Clean up use of error() versus ::error() in stream-based code.
* oct-fstrm.cc, oct-iostrm.cc, oct-strstrm.cc: Add comments before code that is
specifically using error from stream class rather than ::error from error.h
* oct-stream.cc: Overhaul file. Add programming note about difference between
error() and ::error() at top of file. Put input validation first. Cuddle
parentheses to variable when doing indexing. Declare variables as late as
possible. Wrap lines < 80 characters, but try to break comments into
intelligible blocks. Avoid declaring retval when returning a value would
do just as well.
