Only converted the ones that are really sure (not signal-dependent)
and that shouldn't add much run-time complexity

We make sure the CELT PLC we do in the transition uses the same bandwidth
as the previous (CELT) packet and not the new bandwidth

Enables "safes" assertions even with ENABLE_ASSERTIONS isn't set

A second-order DC rejection filter is uselsss unless we have complex
poles. However, complex poles means we have to compute the filter as a
single pass (rather than two casdaded first-order filters), which has
numerical issues that would require a higher complexity to solve.
So rather than waste cycles with a second-order filter (with a longer
impulse response), we just go with a first-order filter.

It adds a libssp-0.dll dependency and prevents static linking

The size overhead seems to be about 1% and the speed overhead is
"in the noise" (<2%).
The automake code is copied from opus-tools

Fixes a "regression" from 1.2 to 1.3-beta that was especially noticeable
on a Korean speech sample. (it wasn't a real regression since 1.2 only
worked because it was using CELT)

This improves cases where a whole region is dominated by a handful of tones

Also adds the error terms for band 0 that were previously omitted

That corresponds to the fundamental for the shortest pitch period allowed

This makes it possible to link dynamically with an uninstalled libopus.
It does require the executable to use libtool however.
