This change makes the following improvements:

* Explain how very long strings are stored in a data file.

* Correct descriptions of data types and describe how PSPP actually detects
integer and floating-point formats.

* Make it easier to understand the record ordering.

* Don't try so hard to make the format descriptions look like C structs.

* Define "dictionary index".

* Reformat list of format types to make it easier to read.

* Combine value labels record, value labels variable record into a single
section, for clarity.

* Rename "auxiliary variable parameter record" to "variable display parameter
record", which is more descriptive.

* General proofreading.

I have a followup change that improves the sys-file-reader and
sys-file-writer code.  It's not quite ready yet.
