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.

Do not use rlelen field for buffer size in init_get_bits, it is
only the size of the data for the first field.
Since it is not reliable, just use the size of the whole buffer.

Additional comments add removal of unused rlelen variable by
Reimar Döffinger.

This avoids using the global_quality field and QSCALE flag for
passing the VBR modes, since the value range of the global_quality
field doesn't really map cleanly to this codec's VBR modes.

These modes were not originally exposed by the library at all.
In practice, only a few of them work for each sample rate/profile
combination, and they don't work at all for the more uncommon
sample rates.

This code runs on the host and should not use libm.h, which is meant

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.
