as-is. At some point somebody might care to flesh it out with more detail about btree internals, but that is beyond the scope of my ambition for today.
