Postgres FD Implementation

Fix copyright notices, other minor editing in new range-types code. 

No functional changes in this commit (except I could not resist the
temptation to re-word a couple of error messages).  This is just manual
cleanup after pgindent to make the code look reasonably like other PG
code, in preparation for more detailed code review to come.
