Discard unflexible structure based on the root/chapter/section layout in
favor of a generalized concept of section.

This should allow to represent sections at a generic level of nesting,
and allow subsection fields selection.

Also, simplify the code.

all versions of MinGW32 have broken implementations of
vsnprintf.

The parameter was never used.

Make writer_print_time() and writer_print_rational() always call
writer_print_int() or writer_print_string(). This way the checks for
determining if the value should be printed or not are consistently
performed in the low level functions.

writer_print_rational() is moved downward in order to avoid a forward
reference.

Simplify/amend the overall logic.
